pretty sure you mean Ed Thorpe, though Thorpe did eventually collaborate with Shannon.

According to Thorp himself they were collaborators on the roulette scheme.

“The first wearable computer was conceived in 1955 by the author to predict roulette, culminating in a joint effort at M.I.T. with Claude Shannon in 1960-61. The final operating version was tested in Shannon’s basement home lab in June of 1961. […] The Shannons and Thorps tested the computer in Las Vegas in the summer of 1961.”

Also, there is J. Doyne Farmer [1], who was part of a group that used computers in their shoes, early 1980s, to "game" roulette tables in Los Vegas. Story is told in Thomas Bass's interesting book, "The Eudaemonic Pie". [2]

The full story of the invention of the first wearable computer is told in Ed Thorp's memoir https://www.amazon.com/gp/aw/d/B00SEFEYCI/

Highly recommended!
