"He died at home, peaceful, in his sleep at 5:21 a.m. today. [He was] a very brave guy who knew what he wanted, and he wanted to be at home," Constance Johnson tells ABC News.

Johnson was a World War II veteran who acted in shows such as "The Adventures of Superman," "Alfred Hitchcock Presents" and "The Twilight Zone." His last credited role is a 1997 guest spot on the animated series "Meego" as "The Professor."

"My 2 favorite people are now gone," writes Johnson's costar Dawn Wells, who played Mary Ann, on her Facebook page. "The Professor [passed] away this morning. My heart is broken." Bob Denver, who played Gilligan, died in 2005.

Wells also posted a vintage photo of Johnson, which you can see below:
