Papers of Harold F. Wendel consist of general correspondence; files on the State Sanitary Authority; a file on Wendel's trade mission to Japan; materials related to the University of Oregon; and general biographical materials. Most of the collection relates to Wendel's civic and government activities, with very little on his work as head of the Lipman Wolfe department store. Much of the correspondence is between Wendel and various political figures regarding national and international affairs, including letters to and from Oregon's U.S. senators and representatives, such as Wayne Morse and Edith Green. Also of interest are two photographs of the Lipman Wolfe float in a Portland Rose Festival parade in the late 1920s.
