A Denver, Colo., native, Richard followed his lifelong love of music at Princeton, eventually earning a Ph.D. from that department in 1978. He played lead guitar in the rock band Chappaqua (comprised of six fellow Princetonians) that performed at numerous club functions and several Class of 1972 reunions.

He was a member of the U.S. Chess Federation, the American Go Association, and the Recording Industry Associates of America.
