Leo Cullum, American soldier, pilot, and cartoonist (d. 2010)
Leo Aloysius Cullum (January 11, 1942 – October 23, 2010) was an American cartoonist, one of the more frequent contributors to The New Yorker with more than 800 gag cartoons published. He started his drawing career after having served as a pilot in the United States Marine Corps during the Vietnam War and flying planes commercially for Trans World Airlines and American Airlines.

Born in Newark, New Jersey, Cullum was raised in North Bergen, New Jersey and earned his undergraduate degree in 1963 from the College of the Holy Cross, where he majored in English. He joined the United States Marine Corps after graduating from college, earning a commission as a second Lieutenant. Upon completion of his flight training in Pensacola, Florida, Cullum deployed to Vietnam, where he flew more than 200 missions, mostly ground attacks in support of the infantry in addition to attacks on the Viet Cong supply lines on the Ho Chi Minh trail in Laos. Though the missions over Laos were not officially acknowledged, Cullum was baffled by the need for secrecy, saying "the North Vietnamese certainly knew it wasn't the Swiss bombing them".
