Donald Arthur Schollander (born April 30, 1946) is an American former competition swimmer, Olympic champion, and former world record-holder. He won a total of five gold medals and one silver medal at the 1964 and 1968 Summer Olympics. With four gold medals, he was the most successful athlete at the 1964 Olympics.

Early career 
Schollander was born in Charlotte, North Carolina, and learned competitive swimming from his uncle, Newt Perry, who ran a swim school in Florida. As a boy, Schollander moved with his family to Lake Oswego, Oregon. Although his first sporting passion was football, he was too small to compete in high school football. Instead, he joined Lake Oswego High School's swim team, and in 1960, helped lead the team to an Oregon state swimming championship as a freshman.

Olympics 
As a teenager in 1962, Schollander moved to Santa Clara, California to train under swim coach George Haines of the Santa Clara Swim Club. Two years later at the age of 18, he won three freestyle events at the AAU national championships. He made the U.S. Olympic team in two individual events and two relays. Months later, he won four gold medals and set three world records at the 1964 Summer Olympics, at the time the most medals won by an American sinceJesse Owens in 1936. 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. He was also named ABC'sWide World of Sports Athlete of the Year.

Schollander appeared on an episode of To Tell the Truth immediately after winning his four gold medals.

College and Olympic swimming 
Schollander attended Yale University and is a member of the Skull and Bones secret society and the Delta Kappa Epsilon (Phi chapter) fraternity along with the future President George W. Bush. He was the captain of Yale's swim team, winning three individual NCAA championships. Schollander returned to the Olympics in 1968, winning the gold medal in the 4×200 meter freestyle relay, but finishing second in the 200 meter freestyle, the event that Schollander had considered to be his best. This was the first Olympics in which 200 meter swimming events were part of the competition.

Following the 1968 Olympics, Don Schollander retired from competitive swimming.

After swimming 
Schollander was inducted into the International Swimming Hall of Fame in 1965, at the age of 19. In 1983, he was one of the first group of inductees into the U.S. Olympic Hall of Fame. He is also a member of Oregon Sports Hall of Fame.

In 1971, he published his first book, Deep Water (ISBN 0720705428, with Duke Savage) chronicling his swimming, his teammates and coaches, and the behind-the-scenes politics of international swimming, especially the Olympic Games. He followed this book in 1974 with Inside Swimming (ISBN 0809289059, with Joel H. Cohen).
