In addition, Thorp, while a professor of mathematics at MIT, met Claude Shannon, and took him and his wife Betty Shannon as partners on weekend forays to Las Vegas to play roulette and blackjack, at which Thorp was very successful. His team's roulette play was the first instance of using a wearable computer in a casino — something which is now illegal, as of May 30, 1985, when the Nevada devices law came into effect as an emergency measure targeting blackjack and roulette devices. The wearable computer was co-developed with Claude Shannon between 1960–61. It relied on a pair of operators, where one would watch the wheel and use his toe to input the cadence of the wheel, and the other would receive a message in the form of musical tones through a hidden earpiece. By betting on groups of neighboring numbers on the wheel they could gain a sufficient advantage to make a profit. The final operating version of the device was tested in Shannon's home lab at his basement in June 1961. Based on his achievements, Thorp was an inaugural member of the Blackjack Hall of Fame.
