An excerpt from Armstrong’s book Mary and Lou and Rhoda and Ted, on how Treva Silverman helped create TV’s most memorable characters:

One night in 1964, Silverman was playing at a piano bar in Manhattan’s theater district—it was another one of those dark, smoky places, but this one had a well-tuned baby grand. She took her requisite set break, listening to the glasses clink and the patrons murmur in the absence of her playing. Still energized from her performance, she struck up a conversation with an intense, bearded, hippie-ish guy and his girlfriend sitting near her at the bar. Soon they were chatting about their mutual love of F. Scott Fitzgerald and J. D. Salinger. Beards were only just on the brink of acceptable mainstream grooming at the time, a signal of a certain kind of rebelliousness that endeared this guy to Silverman. Guys with beards tended to smoke weed, be creative, listen to cool music. They were Silverman’s people. Even more so when they could talk Fitzgerald and Salinger. It figured that he was there with a woman, though. Those guys were always taken.

The guy, Jim Brooks, worked at CBS as an assistant in the newsroom.
