Sebring spent twenty-two months overseas and thirteen months in combat during World War I, and was twice decorated by the U.S. Army with the Silver Star for exceptional bravery under enemy fire, and also received the Croix de Guerre and Corde de Fourragere from the French government. Sebring was honorably discharged from the Army as a sergeant in 1919.
While playing football at Kansas State, one of Sebring's coaches was Captain James Van Fleet, a U.S. Army officer who was one of the college's Reserve Officer Training Corps instructors. Van Fleet joined the faculty at the University of Florida in Gainesville, Florida in 1921, and also became an assistant coach for the Florida Gators football team. When Van Fleet became the head coach of the Gators in 1923, he asked Sebring to join him in Gainesville as an assistant football coach and the head coach of the Florida Gators track and field and boxing teams. Sebring accepted the coaching position and also enrolled in the University of Florida College of Law as a student. When the Army transferred Van Fleet to a new posting in the Panama Canal Zone after the 1924 season, he recommended Sebring as his replacement, after serving as Van Fleet's chief scout in 1924. Sebring quickly proved himself to be a creative football coach and innovator; his 1925 Gators finished with an 8–2 record, the best record in school history to that time. Florida went 7–3 in 1927, Sebring's third and final season, and the team he recruited for 1928 finished 8–1 and led the nation in scoring. Sebring graduated with a bachelor of lawsdegree in 1928, and was later inducted into the University of Florida Athletic Hall of Fame as an "Honorary Letter Winner" and was tapped into Florida Blue Key leadership society.
Lawyer and judge
After receiving his law degree, Sebring practiced law in Miami and Jacksonville, Florida. He was appointed judge for the Eight Judicial Circuit from 1933 to 1943 and served on the Florida Supreme Court from 1943 to 1955. After World War II, President Harry S. Truman appointed Sebring to sit on the bench for the Nuremberg Trials of Nazi war criminals, along with Walter B. Beals, Johnson T. Crawford, and Victor C. Swearingen. Sebring did not want to resign from the Florida Supreme Court and he was granted a leave of absence; the other justices appointed a new lower-court judge each month to serve in Sebring's place during his absence. While in Nuremberg in 1946 and 1947, Sebring was a judge on the Doctors' Trial, one of the Subsequent Nuremberg Trials. He returned to service on the Florida court, and was later elected chief justice by his colleagues, serving from 1951 to 1953.
On September 1, 1955, Sebring retired from the Florida Supreme Court and was appointed as the dean of Stetson University College of Law, the first dean after the college moved from DeLand to Gulfport, Florida. Sebring was credited with dramatically expanding the student body and faculty, and deepening the quality and diversity of the college's academic courses. Sebring's retirement from Stetson was planned for September 1, 1968, but he died unexpectedly five weeks earlier. In 1976, Stetson named a law school courtroom in his memory; and, in 2004, the college named him as one of the first seventeen members of its hall of fame.
