William Butts Ittner (September 4, 1864 – 1936) was an American architect in St. Louis, Missouri. He designed over 430 school buildings in Missouri and other areas, was president of the St. Louis Chapter of the American Institute of Architects from 1893 to 1895, was awarded an honorary degree by the University of Missouri in 1930, served as president of the Architectural League of America during 1903–04, and at the time of his death was president of the St. Louis Plaza Commission, a fellow and life member of the American Institute of Architects, and a thirty-third degree Mason. He was described as the most influential man in school architecture in the United States and has a star on the St. Louis Walk of Fame. He was appointed St. Louis School Board commissioner in 1897 and is said to have designed open buildings that featured "natural lighting, inviting exteriors, and classrooms tailored to specific needs." In 1936, Ittner died.

Background

His parents were Anthony F. and Mary Butts Ittner. His father worked at a lead plant and then as a bricklayer before founding Ittner Bros. with his brother Conrad in 1859. William Ittner's father (later a U.S. Congressman) helped establish the trade school from which his son graduated in 1884 "with the first class granted diplomas by Washington University's Manual Training School." He also graduated with a degree in architecture from Cornell University College of Architecture, Art, and Planning, traveled in Europe and married Lottie Crane Allen in St. Louis. He worked in the office of Eames & Young between 1889 and 1891, then practiced alone "before entering brief partnerships, first with William Foster and then with T. C. Link and Alfred Rosenheim." He was elected to the new office of Commissioner of School Buildings for the School Board of St. Louis in 1897 and remained in the position until he resigned in 1910. He continued as "consulting architect" to the Board until October 1914. His first school design was Eliot School (1898–99) and his last was Bryan Mullanphy (1914–15). He is credited with the design of over 430 schools nationwide and has over 35 buildings on the National Register of Historic Places. E-shaped schools were said to be his trademark.
