Clarence Shepard Day Jr. (November 18, 1874 – December 28, 1935) was an American author and cartoonist, best known for his 1935 work Life with Father. Early life and family background Day was born in New York City to Clarence Shepard Day Sr. (1844-1927), a stockbroker, and Lavinia (née Stockwell) Day (1852-1929). His grandfather Benjamin Day was the founder in 1833 of the New York Sun. His uncle Benjamin Henry Day Jr. was the inventor of the Ben Day printing process. Day attended St. Paul's School and graduated from Yale University in 1896, where he edited the campus humor magazine The Yale Record. Career In 1897, Day joined the New York Stock Exchange, and became a partner in his father's Wall Street brokerage firm. Day enlisted in the U.S. Navy in 1898, but developed crippling arthritis and spent the remainder of his life as a semi-invalid. Upon mustering out of the Navy, he returned to his business career, but his illness forced him to retire in 1903 and seek to improve his health in Arizona and Colorado. He soon returned to New York City, however, and began publishing the Yale Alumni Weekly and contributing essays and drawings to various publications. Day's most famous work is the autobiographical Life with Father (1935), which detailed humorous episodes in his family's life, centering on his domineering father, during the 1890s in New York City. Scenes from the book, along with its 1932 predecessor God and My Father, and its 1937 sequel Life with Mother, published posthumously, were the basis for the 1939 play by Howard Lindsay and Russel Crouse, which became one of Broadway's longest-running non-musical hits. In 1947—the year the play ended on Broadway—William Powell and Irene Dunne portrayed Day's parents in the film of the same name, which received Oscar nominations for cinematography, art direction, musical score and best actor (Powell). It also became a popular television sitcom, airing from 1953 to 1955. Day was a vocal proponent of giving women the right to vote, and contributed satirical cartoons for U.S. suffrage publications in the 1910s. According to James Moske, an archivist with the New York Public Library, who arranged and cataloged the library's Clarence Day Papers, a survey of Day's early short stories and magazine columns reveals "he was fascinated by the changing roles of men and women in American society as Victorian conceptions of marriage, family, and domestic order
