Bert Green was an British-American animator and cartoonist. He was born in 1885 in England, but moved to the U.S. as a child. He studied art at the Pratt Institute and Chase Art School. He became a cartoonist for several newspapers in New York, including the New York Herald, The World, The New York American, The New York Journal and, outside N.Y., The Atlanta Georgian. Later on, he became art department manager on the Chicago Examiner in 1914. Around 1915, he did a daily strip called 'Stella and Gertie'. In 1916 Green became one of the earliest animators and scriptwriters working for Hearst International Film Service, a company produced by newspaper tycoon William Randolph Hearst. Green animated, among others on adaptations of Rudolph Dirks' 'The Katzenjammer Kids' and Frederick Burr Opper's 'And Her Name Was Maud'. After the studio closed, Green created the kid-gang comic strip 'Kids' for the Chicago Tribune in 1918, which lasted throughout the 1920s.

Green 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.
