William Channing Whitney Collection
Starting in 1885, Whitney began his own practice and soon became one of the Twin Cities’ most fashionable residential architects, designing homes for William Dunwoody (1905), Frank Heffelfinger (1902), and Thomas Irvine (1910-1911); the Irvine house is now the Governor’s Mansion in St. Paul. Whitney was a member of the American Institute of Architects, the Minneapolis Society of Fine Arts and a strong proponent of city parks and beautification. His office was a training center for many young architects, such as C.B. Chapman, Adam L. Dorr, and Serenus Colburn. William Whitney died on August 23, 1945.
