Lowther was born in Houston, Texas, to Alexander Carswell Lowther and the former Jeanette Pippin. In 1931, he moved with his family to Alexandria in Rapides Parish. He was reared on 13th Street in Alexandria. He and a brother, Buster, and best friend, Ace Higgins, staged mock track meets, which set the stage for his later demonstrations of athletic prowess. He graduated in 1941, while he was still seventeen, from Bolton High School in Alexandria. At LSU, he majored in English and was a member of the Sigma Alpha Epsilon fraternity. His education at LSU was interrupted by World War II. In 1943 and 1944, he was a United States Army Air ForcesB-17 bomber pilot with the rank of lieutenant.
Athletic career
Because he averaged fifteen points per game as a forward at LSU, Lowther was named to the Helms Athletic Foundation All-America basketball team. He also finished in second and fourth places, respectively, in the javelin and pole vault in the National Collegiate Athletic Association championships. On the occasion in 1995 of his induction into the Louisiana Sports Hall of Fame in Natchitoches, Lowther told The Alexandria Town Talk that his winning in javelin and pole vault was unusual because most athletes can excel at only one of the two competitions. Heavier athletes have an advantage with the javelin, and slimmer ones with the pole vault. He was 6'5" and weighed 185 pounds. Upon Lowther's death of a lengthy illness in Alexandria at the age of ninety-one, his long-time friend Frank S. Brian of Baton Rouge became the lone survivor of the original five starting LSU players in the consecutive winning teams from 1945 to 1947. LSU had its best winning percentage in those two seasons. The Tigers won fifty-three of sixty-four games when Lowther was on the court. In 1946, Lowther and four players from the Kentucky Wildcats were named to the five-man All-Southeastern Conference men's basketball first team. In another 1946 triumph, Lowther was named the triple-jump champion at the national Amateur Athletic Union competition. In 1947, he was voted "Best All-Around Athlete" at LSU, having prevailed over Y. A. Tittle, Al Dark, and Joe Adcock. In 1978, he was inducted into the LSU Athletic Hall of Fame. He was also a member of the LSU chapter of the National "L"etterman Club. In 2005, after surviving lung and brain cancer, Lowther was honored as a Southeastern Conference "Living Legend" for his basketball prowess. Lowther placed third in the 1946 AAU decathlon and would have competed in the Olympics had he not broken a leg at an SEC meet in Birmingham, Alabama. He was still seeded in 1948 ahead of Bob Mathias of California, the Olympic champion in the trials who competed in 1948 and 1952. Lowther could not compete because his leg had yet to heal. For several years, Lowther played professional basketball for the Tri-Cities Blackhawks, now the Atlanta Hawks in Atlanta, Georgia, and the defunct Waterloo Hawks in Waterloo, Iowa.
Later years
Lowther was a businessman and an inventor of fishing lures and board games. While in his seventies, he worked with youngsters at numerous area high schools and Louisiana College in Pineville to demonstrate his knowledge of athletics.
