Rudolf Schrader (also spelled Rudolph) (March 17, 1875 – January 18, 1981) was an American gymnast who competed at the 1904 Summer Olympics in St. Louis. As a member of the club he placed seventh in the team all-around and participated in three individual events, his best finish being 68th in the gymnastic triathlon. Born in Germany, Schrader moved to the United States at the age of 15 and worked as a cabinetmaker while training as a gymnast. After the Olympics he joined Sears and remained with them until his retirement at the age of 65. Until he was surpassed by Walter Walsh in March 2013, Schrader was the longest-lived Olympian, having died in January 1981 at the age of 105.
