[4][5] Rosenberg moved to the United States as a young man and rose to become an assistant to Emanuel Sacks, vice president of entertainment at NBC.
He was fired during a year of recovery after, sitting in a parked car, he had been hit by a runaway truck: he had to work as a night clerk in a bookstore.
[4][6][7] His other television credits included the 1950s U.S. educational TV series Omnibus[5] and the short-lived 1970s sitcom Husbands, Wives & Lovers, which was created by his wife, Joan Rivers.
[4][5][9] Rosenberg married actress, comedian and commentator Joan Rivers in July 1965, five days after hiring her to work with him in Jamaica rewriting a screenplay for a joint movie deal with his friend Peter Sellers.
In August 1987, several months after Fox fired him and Rivers, Rosenberg died by suicide, overdosing on prescription drugs in a Philadelphia hotel room.
