Biographical Note

Both Collis Hardenbergh and Karl Humphrey came to Minnesota in the 1930s and worked as draftsmen for McEnary & Krafft, Minneapolis before forming their own architectural firm in 1947.

Collis Hardenbergh was born in Kansas City, Missouri on May 21, 1912, graduated from Harvard College in 1933 and the University of Minnesota in 1937. From 1935 through 1946 he was employed by several New York and Minneapolis architectural firms. He died in Minneapolis in 1978.

Karl Humphrey was born in El Reno, Oklahoma on January 25, 1914, and graduated from Yale University in 1935 with a degree in architecture. In 1938, he graduated from the same institution with a degree in fine arts. From 1939 to 1941, he was in the office of McEnary & Krafft in Minneapolis, then practiced alone until about 1947 when he joined Hardenbergh in partnership. The firm specialized in the design of single family residences, many of them in the Lake Minnetonka area west of Minneapolis. Humphrey died in 1974, after which Hardenbergh maintained the practice until his death four years later.
