Family representative Harlan Boll says Johnson died early Wednesday of heart failure following a three-year battle with bladder and prostate cancer. No services have been planned, but his ashes will be spread in a private ceremony.

One of his characters was Wolfgang, a cigarette-smoking German soldier who thought World War II was still going on.

Johnson’s other television appearances include “Bewitched,” ”The Partridge Family,” ”Lost in Space” and “The Donna Reed Show.”
