Donald Arthur Schollander (born April 30, 1946) is an American former competition swimmer, five-time Olympic champion, and former world record-holder in four events.

[6] His success helped earn him the James E. Sullivan Award as the top amateur athlete in the United States, and the AP Athlete of the Year, defeating runner-up Johnny Unitas by a wide margin.

[citation needed] In his biography, Schollander attributes a temporary decline in his endurance, technique, and speed after the 1964 Olympics as a result of time away from training while he recovered from mononucleosis, the shorter workout distances he swam at Yale as opposed to the distances he swam in high school at Santa Clara under George Haines, the absence of top competitors competing against him while he swam at Yale, and a short bout with Asian Flu.

With the help of George Haines's coaching in Santa Clara in the summer of 1965, Schollander believed he recovered much of his prior speed and endurance.

[8] Schollander attended Yale College and is a member of Skull and Bones, a secret society, and the Delta Kappa Epsilon (Phi chapter) fraternity.

His gold medals are on display to the public at a Bank of America branch location in downtown Lake Oswego.
