Born in Stratford-Ontario, Canada, Thomas P. Hinman moved to Atlanta at a young age. In 1891, he earned his degree in dentistry from the Southern Medical College. Hinman’s reputation in dentistry grew in the areas of education practice; his many accomplishments include the creation of the Atlanta Midwinter Clinic which brought the most important medical and dental authorities to Atlanta. With the same fervor in his practice, he became a notable figure in Atlanta’s civic and business affairs. Dr. Hinman held high offices in many professional organizations including the appointment by President Woodrow Wilson as the U.S. Delegate and Honorary Chairman of the Section VIII of the Fourth International Congress of Dentists in London. This nomination was considered one of the highest tributes in the dental world. He was also the founder of the annual Hinman Dental Conference in Atlanta, that is now over 100 years old.
Hinman's son, Thomas P. Hinman Jr., attended Georgia Tech (class of 1926), and followed in his father into dentistry. After Hinman Sr.’s death, his estate provided funds to complete large renovations to Georgia Tech’s Engineering Experiment Station, now named in his honor. Both father and son were deceased by the time the Hinman building was dedicated in 1951.
