1
00:00:00,560 --> 00:00:04,000
Speaker 1: Welcome to Stuff you missed in History Class from housetof

2
00:00:04,120 --> 00:00:13,640
Speaker 1: works dot com. Hello, and welcome to the podcast. I'm

3
00:00:13,680 --> 00:00:16,159
Speaker 1: Debline and Chok reporting and I'm fair douting. And we

4
00:00:16,280 --> 00:00:20,400
Speaker 1: recently did an episode on nineteenth century dentist Horace Wells

5
00:00:20,440 --> 00:00:24,400
Speaker 1: in his battle to receive credit for discovering inhalation anesthesia.

6
00:00:24,880 --> 00:00:27,840
Speaker 1: And that episode was really fascinating to research, just to

7
00:00:27,920 --> 00:00:31,360
Speaker 1: find out about the rivalries that were created because of

8
00:00:31,360 --> 00:00:34,640
Speaker 1: this discovery and the lengths that they would go to

9
00:00:34,640 --> 00:00:38,519
Speaker 1: to get credit or discredit one another, and all this

10
00:00:38,840 --> 00:00:41,239
Speaker 1: for a discovery that was supposed to be for the

11
00:00:41,280 --> 00:00:44,160
Speaker 1: benefit of everyone, something that maybe people shouldn't have fought

12
00:00:44,280 --> 00:00:47,360
Speaker 1: over quite as much as they did. So it definitely

13
00:00:47,440 --> 00:00:50,479
Speaker 1: got us interested in exploring some more of those science

14
00:00:50,520 --> 00:00:53,680
Speaker 1: related rivalries. Yeah, and of course one of the most

15
00:00:53,680 --> 00:00:57,440
Speaker 1: famous also involved one of our most requested historical figures.

16
00:00:57,440 --> 00:00:59,000
Speaker 1: I feel like we always say that, but this one

17
00:00:59,120 --> 00:01:02,600
Speaker 1: really is requested a lot. Is the big time, and

18
00:01:02,680 --> 00:01:07,080
Speaker 1: that's Nicola Tesla. Tesla's probably most famous for inventing a

19
00:01:07,120 --> 00:01:09,520
Speaker 1: safe and effective motor that could be used to deliver

20
00:01:09,600 --> 00:01:13,880
Speaker 1: electricity using alternating current, and that alternating current method is

21
00:01:13,880 --> 00:01:16,919
Speaker 1: still used today, But he also invented the Tesla coil

22
00:01:17,400 --> 00:01:20,600
Speaker 1: and induction coil used in radio technology and many other

23
00:01:20,680 --> 00:01:23,080
Speaker 1: things which we will mention in a bit, But it

24
00:01:23,160 --> 00:01:26,959
Speaker 1: was that first invention and simply Tesla's devotion to the

25
00:01:27,040 --> 00:01:30,440
Speaker 1: idea that alternating current was superior to direct current as

26
00:01:30,520 --> 00:01:35,200
Speaker 1: a means of delivering electricity that sparked a bitter rivalry

27
00:01:35,360 --> 00:01:39,600
Speaker 1: with a very well known, very accomplished American inventor, Thomas Edison.

28
00:01:39,680 --> 00:01:42,720
Speaker 1: Of course, so we're going to be exploring Tesla's life,

29
00:01:42,800 --> 00:01:46,440
Speaker 1: his contributions, his eccentricities, but we're also going to take

30
00:01:46,480 --> 00:01:50,360
Speaker 1: a closer look at the contentious relationship that he had

31
00:01:50,360 --> 00:01:53,080
Speaker 1: with Edison and the battle that they fought in the

32
00:01:53,160 --> 00:01:56,120
Speaker 1: late nineteenth century to electrify the world. There was a

33
00:01:56,160 --> 00:01:59,120
Speaker 1: lot at stake, so by the time you get to

34
00:01:59,120 --> 00:02:01,120
Speaker 1: the end of Tesla's story, will really want to know

35
00:02:01,160 --> 00:02:03,800
Speaker 1: how minds like his got its starts. So that's where

36
00:02:03,840 --> 00:02:07,120
Speaker 1: we're going to begin. Tussa was born on July nine

37
00:02:07,240 --> 00:02:10,840
Speaker 1: or ten, sources tend to differ on that, eighteen fifty six,

38
00:02:11,200 --> 00:02:14,040
Speaker 1: into a family of Serbian origin in a village and

39
00:02:14,120 --> 00:02:17,839
Speaker 1: a part of Austria, Hungary, that's now Croatia. His dad

40
00:02:17,919 --> 00:02:20,559
Speaker 1: was an Orthodox priest and his mom was a homemaker

41
00:02:20,600 --> 00:02:24,120
Speaker 1: who hadn't had much, if any schooling, but she was

42
00:02:24,160 --> 00:02:27,440
Speaker 1: said to be very smart and really inventive to According

43
00:02:27,480 --> 00:02:31,280
Speaker 1: to PBS dot Org, Tesla's mom would invent all sorts

44
00:02:31,280 --> 00:02:34,120
Speaker 1: of gadgets to just help her around the house, including

45
00:02:34,480 --> 00:02:38,560
Speaker 1: a mechanical egg beater, and apparently Tesla later credited her

46
00:02:38,720 --> 00:02:41,960
Speaker 1: for his own inventive tendencies. His parents, though, kind of

47
00:02:42,000 --> 00:02:45,440
Speaker 1: expected their son to follow in his father's footsteps, but

48
00:02:45,720 --> 00:02:48,880
Speaker 1: he really excelled in math and science from an early age,

49
00:02:48,880 --> 00:02:52,640
Speaker 1: and it soon became pretty apparent that further academic achievement

50
00:02:52,680 --> 00:02:54,639
Speaker 1: along those lines was what he was going to try

51
00:02:54,639 --> 00:02:58,000
Speaker 1: to pursue. And he wasn't just plain old book smart too.

52
00:02:58,000 --> 00:03:00,880
Speaker 1: We should get into that before we start talking about

53
00:03:00,960 --> 00:03:04,119
Speaker 1: his his genius. Even when he was very young, he

54
00:03:04,240 --> 00:03:08,359
Speaker 1: was really inventive and imaginative and even had a bit

55
00:03:08,360 --> 00:03:11,680
Speaker 1: of a literary side to him. Yeah. According to Mental Floss,

56
00:03:11,760 --> 00:03:15,160
Speaker 1: Tesla had both conceived of an idea for a water wheel,

57
00:03:15,520 --> 00:03:18,920
Speaker 1: a machine for converting water to electricity, and read the

58
00:03:18,960 --> 00:03:22,519
Speaker 1: one hundred volume set of the Complete Voltaire by age five,

59
00:03:22,760 --> 00:03:26,520
Speaker 1: so pretty impressive. That it is pretty impressive. Not everybody

60
00:03:26,520 --> 00:03:28,760
Speaker 1: can even read yet at five, So there you go.

61
00:03:29,000 --> 00:03:31,520
Speaker 1: That's true. He was a little ahead of the curve there.

62
00:03:32,040 --> 00:03:35,600
Speaker 1: But in eighteen seventy five, Tesla moved to Gratz, Austria

63
00:03:35,680 --> 00:03:38,840
Speaker 1: to attend the Technical University there and trained to become

64
00:03:38,880 --> 00:03:42,440
Speaker 1: an engineer. According to an article about Tesla and notable

65
00:03:42,480 --> 00:03:45,840
Speaker 1: scientists from nineteen hundred to the present, it's while he

66
00:03:45,920 --> 00:03:48,800
Speaker 1: was there that he first saw a demonstration of the

67
00:03:48,920 --> 00:03:52,720
Speaker 1: Graham dynamo, a direct current induction motor. And while he

68
00:03:52,840 --> 00:03:56,440
Speaker 1: saw that demonstration, he noticed something. He saw that sparks

69
00:03:56,640 --> 00:03:59,800
Speaker 1: flew well it operated, and that's when he got this

70
00:04:00,000 --> 00:04:02,480
Speaker 1: idea of coming up with a method that would overcome

71
00:04:02,720 --> 00:04:06,680
Speaker 1: issues with direct current motor. So, after God, there's a

72
00:04:06,720 --> 00:04:09,880
Speaker 1: bit of lost time in Tesla's biography during which he

73
00:04:09,960 --> 00:04:12,800
Speaker 1: was ill, and apparently he would just study and study

74
00:04:12,800 --> 00:04:15,920
Speaker 1: and work on his ideas so hard sometimes that he

75
00:04:15,960 --> 00:04:19,000
Speaker 1: would make himself physically thick, or at least that's how

76
00:04:19,160 --> 00:04:22,080
Speaker 1: his his father saw it, anyway, and it really alarmed

77
00:04:22,120 --> 00:04:24,240
Speaker 1: his parents enough that they tried to get him to

78
00:04:24,720 --> 00:04:27,440
Speaker 1: switch career path. They just thought this was not going

79
00:04:27,480 --> 00:04:30,599
Speaker 1: to be healthy for their son. Eventually, though, Tesla said

80
00:04:30,640 --> 00:04:33,640
Speaker 1: to have moved on to continuous education at the University

81
00:04:33,640 --> 00:04:37,640
Speaker 1: of Prague, although according to biographer Margaret Cheney and Tesla

82
00:04:37,760 --> 00:04:40,479
Speaker 1: and Man out of Time, there's no record that he

83
00:04:40,520 --> 00:04:44,320
Speaker 1: actually went there. He may have just audited classes and

84
00:04:44,560 --> 00:04:49,159
Speaker 1: or use the libraries there regardless. By January eighteen eighty one,

85
00:04:49,400 --> 00:04:52,039
Speaker 1: he'd moved to Budapesh where he took a job in

86
00:04:52,080 --> 00:04:56,680
Speaker 1: the Hungarian government's Central Telegraph Office. In eight two, he

87
00:04:56,760 --> 00:04:59,360
Speaker 1: moved to Paris to take a position with the Continental

88
00:04:59,520 --> 00:05:03,680
Speaker 1: Edison Company, where his job was to address technical problems

89
00:05:03,720 --> 00:05:07,200
Speaker 1: in edison plants in both France and Germany, and according

90
00:05:07,200 --> 00:05:10,520
Speaker 1: to Encyclopedia Britannica, it's well he was on assignment in

91
00:05:10,560 --> 00:05:14,560
Speaker 1: Strasbourg in eighteen eighty three that Tesla really began serious

92
00:05:14,600 --> 00:05:17,159
Speaker 1: work on his first induction motor and came up with

93
00:05:17,200 --> 00:05:19,520
Speaker 1: a design for that, but he couldn't get a lot

94
00:05:19,520 --> 00:05:22,440
Speaker 1: of support for or interest in it, so it was

95
00:05:22,600 --> 00:05:25,440
Speaker 1: time for a big move. At that point, he decided

96
00:05:25,440 --> 00:05:28,080
Speaker 1: that he would head to America and see if he

97
00:05:28,120 --> 00:05:31,040
Speaker 1: could garner shake up some interest over there, So he

98
00:05:31,120 --> 00:05:33,880
Speaker 1: set sail in eighteen eighty four. He was in his

99
00:05:33,960 --> 00:05:36,760
Speaker 1: late twenties by this point, and he showed up that

100
00:05:36,839 --> 00:05:40,400
Speaker 1: summer with only four cents in his pocket, as well

101
00:05:40,440 --> 00:05:43,960
Speaker 1: as a few poems he had written and some calculations

102
00:05:44,000 --> 00:05:46,720
Speaker 1: for a flying machine that he wanted to create. That

103
00:05:46,760 --> 00:05:49,640
Speaker 1: really paints a good picture of him, I think, and

104
00:05:49,920 --> 00:05:53,800
Speaker 1: according to an article in American History by Ronald H. Bailey,

105
00:05:53,920 --> 00:05:56,880
Speaker 1: Tesla also only had one outfit left by the time

106
00:05:56,880 --> 00:05:59,159
Speaker 1: he got to the United States. It consisted of a

107
00:05:59,200 --> 00:06:03,680
Speaker 1: bowler hat, striped trousers and a cutaway coat, and all

108
00:06:03,720 --> 00:06:06,159
Speaker 1: of the rest of his clothing and his stuff he

109
00:06:06,160 --> 00:06:08,560
Speaker 1: had brought with him had been stolen on the trip over.

110
00:06:08,800 --> 00:06:11,279
Speaker 1: He also had a reference from the manager of the

111
00:06:11,440 --> 00:06:14,279
Speaker 1: Edison Company in Paris with him too. He so he

112
00:06:14,360 --> 00:06:16,880
Speaker 1: had like a recommendation along with him as well, because

113
00:06:17,120 --> 00:06:19,560
Speaker 1: he wanted a job with Edison's company in the States.

114
00:06:19,640 --> 00:06:21,640
Speaker 1: But there was a little more to it than just that.

115
00:06:21,680 --> 00:06:24,440
Speaker 1: There was a little more of a motive behind him

116
00:06:24,440 --> 00:06:28,000
Speaker 1: wanting to get work with Edison. Edison, who was thirty

117
00:06:28,040 --> 00:06:31,400
Speaker 1: seven at this time, was already considered a celebrated inventor.

118
00:06:31,880 --> 00:06:35,560
Speaker 1: He'd invented the incandescent light bulb and the phonograph and

119
00:06:35,600 --> 00:06:39,520
Speaker 1: had recently created a system for providing electricity to homes

120
00:06:39,520 --> 00:06:41,880
Speaker 1: and businesses that people in the New York City area

121
00:06:41,960 --> 00:06:45,960
Speaker 1: were already benefiting from. Tesla hoped that he could get

122
00:06:46,040 --> 00:06:49,520
Speaker 1: Edison support for his ideas about alternating current, and that's

123
00:06:49,560 --> 00:06:52,360
Speaker 1: why he wanted to kind of ring him up, get

124
00:06:52,480 --> 00:06:54,640
Speaker 1: Edison in his corner. Yeah, So he went to see

125
00:06:54,760 --> 00:06:58,239
Speaker 1: Edison almost immediately after arriving in New York, and according

126
00:06:58,279 --> 00:07:01,680
Speaker 1: to Bailey's article, lay Or wrote that he was thrilled

127
00:07:01,680 --> 00:07:04,480
Speaker 1: to the marrow to meet him. But it was clear

128
00:07:04,520 --> 00:07:07,159
Speaker 1: from the start that these two guys, although they were

129
00:07:07,160 --> 00:07:11,280
Speaker 1: both great minds, were complete opposites, even in the way

130
00:07:11,320 --> 00:07:14,120
Speaker 1: they looked and acted. I mean, Edison was short, pudgy,

131
00:07:14,320 --> 00:07:17,400
Speaker 1: disheveled and kind of folks see you well. Tesla was

132
00:07:17,440 --> 00:07:22,000
Speaker 1: more than six feet tall and slender, neatly dressed and formal,

133
00:07:22,200 --> 00:07:26,040
Speaker 1: very serious looking. But of course, the biggest difference between

134
00:07:26,040 --> 00:07:27,960
Speaker 1: these two guys was not just how they looked, it

135
00:07:28,000 --> 00:07:31,720
Speaker 1: was their beliefs about the way electricity should be distributed,

136
00:07:32,080 --> 00:07:35,720
Speaker 1: direct current or alternating current. So, before we go any

137
00:07:35,720 --> 00:07:38,240
Speaker 1: further would probably help out to give just a little

138
00:07:38,240 --> 00:07:40,880
Speaker 1: bit of background on the difference between direct current and

139
00:07:40,960 --> 00:07:43,840
Speaker 1: alternating current, just to give you guys a sense of

140
00:07:43,880 --> 00:07:47,360
Speaker 1: what Edison and Tesla disagreed about. So we're gonna stick

141
00:07:47,400 --> 00:07:50,560
Speaker 1: to the real, bare bone basics here because this isn't

142
00:07:50,560 --> 00:07:55,080
Speaker 1: a science podcast. We're not scientists or electricians or engineers,

143
00:07:55,080 --> 00:07:58,680
Speaker 1: but just to give you something to start with. So

144
00:07:58,840 --> 00:08:02,280
Speaker 1: by this point, scientific US had already researched electricity for

145
00:08:02,320 --> 00:08:04,800
Speaker 1: a while and people knew it was valuable. It was

146
00:08:04,840 --> 00:08:07,200
Speaker 1: just a matter of how to get it where it

147
00:08:07,320 --> 00:08:10,800
Speaker 1: needed to go, and Edison believed that direct current was

148
00:08:10,840 --> 00:08:14,640
Speaker 1: the answer to this. In a direct current, electrons, which

149
00:08:14,640 --> 00:08:18,880
Speaker 1: are the particles that convey electricity, just travel in one direction,

150
00:08:19,360 --> 00:08:21,840
Speaker 1: and a lot of Edison's inventions ran off of this

151
00:08:21,920 --> 00:08:25,520
Speaker 1: type of power. According to an article in American Heritage

152
00:08:25,600 --> 00:08:29,960
Speaker 1: by Bernard W. Carlson, Edison preferred this method because it

153
00:08:30,000 --> 00:08:32,920
Speaker 1: was simple and safe, but the downside is that it

154
00:08:32,920 --> 00:08:37,040
Speaker 1: could only move electricity for short distances. His early power

155
00:08:37,080 --> 00:08:40,560
Speaker 1: stations could only reach customers within about a miles distance,

156
00:08:40,840 --> 00:08:44,640
Speaker 1: so Tesla's preferred method. On the other hand, alternating current

157
00:08:45,440 --> 00:08:49,040
Speaker 1: involve electrons switching back and forth, so they travel first

158
00:08:49,080 --> 00:08:51,600
Speaker 1: in one direction and then in the other direction, and

159
00:08:51,600 --> 00:08:54,080
Speaker 1: they do this many many times per second. So if

160
00:08:54,120 --> 00:08:57,520
Speaker 1: you see something that's labeled sixty hurts, for instance, that

161
00:08:57,559 --> 00:09:01,080
Speaker 1: means that the current is changing direction in sixty times

162
00:09:01,080 --> 00:09:05,079
Speaker 1: per second. So alternating current is more difficult to set up,

163
00:09:05,120 --> 00:09:08,120
Speaker 1: but Tesla really believed in it because it was capable

164
00:09:08,320 --> 00:09:12,600
Speaker 1: of distributing electricity across greater distances, and it allowed you

165
00:09:12,679 --> 00:09:17,160
Speaker 1: to step up or decrease the voltage when you needed

166
00:09:17,200 --> 00:09:20,720
Speaker 1: to make something like that happen. He also felt, Carlson

167
00:09:20,760 --> 00:09:24,680
Speaker 1: writes that alternating current would enable people to use electricity

168
00:09:24,760 --> 00:09:29,520
Speaker 1: for more than just lighting, including running factory machines, street cars,

169
00:09:29,600 --> 00:09:33,319
Speaker 1: and elevators. So there was a lot of potential potential exactly.

170
00:09:33,880 --> 00:09:37,640
Speaker 1: Edison wasn't buying it. Though he wasn't buying into this idea,

171
00:09:37,720 --> 00:09:40,560
Speaker 1: he thought that Tesla's designs for the new induction motor

172
00:09:40,600 --> 00:09:45,720
Speaker 1: were both impractical and unsafe. According to Bailey's article, Tesla

173
00:09:45,840 --> 00:09:49,640
Speaker 1: later recalled that Edison said, quote very bluntly, that he

174
00:09:49,720 --> 00:09:53,480
Speaker 1: was not interested in alternating current. Anyone who dabbled in

175
00:09:53,520 --> 00:09:56,840
Speaker 1: that field was wasting his time. Still, though at least

176
00:09:56,920 --> 00:10:01,040
Speaker 1: at first, Edison was impressed by Tesla himself even if

177
00:10:01,040 --> 00:10:05,920
Speaker 1: he didn't like his electricity philosophy. He was impressed enough,

178
00:10:05,960 --> 00:10:08,960
Speaker 1: in fact, that he gave Tesla a job, and so Tesla,

179
00:10:09,280 --> 00:10:11,560
Speaker 1: with his four cents in his pocket, you know, swallowed

180
00:10:11,600 --> 00:10:14,520
Speaker 1: his pride, took the job and got to work at

181
00:10:14,640 --> 00:10:17,880
Speaker 1: Edison's Pearl Street power station. And his job there was

182
00:10:17,920 --> 00:10:21,720
Speaker 1: to improve the performance of the dynamos, or the generators,

183
00:10:21,760 --> 00:10:26,000
Speaker 1: and interestingly, the direct current generators actually worked by creating

184
00:10:26,080 --> 00:10:29,200
Speaker 1: alternating current, at least initially. Then they had converted to

185
00:10:29,240 --> 00:10:32,200
Speaker 1: the direct current right before it was transmitted by using

186
00:10:32,280 --> 00:10:36,079
Speaker 1: something called a commutator. This gig only lasted a few

187
00:10:36,120 --> 00:10:38,560
Speaker 1: months for Tesla, though, and that was for a couple

188
00:10:38,559 --> 00:10:42,120
Speaker 1: of reasons. First off, the fundamental differences between him and

189
00:10:42,280 --> 00:10:46,320
Speaker 1: Edison were just too great. He just really felt limited

190
00:10:46,360 --> 00:10:49,240
Speaker 1: by the position and unsatisfied with what he was doing

191
00:10:49,280 --> 00:10:52,000
Speaker 1: because he didn't really believe in it. But there was

192
00:10:52,040 --> 00:10:55,360
Speaker 1: also a situation regarding payment that caused Tesla to call

193
00:10:55,400 --> 00:10:59,480
Speaker 1: it quits. Tesla said Edison promised to pay him fifty

194
00:10:59,600 --> 00:11:03,079
Speaker 1: thousand dollars if he was successful in enhancing the power

195
00:11:03,160 --> 00:11:08,280
Speaker 1: stations dynamos, but after Tesla actually delivered on this, Edison

196
00:11:08,360 --> 00:11:11,520
Speaker 1: said that it was all a joke. According to PBS

197
00:11:11,600 --> 00:11:15,600
Speaker 1: dot org, the older inventor said something to the effective quote,

198
00:11:16,200 --> 00:11:19,080
Speaker 1: when you're a full fledged American, you can get an

199
00:11:19,120 --> 00:11:22,960
Speaker 1: American joke. Maybe yeah, not very nice. But according to

200
00:11:22,960 --> 00:11:26,520
Speaker 1: Bailey's article, Edison wouldn't even raise tesla salary from eighteen

201
00:11:26,559 --> 00:11:29,439
Speaker 1: dollars to twenty five dollars a week, so he didn't

202
00:11:29,559 --> 00:11:32,480
Speaker 1: even get some compensation for not getting the joke right.

203
00:11:32,559 --> 00:11:35,280
Speaker 1: So Tesla left and struck out on his own, and

204
00:11:35,320 --> 00:11:38,199
Speaker 1: this time he was determined to do things his own way,

205
00:11:38,440 --> 00:11:41,000
Speaker 1: but things still didn't go so well at first. He

206
00:11:41,160 --> 00:11:45,640
Speaker 1: started his own electric company in Rahway, New Jersey five

207
00:11:45,760 --> 00:11:48,920
Speaker 1: but the first real project he worked on after breaking

208
00:11:48,960 --> 00:11:51,720
Speaker 1: ties with Edison didn't have that much to do with

209
00:11:51,760 --> 00:11:55,200
Speaker 1: furthering his ideas about alternating current. He kind of got

210
00:11:55,240 --> 00:11:57,680
Speaker 1: out of the business almost There were some New Jersey

211
00:11:57,720 --> 00:12:01,040
Speaker 1: businessmen who hired him to improve the lighting system in

212
00:12:01,080 --> 00:12:04,000
Speaker 1: the city of Raleigh, but they wanted him to improve

213
00:12:04,120 --> 00:12:07,959
Speaker 1: upon an early system known as arc lighting. So Tesla

214
00:12:08,040 --> 00:12:10,199
Speaker 1: took the job because you know, it was at least

215
00:12:10,200 --> 00:12:12,840
Speaker 1: some kind of business, and he did create a better

216
00:12:12,960 --> 00:12:15,199
Speaker 1: type of arc lighting for the city, or a better

217
00:12:15,280 --> 00:12:19,040
Speaker 1: system of arc lighting, but the investors ended up taking

218
00:12:19,200 --> 00:12:22,079
Speaker 1: all the money that was earned from the project for themselves,

219
00:12:22,640 --> 00:12:26,000
Speaker 1: leaving Tesla with nothing, and according to Bailey, again they

220
00:12:26,040 --> 00:12:28,679
Speaker 1: even cheated the inventor out of the patents that he

221
00:12:28,720 --> 00:12:32,160
Speaker 1: had gotten for that new, improved arc light he'd created.

222
00:12:32,800 --> 00:12:36,400
Speaker 1: After that awful experience, Tesla was broke again and he

223
00:12:36,480 --> 00:12:39,320
Speaker 1: had to resort to working as a common laborer, and

224
00:12:39,360 --> 00:12:41,720
Speaker 1: to add insult to injury, one of his jobs was

225
00:12:41,840 --> 00:12:45,480
Speaker 1: digging ditches that would hold the electrical lines of none

226
00:12:45,520 --> 00:12:49,839
Speaker 1: other than Edison's direct current grid. So we're gonna leave

227
00:12:49,880 --> 00:12:52,640
Speaker 1: you there for now, with Tesla at a serious low

228
00:12:52,880 --> 00:12:55,440
Speaker 1: and the ditch. But if you're a huge Tesla fan,

229
00:12:55,559 --> 00:12:58,760
Speaker 1: don't worry, because in part two, his luck does change,

230
00:12:59,240 --> 00:13:01,480
Speaker 1: and we'll see what happens when Tesla gets some work

231
00:13:01,520 --> 00:13:04,200
Speaker 1: done on that induction motor of his that he designed

232
00:13:04,240 --> 00:13:07,240
Speaker 1: so long ago and the current war really starts to

233
00:13:07,280 --> 00:13:10,120
Speaker 1: heat up. We'll also take a look at Tesla's post

234
00:13:10,200 --> 00:13:13,400
Speaker 1: current war life, including how he earned the nickname Master

235
00:13:13,520 --> 00:13:17,439
Speaker 1: of Lightning and why some remember this one studious student

236
00:13:17,720 --> 00:13:22,000
Speaker 1: as a mad scientist. So plenty in store for a

237
00:13:22,120 --> 00:13:25,280
Speaker 1: Part two of Tesla Okay, what do we have on

238
00:13:25,320 --> 00:13:31,800
Speaker 1: the plate for a listener mail today? We have one

239
00:13:31,840 --> 00:13:35,120
Speaker 1: email here from listener Lavan and she says, just listen

240
00:13:35,200 --> 00:13:37,640
Speaker 1: to the Horace Wells episode while doing my morning walk

241
00:13:37,679 --> 00:13:39,679
Speaker 1: and had to let you know that I was in Washington,

242
00:13:39,760 --> 00:13:42,280
Speaker 1: d C. Last weekend with our Hall County World War

243
00:13:42,320 --> 00:13:45,320
Speaker 1: two veterans to visit their memorial. One of the side

244
00:13:45,320 --> 00:13:47,600
Speaker 1: trips was a visit to the Museum of American History.

245
00:13:48,280 --> 00:13:51,040
Speaker 1: They're on display was the first ether and hailer from

246
00:13:51,800 --> 00:13:54,760
Speaker 1: six with credit given to William Morton as the inventor

247
00:13:54,800 --> 00:13:58,640
Speaker 1: of the device. Because my husband isn't an aesthetist, I

248
00:13:58,679 --> 00:14:01,360
Speaker 1: took an interest in the display and snapped a picture.

249
00:14:01,960 --> 00:14:05,839
Speaker 1: No mention of Horace Wells. Oh goodness, so the gas

250
00:14:05,920 --> 00:14:09,240
Speaker 1: lars continued to gasloors go on and on. We also

251
00:14:09,320 --> 00:14:12,640
Speaker 1: got another email from Frank and I know we've gotten

252
00:14:12,720 --> 00:14:15,080
Speaker 1: dental stories from you guys in the past, but this

253
00:14:15,120 --> 00:14:18,440
Speaker 1: one really applied after that Horace Wells episode, since he

254
00:14:18,559 --> 00:14:20,760
Speaker 1: was in fact a dentist. So Frank wrote us to

255
00:14:20,800 --> 00:14:24,280
Speaker 1: say that my parents started seeing Dr Silver when my

256
00:14:24,320 --> 00:14:26,840
Speaker 1: older sister was born. He had a brand new office

257
00:14:26,880 --> 00:14:29,640
Speaker 1: and the latest equipment when he was still in practice.

258
00:14:29,680 --> 00:14:32,400
Speaker 1: The local paper ran a story about his fifty years

259
00:14:32,440 --> 00:14:34,600
Speaker 1: as a dentist. He had served in World War Two

260
00:14:35,160 --> 00:14:37,200
Speaker 1: after hearing the dental drill. For as long as I

261
00:14:37,240 --> 00:14:39,920
Speaker 1: could remember, but having good check ups. I had ten

262
00:14:40,000 --> 00:14:42,680
Speaker 1: cavities and fillings from the time I was about fourteen

263
00:14:42,840 --> 00:14:45,280
Speaker 1: until I was in college, so from the mid nineteen

264
00:14:45,320 --> 00:14:49,200
Speaker 1: eighties until the early nineteen nineties. He never asked me

265
00:14:49,240 --> 00:14:52,000
Speaker 1: if I wanted no vacine. I didn't know I could ask.

266
00:14:52,120 --> 00:14:55,200
Speaker 1: I thought it was for quote, real pain. My parents

267
00:14:55,240 --> 00:14:57,760
Speaker 1: never asked me if I had taken any painkillers, and

268
00:14:57,880 --> 00:15:01,400
Speaker 1: never offered any after the fact. I quote got through

269
00:15:01,480 --> 00:15:05,480
Speaker 1: by imagining really cold ice cream. This is kind of

270
00:15:05,560 --> 00:15:08,280
Speaker 1: a very bad email, but funny too. I'm sorry you

271
00:15:08,280 --> 00:15:10,960
Speaker 1: had to get through through all of that, Frank, but

272
00:15:11,120 --> 00:15:13,760
Speaker 1: I guess you could really identify to some of the

273
00:15:13,800 --> 00:15:16,560
Speaker 1: people we were discussing in that podcast. Yeah, on the

274
00:15:16,560 --> 00:15:18,520
Speaker 1: bright side, you never had to go through that whole

275
00:15:18,680 --> 00:15:23,240
Speaker 1: numbing sensation. I think that's probably preferable obviously to the day.

276
00:15:23,440 --> 00:15:25,400
Speaker 1: You're right. You're right, that's not a bright side. But

277
00:15:25,560 --> 00:15:28,040
Speaker 1: thanks for writing in and sharing your story. If anyone

278
00:15:28,080 --> 00:15:31,160
Speaker 1: else has any related stories that they would like to share,
