Electricity was believed to be a "magical wonder" for many years of its early known existence. It was first produced by electrostatic machines and later by early batteries such as Volta's voltaic pile. However, very little was actually known about the phenomena and little to none of its qualities were used in practical applications until the late 1800s.

 

 

The earliest demonstrations of electricity included electrocuting dead and live animals and eventually people. Luigi Aldini, Bologna, was one of the first to find a correlation between muscular movements and electricity. He found that by "applying sparks to a dead frogs legs" he could make it twitch. Luigi's nephew, Giovanni Aldini, took this concept further by performing public demonstrations of electrocuting human body parts and large animals. Observers were amazed and frightened by the sight of severed limbs and dead animals suddenly jerking frantically as if they were alive and in some frenzied state. As a result of scientist and physicists ability to create such an unknown force, they were often regarded as magicians or wizards.

Louis Figuier, of the  depects how experiments conducted on humans created both a sense of wonder and horror in “Le docteur Ure galvanisant le corps de l’assassin Clydsdale” (1867)

 

The demonstrations grew more shocking and grotesque over time. Giovanni eventually was given the body of a recently executed convict for use in one demonstration. Given the unique opportunity he applied as much electrical energy as possible to the body. The body twisted and jerked wildly, the face created exhilarating and frightening expressions, and the legs and arms moved so much that spectators insisted he must be executed again. This event undoubtedly inspired  the Mary Shelley's novel of Frankenstein. The event was disturbing and inhumane, yet worse was to come.  

 

 

During the war, of the currents in the late 1800s Edison was trying to find ways to popularize his direct current system. On the other hand, George Westinghouse was trying to commercialize Nikola Tesla's AC distribution system. As a result, Edison decided to demonstrate the dangers of alternating current to the press and public by killing animals such as cats, dogs, and unwanted cattle. Additionally, he tried to popularize a phrase for being electrocuted by AC as being “Westinghoused.”

 

 

The worst of the battle came when a prisoner, William Kemmler, was sentenced to be the first put to death by electricity. Edison's company built the first electric chair and using AC electricity planned to put the prisoner to death painlessly. However, The first attempt only caused unconsciousness and did not stop the heart. After the generators recharged, they tried a second time with a higher voltage, this time still not killing the man but burning his skin where the electrodes were attached and slowly burning his insides. It took over eight minutes for the man to be executed. After the event, Westinghouse declared they would have been better off with an ax.

 

Only a short time after the de-mystifying (or de-demonizing) of electricity, the world got its first Electrical Engineering college. What was once feared was bent to our will.

(via AT&T)

 

It is easy to forget that there was a time when data communication was vastly an unknown and abstract topic. A relic of the start of this digital era was found in the AT&T archives. It was recently released so that those who were not around to experience the paradigm shift, could at least marvel at the primitive history that was robotics in the 1960’s.

 

 

Jim Henson, a movie director who eventually would work on Sesame Street and the Muppets, created a short film of a little industrial robot to reify the concept of data transfers and communication to business people attending Bell System’s, Bell Business Communication Seminar.

 

 

Ted Mills of AT&T, at the time, sent Henson a memo describing the concept he wanted for the film. It read, "He [the robot] is sure that All Men Basically Want to Play Golf, and not run businesses — if he can do it better." Henson went a little deeper.

 

 

In the short film, titled "Robot," Henson communicates the immense potential of computerized systems in a slightly dark comedic tone surely to intrigue any one attending the seminar. The robot explains its affinity for “digesting vast oceans of information” as well as its contempt for emotional humans, which, in its view, serve little purpose for the new robotic race.

 

 

Apart from its technological hubris, the robot explains that his potential is shortened by man’s incompetent imperfect design. I wonder if the message resonated among ambitious business folk, of the day. It was only the beginning of our industrial exploit of a digital age. Luckily, it did not turn out to be a robot controlled dystopian future.

 

Element14 User Jim Hayden suggested another Jim Henson - AT&T gem. I find it interesting that the AT&T hierarchy of the time felt that puppets were the only way to get CEO accustomed to computerized technology. I suppose it worked. See below:

Lamarr, Hedy_03.jpg

Major technology contributions and motion picture acting rarely go hand-in-hand in someone's career path, but screen actor Hedy Lamarr pulled it off and gave the world the earliest form of spread spectrum communication.


In 1933, Lamarr married Fruedrich Mandl a Vienna-based arms manufacturer. Mandl kept her from pursuing much in life. The controlling nature of the marriage found her either locked up in castle Schwarzenau or at Mandl's side. He would bring her to meetings with arms clients, military leaders, and technology talks. In which she learned about issues with guiding torpedoes via radio while protecting against jamming. In the autobiography 'Ecstacy and Me," parties hosted by Mandl had Benito Mussolini and Adolf Hitler as guests. She had to escape.


Reports offer a few ways in which she escaped Mandl. One has her disguising herself as a maid. The other is a far more movie-like  plot. She asked Mandl is she could dress in all of her expensive jewelry for an up-and-coming  party. At which, she drugged Mandl and escaped covered in the riches. Either way, she escaped to Paris in 1937. She promptly filed for divorce and moved to London. 


Louis B. Mayer, a film producer, hired Lamarr. At the time Lamarr was going by her original name Hedwig Eva Maria Kiesler. Mayer insisted she change her name to Hedy Lamarr, in homage to the silent era actress Barbara LaMarr, who died from an overdose in 1926. (As for actor's lives, I see not much has changed.)


Later in life, Lamarr met composer George Antheil at a dinner in Hollywood. Antheil is famous for his cacophonous 'Ballet Mécanique' and the open-top pianola that could teach keyboard techniques. How it came to the subject of torpedoes; no one will ever know, but the conversation steered in that direction. Together they developed an early form of spread spectrum wireless communication.


Lamarr said that wireless communication could be protected from jamming by varying the frequency of transmission. In the duo's design, the communication system would switch between 88 different frequencies unpredictably. The idea was to make sure the enemy has no idea which frequency to block. Antheil contributed coordinating the transmitter and receiver by controlling a switch that would move different channels in two piano rolls running at the same speed. Soon after, US Patent 2,292,387 was granted to the pair on June 10, 1941 under the name "Secret Communication System." Unfortunately, the pair never earned a dollar from the effort.

Antheil died in 1959 never to see the ultimate value of his thoughts.

Later, in 1962, the idea was used in military warships during the blockade of Cuba. The patent was expired by that time.


The idea was forgotten until 1997 when the Electronic Frontier Foundation gave an award to Lamarr for the contribution. Following in 1998, Wi-LAN inc "acquired a 49 percent claim to the patent from Lamarr for an undisclosed amount of stock," but since it was expired, no money may have actually exchanged hands. However, it was a dignified gesture to honor the early creators.


Although Lamarr was never able to directly help in military efforts during WWII. She wanted to join the National Inventors Council, but was told she could do more for the effort by selling bonds. She followed their suggestion, and during one such fund raiser event, she sold $7 million in bonds. (Which is $791 million in 2011 dollars, adjusted for inflation.)


Unfortunately, Lamarr passed away on January 19, 2000, but her legacy lives on. The concept is now part of everyday life. The concept keeps all out wireless communications, be it cell phones or WiFi, from interfering with each other. Next time you make a call remember, you are using a "Secret Communication System."
