and William F. Nolan. As his career progressed, Johnson formed, in the 1960s, a loose, short-lived federation with fellow authors and friends Matheson, Theodore Sturgeon, and others called "The Green Hand". The intent was to leverage their works in the fashion of a union within the Hollywood system for TV production. Unfortunately, the enterprise fell apart after a few months. In his later years, he wrote comic books and was a frequent guest at science fiction and comics conventions. Johnson co-created the comic book series Deepest Dimension Terror Anthology with cartoonist and author Jay Allen Sanford. Personal life Johnson married Lola Brownstein on October 10, 1952, in Los Angeles, and fathered two children, Paul and Judy. He was a vocal advocate for the legalization of marijuana. Along with his writing output, Johnson was instrumental to the early development of San Diego Comic Con. He was also a longtime vegetarian. Death Johnson died on Christmas Day 2015, of bladder and prostate cancer at a Veterans Administration Medical Center hospital in North Hills, California. He is interred at Riverside National Cemetery.
