Walter Paepcke (June 29, 1896 – April 13, 1960) was a U.S. industrialist and philanthropist prominent in the mid-20th century. A longtime executive of the Chicago-based Container Corporation of America, Paepcke is best noted for his founding of the Aspen Institute and the Aspen Skiing Company in the early 1950s, both of which helped transform the town of Aspen, Colorado into an international resort destination and popularize the sport of skiing in the United States.
