at the medical faculties, as well as special courses on the anatomy of the nervous system and analytical chemistry. In 1868 he was confirmed as an extraordinary professor, and in 1870 as an ordinary professor in the department of anatomy. For the preparation of preparations of the human brain, he was twice awarded medals (in 1870 at the All-Russian Manufacturing Exhibition and in 1873 at the World Exhibition in Vienna) and received a very flattering review of them from the famous anatomist Professor Hyrtl. He took an active part in the public life of Kiev. One of the founders of the Kiev Natural Research Society.

Pavlov), until the end of his days Betz worked as the chief physician of the South-Western Railway.


Scientific activity

He was the author of about 50 scientific papers. His main direction of scientific research was anatomy and histology of the central nervous system. In 1874, Betz described giant

of the brain. He developed an original method for making anatomical preparations and collected over 8,000 preparations of human and animal brains. Discovered the chromaffin reaction of the adrenal medulla. Studied embryogenesis and growth of human bones. Director of the Anatomical Theater in Kiev. Full member of the Imperial Natural History Society, Imperial Nature Society, corresponding member of the Paris Anthropological Society, authorized member of the Leipzig Ethnographic Museum. Vladimir Betz was an unsurpassed master of making anatomical preparations. Under a microscope, he made the thinnest cuts into the cells. For a collection of brain preparations, which was exhibited in St. Petersburg in 1870, he was awarded a silver medal. The unique collection was valued at 7,000 Austrian guilders, but the owner categorically refused to sell it, and later donated it to Kiev University.


Awards

Brain tissue preparations made by Betz were awarded medals twice – at the All-Russian manufacturing exhibition in 1870 and at Vienna World Exposition of 1873.Betz W. (1874) ''Anatomischer Nachweis zweier Gehirncentra.'' Centralblatt für die medizinischen Wissenschaften. 12:578-580, 595-599.
