Trapper John McIntyre

Trapper John McIntyre, also known as John Francis Xavier McIntyre, is a character in Richard Hooker's novel M*A*S*H.

"The only man who ever took a piece in the ladies' can of a Boston & Maine train", McIntyre was depicted by

• Elliott Gould in the film M*A*S*H,
• Wayne Rogers in the television series M*A*S*H, and
• Pernell Roberts in the television series Trapper John, M.D.

In the period between the two television series, the character matured considerably, becoming a more sedate part of the medical establishment. Much of the story line of Trapper John M.D. revolves around the relationship between the Korean War veteran Trapper John and Dr. George "Gonzo" Gates, who had served in a MASH unit in Vietnam and exhibited some of the personality traits Trapper John had had when he was younger.
