Regarding Grant-Humphreys Mansion. Built in 1902 in a Beaux-Arts style commissioned by James Benton Grant, the third Governor of Colorado, and his wife, the prominent socialite Mary Goodell Grant. In 1917, Mary sold the mansion to another influential and connected family, the Humphreys, best remembered for opening Denvers first airport.
For more than half a century, the Grant-Humphreys Mansion played host to the elegant soirιes of Colorados elite. In 1976, it was bequeathed by Ira Boyd Humphreys to the Colorado Historical Society (now History Colorado), so that future generations of Coloradans could continue to enjoy this setting for their own special occasions.
