Theodore Eisen (July 10, 1852 - March 14, 1924) was an American architect. He designed many houses in Los Angeles, California.
Theodore Augustus Eisen was born on July 10, 1852 in Cincinnati, Ohio. His father, Augustus Ferdinand Eisen (1824-1870), was a Swedish-born immigrant to the United States. His mother, Babette Eisen, was a Prussian-born immigrant. After living in Ohio, they settled in San Francisco, California, where Theodore grew up.
Eisen became an architect in Los Angeles, California in 1887. He opened a practice with Sumner Hunt in 1895. They designed mansions near Chester Place. In 1892, they designed the Froebel Institute, later known as Casa de Rosas. They also designed several mansions on West Adams Boulevard in the Craftsman and Tudor Revival architectural styles. They planned design the Posey House for Sara Posey and her husband, Oliver Posey, a mining businessman, with touches of Gothic Revival, Moorish Revival and Spanish Revival styles. However, as the Poseys's wealth declined, the project was shelved. Instead, St Vincent's Church was built two decades later, thanks to a gift from the Doheny family.
