The connections, specifically S-Duality, T-Duality, and U-Duality, were all known prior to Edward Witten,* but it was he, who, nonetheless, posited that the connections were the result of there being some underlying theory to which the 5 string theories were all approximations.

It is noted for expanding upon the 10 dimensional limit of string theory to 11 dimensions to account for supergravity. FTP, what is this theory, which united quantum mechanics with general relativity.
