Trivia time: what was the name of Anoop Gupta's brother?

Anoop Gupta developed a Prolog implementation for the TI Explorer Lisp machine in the 1980's. I used to know his brother's name (I think of all sorts of goofy things and then try to remember or find the answer). In the latter part of the 1980's, I was doing Defense-related AI work, so I got to talk some interesting people were still involved. By 1990, all that had collapsed. The main thing that I had gotten out of it was a good library of books and papers. Many of the books were recommended to me and the rest I just bought, because I was buying every AI book in sight. I also have copies of a lot of great papers, such as David H. D. Warren's thesis about compiling Prolog and Carl Hewitt's thesis from MIT. I have some off-beat things, such as the Rosie Manual.
