Bert Green was an animator and cartoonist, born in England, but raised in the USA. After art school, he became a cartoonist for New York papers. Later on, he became art department manager on the Chicago Examiner in 1914. Around 1915, he did a dail strip called 'Stella and Gertie'. Green became one of the earliest animators and scriptwriters of the Hearst International Film Service in 1916, working among others on 'The Katzenjammer Kids'. After the closing of the studio, Green created the kid-gang comic strip 'Kids' for the Chicago Tribune in 1918, which lasted through the 1920s.
He was also affiliated with the Vocafilm Corporation, doing training cartoons for the US Navy during World War I. He wrote articles and stories for Liberty, the Saturday Evening Post and others, mostly illustrated by himself. During World War II, he served at the US Coast Guard. After the War, he returned to cartooning, doing comic book art for 'The Hangman' (Archie) and 'Kids is Kids' (in Humdinger, by Novelty). He died in a veterans hospital in 1948.
