Kirill Borisovich Tolpygo

Kirill Borisovich Tolpygo (Russian: Кирилл Борисович Толпыго; Ukrainian: Кирилo Борисович Толпиго; 3 May 1916 – 13 May 1994), also known as K. B. Tolpygo, was a Soviet physicist and a corresponding member of the National Academy of Sciences of Ukraine. He was recognized for his works on condensed matter theory; the theory of phonon spectra in crystals; electronic structure and defects in insulators and semiconductors; and biophysics. He created the Department of Theoretical Physics and the Department of Biophysics at Donetsk National University. Tolpygo was a teacher, mentor and scientific adviser to graduate students. Tolpygo was awarded the Order of the Great Patriotic War (2nd Degree).

Tolpygo was born during WWI in Kyiv, Ukraine, then part of the Russian Empire. His father, Boris Nikolaevich Tolpygo (1889 – 1958) was a jurist who received the Order of St. Stanislaus for his services to the Russian army during World War I. Tolpygo's mother, Tatiana B. Bukreeva (1889 – 1992), was the daughter of Boris Yakovlevich Bukreev, a mathematician and geometer at Kyiv University (University of St. Volodymyr, Kyiv). In 1923, Tolpygo's father was arrested by the Cheka, for alleged "counter-revolutionary" activities. Through the intervention of individuals such as Raymond Poincaré, President of France, he avoided execution and was sentenced to 10 years hard labor. In 1947, Tolpygo's father was again imprisoned. It was 1957 before he would return to Kyiv, shortly before his death. Hence, Tolpygo grew up in the family of his grandfather, Boris Y. Bukreev.
