Charles C. Hartmann

Charles C. Hartmann (1889 – December 31, 1977) was an American architect in practice in Greensboro, North Carolina, from 1921 until his retirement in 1966.

Early life and professional career Charles Conrad Hartmann was born in 1889 in New York City to Swiss-German parents. In 1905 he became an apprentice in the office of Warren & Wetmore and in 1907 was employed as a draftsman by Charles E. Birge. He was educated in design in an atelier affiliated with the Beaux-Arts Institute of Design and as a special student at the Massachusetts Institute of Technology.

In 1913 he returned to New York to work for William Lee Stoddart, a noted architect of hotels. During his time with the Stoddart firm Hartmann would rise to the level of associate partner. Immediately after World War I he began to visit North Carolina to supervise construction of two Stoddart-designed hotels, the O. Henry (1919, demolished) in Greensboro and the Sheraton (1921) in High Point. In Greensboro Hartmann developed contacts with the local business community and in 1921 executives of the Jefferson Standard Life Insurance Company invited Hartmann to design the company's new headquarters on the condition he establish himself in Greensboro. The resulting Jefferson Standard Building (1923, NRHP-listed) established Hartmann as a leading member of Greensboro's small architectural community. He became well known for the design of tall commercial buildings in communities throughout North Carolina and for homes for the businessmen that commissioned them.

Hartmann's employees included Edward Lowenstein.
