Ivan Yakovlevych Horbachevsky (1854, Zarubinsky village, Ternopil region – 1942, Prague) was a Ukrainian biochemist, chemist, epidemiologist and hygienist, thermographer.
Horbachevsky studied medicine at the University of Vienna. As a student, he was engaged in scientific and social activities and took the first steps in the study of medical chemistry. Together with M. Drahomanov, he was a head of the student society “Січ” (eng. “Sich”). Ivan Horbachevsky became the first person in the world to synthesize uric acid, revealing the causes and ways of its formation.
Ivan Horbachevsky also managed to work in Prague: starting in 1883, he held the positions of “extraordinary professor” of medical chemistry, dean and rector of the medical faculty. He was also the discoverer of the enzyme xanthine oxidase (1888).
Horbachevsky was awarded the Order of the Iron Crown in 1898, the highest honor of Austria-Hungary. The scientist had such a high level of respect and authority in the Czech Republic that he was elected as a member of the Sanitary Council of the Czech Kingdom.

The Ukrainian has worked extensively in the fields of forensic medicine, hygiene, epidemiology, general chemistry and even toxicology, having written 66 scientific publications in these fields. There are also more that 100 scientific papers in the field of sanitation, most of which took place in Austria-Hungary.
