Reed died on May 12, 1992, at the age of 59, in Pasadena, California. Initially attributed to colon cancer, his death was later revealed to have been hastened by AIDS. Reed was survived by his daughter, Karen Baldwin, from a short-lived marriage in the 1950s. As a gay man, Reed had struggled to hide his sexuality during his Hollywood years. "He was an unhappy person," Florence Henderson said. "I think had Bob not been forced to live this double life, I think it would have dissipated a lot of that anger and frustration."
