Harrison was born in Talladega in on March 18, 1900. His father, Groce Harrison, was a sixth-generation physician. Harrison moved the family from Talladega to Birmingham in 1906, where Tinsley did extremely well and was advanced three grades, graduating from high school at age 15. He then spent a year at the Marion Military Institute in Marion, Perry County, and three years at the University of Michigan, where he obtained bachelor's degree in 1919. Harrison then completed medical school at Johns Hopkins University in Baltimore and his internship and first-year residency in Boston at the Peter Bent Brigham Hospital (now Harvard University's Brigham and Women's Hospital). After returning to Hopkins for additional study, Harrison was recruited as a member of the staff at the new Vanderbilt Hospital and Medical School in Nashville, Tennessee, in 1925. He and his new wife, Elizabeth Woodward of Massachusetts, then spent 16 years in Nashville, with a year overseas to study and do research in Austria, England, and Germany. The couple would have five children.

Harrison recruited many notable faculty members to Southwestern and remained in Dallas until 1950, when he returned to Alabama to become the second dean of the Medical College of Alabama at UAB and chair of its department of medicine. It became his fourth new medical school, and his efforts led to its later prominence. He retired in 1970 to become a Distinguished Physician of the U.S. Veterans Administration, where he remained until his death on August 4, 1978.
