He started as producer on the PATTY DUKE SHOW, was recommended to Dan Curtis to produce DS, and along the way also produced STRANGE PARADISE (a goth/horror soap similar to DS), the afore-mentioned, highly-regarded (and award-winning) PBS drama series about John Adams's family tree, as well as his Emmy-winning work on RYAN'S HOPE, and ANOTHER WORLD.
Working on DARK SHADOWS also brought him his long-standing third marriage to Sybil Weinberger, the program's music director.
Mr. Costello was 93.
