He painted two murals in the lobby of the Spring Street Courthouse in Los Angeles: Life on the Old Spanish and American Ranchos in 1938 and Aerodynamism in 1941.[6]
Labaudt was one of a select number of civilian artists invited to join the United States Army Art Program in World War II. He was appointed to the program in April 1943, and assigned to the China Burma India Theater. When the Army's War Art Unit was abruptly eliminated by Congress, he joined the war art program of Life magazine. He left Los Angeles for India in September 1943, traveling for two months aboard a Liberty ship carrying a cargo of dynamite.[7] He was killed in a plane crash in Assam on December 12, 1943, en route to China, where he had been assigned to capture scenes of guerrilla warfare. Labaudt was the first war correspondent killed in that theatre[8] and the only Life artist-correspondent to die in the war. None of his sketches or personal effects survived.[4][9][2][10]
In 1946, Labaudt's widow Marcelle opened the Lucien Labaudt Art Gallery at 1407 Gough Street in San Francisco.[12][11] His work can be seen at the San Francisco Museum of Modern Art.[13]
