Robert E. Costello, a pioneering producer of classic ’50s television shows who later won a Peabody Award for the PBS series “The Adams Chronicles” and two Emmys for ABC’s daytime serial “Ryan’s Hope,” died of a heart attack on May 30 at his summer house in Amagansett’s Beach Hampton neighborhood. He was 93 and had been diagnosed many years before with chronic obstructive pulmonary disease.
