Both Collis Hardenbergh and Karl Humphrey came to Minnesota in the 1930s and worked as draftsmen for McEnary & Krafft, Minneapolis. Hardenbergh was born in Kansas City, MO, 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.

Humphrey was born in El Reno, OK, 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.

The collection comprises floor plans, elevations and details for more than 150 prestigious residences, many of them in the Lake Minnetonka and Wayzata areas. Clients represented include John Andrus, Dewalt Ankeny, James Ford Bell, Judson Bemis, Karl Humphrey, Collis Hardenbergh, and James Cargill.
