As a wealthy man, Kellogg built a summer home for his wife and children in Hickory Corners, MI--not far from Kalamazoo--between 1925 and 1926. He was inspired by the Tudor style, which can been not only in the exterior architecture but in the interior woodwork and details as well. Ornate carvings and beautifully detailed woodwork set the mansion apart.
The Kellogg family used the house until in 1942, when the Kelloggs allowed Coast Guard use of the estate for training and induction. Then as WWII came to a close, Percy Jones Hospital used the estate as a rehabilitation center for returning servicemen.
At the age of 91, Will Keith Kellogg passed away on October 6, 1951. According to his will, the estate was then given to Michigan State University, becoming an official part of the Kellogg Biological Station. Today visitors can tour the house and grounds.
