Murphy began his collaboration on Prince Valiant with creator Hal Foster in 1970 when Foster decided to lessen his workload at age 78. With Foster's retirement in 1979, Murphy's son Cullen took over the writing. Cullen Murphy began contributing stories to Foster while studying at Amherst College. Murphy continued to draw Prince Valiant with his son scripting and his daughter doing the lettering and coloring. He retired in March 2004, turning the strip over to his chosen successor, illustrator Gary Gianni. Murphy died four months later in Cos Cob, Connecticut.
