Jeff Wald, a manager for Helen Reddy, Sylvester Stallone and George Carlin, died Friday at 77. No cause of death was revealed by his daughter, Traci Wald.

“To the very end, he was laughing and fighting for the life he lived with epic proportions in every way,” Traci Wald said in a statement. “He was surrounded by the family he loved so much and the music that was the soundtrack to his life of eternal optimism. We are heartbroken by the loss of our husband, father, friend and fierce advocate for women’s rights and justice for all.”

Born as Jeffrey Sommers in 1944, Wald moved to Los Angeles and formed a company with George Carlin and The Turtles on its roster. He then signed a deal with Capitol Records in a deal tied to Reddy. Wald was married to the actress and singer and worked as her manager throughout their 18-year marriage.
