Adolf Hempt (1874–1943) was a Serbian biologist and the founder of the Pasteur Institute in Novi Sad, Serbia. He stabilized Pasteur's vaccine against rabies so that it could be distributed to distant places. His method of producing vaccines were used in all Central European countries, and vaccine against rabies was produced according to his technology until 1989. Biography Hempt was born on September 21, 1874 in Novi Sad (then under the Austro-Hungarian monarchy) as son of a Belgian Protestant missionary and Katarina Tewely, originally from Budapest. The family soon moved to Sarajevo where he finished his primary studies. As the family was not enough wealthy for paying his studies he started studying medicine in Graz and Munich as military medic. Henry earned his medical diploma on the University of Graz in 1898. As an aspiring medic, he started working in the same year in Vienna in the First Garrison Hospital. After that, he was moved to a cavalry garrison next to Vienna. During this, he married Maria Winkler in 1903. His first son was also born here in 1904. After demobilization, they moved to Lukavac, where ha worked as a doctor. In Bosnia, he gained experience in trying to heal different diseases including rabies. In that time, Pasteur Institutes were established in Belgrade, Budapest and Niš, but most of the people were not traveling to these cities, and the existing vaccination was not transportable. During World War I, he was a commander of a hospital in Trieste. After that, he worked in Bosnia; in 1921, he returned to Novi Sad, accepting the invitation of the Serbian Minister of Health Andrija Štampar. Here, he founded a Pasteur Institute and became the first director of the same. The institute was producing Pasteur's vaccine against rabies, and provided information to the people about prevention. Dr. Hempt published his modifications to the vaccine against rabies in 1925, which was accepted on a medical conference in Paris in 1927. After that, the vaccine was produced according to his technology all around Europe. This so-called inactive or "dead vaccines" were produced in Europe to the end of 1980s, and are still used in India and some developing countries. He died in 1943 in Novi Sad, where he is buried in the old Protestant graveyard. A memorial tablet in his memory was erected in the Pasteur Institute in his remembrance.
