Pete A. Morisi studied at the Cartoonist & Illustrators School. In 1948 he contributed to crime and historic titles by Fox Features. During the 1950s, he worked on several Marvel war, horror, crime and western titles, like 'Arizona Kid', 'Strange Tales' and 'Rawhide Kid'. His other 1950s credits include work for St. John Publishing, Nesbit Comics, Quality, Toby Press, Harwell Publications, Harvey Comics and Lev Gleason, working mainly on mystery and war titles. He also worked as an assistant on the 'Saint', 'Flash Gordon' and 'Dickie Dare' newspaper strips.
Morisi is perhaps best known as PAM on Charlton's 'Thunderbolt' series in the sixties, which first came out in December 1965. He worked for Charlton since 1957, and contributed to many of the company's titles, like 'The Masked Raider', 'Gunmaster', 'Johnny Dynamite', 'Vengeance Squad' and 'Kid Montana'. Morisi wrote much of his own material. When much of the comic book industry came to its end in the 1950s, Morisi became a NYPD cop. He signed his subsequent comics work, mainoy for Charlton, with his initials, PAM to keep his NYPD supervisors from knowing about his comics work. He retired from the force in 1976 and did his final comics work for Charlton's horror titles in the 1980s.
