Fearing retribution, Dr. John Fryer gave a speech at the American Psychiatric Association (APA) convention in 1972 as Dr. [BLANK] Anonymous while wearing a wig and a mask that is sometimes described as Nixon-like.

That impassioned speech would lead the APA to reverse a century-old position and declare a year later that homosexuality was not a mental disorder. What common first name fills in the blank?
