Louis Christian Mullgardt (1866-1942) was an American architect associated with the First Bay Tradition.[1] He designed houses in Berkeley, Oakland and other cities; the Court of the Ages at the 1915 Panama–Pacific International Exposition; the San Francisco Juvenile Court and Detention Home; the Durant School in Oakland; and a major renovation of the former M. H. de Young Memorial Museum. He made design proposals for multi-building complexes for downtown Honolulu in 1915 and for Yosemite Valley in 1916. He was hired in 1918 to design the Lou Henry and Herbert Hoover House at Stanford University but was dismissed after prematurely publicizing the assignment without the Hoovers' consent. Mullgardt was a native of Missouri. His earlier years were spent in St. Louis, where he began the study of architecture. Subsequently, he continued his studies at Harvard University. Following this, he went to Chicago, where he began designing. In 1893, he entered private practice in St. Louis. In 1895, he made an extended trip to Europe for further study. In 1902, he was commissioned to go to Manchester, England, and in 1903, to London and Scotland. He moved to San Francisco in 1905 and established a solo office. Mullgardt was active in several organizations of architects and artists. He served as president of the San Francisco Society of Architects, president of the California Society of Etchers, vice-president of the San Francisco Society of Artists, director of the San Francisco Art Association, and Secretary of the Group Jury for Etchings and Engravings of the Panama-Pacific International Exposition.[4] Art historian Robert Judson Clark was the leading expert on Mullgardt until his death in 2011. He wrote the catalog essay on the architect for a 1966 exhibition at the University of California, Santa Barbara and the M.H. de Young Memorial Museum Less
