Biography Georgi Bradistilov, the fourth and youngest child in the family of the high-ranked civil servant at Bulgarian Ministry of Finance, Delcho Petkov Bradistilov (1866 – 1927), and teacher Nona Georgieva Bradistilova (née Motekova) (1876 – 1958), was born on 12 October 1904 OS in Panagyurishte. He attended 3rd Sofia gymnasium and in 1922 entered Sofia University to study physics and mathematics. In 1927, he graduated with honors and the same year was appointed as assistant professor in mathematics. In the 1930s he studied at the University of Paris and the Ludwig-Maximilians-Universität München. Bradistilov was one of the last students to take Arnold Sommerfeld's course in theoretical physics before his retirement. In 1938, he defended his doctorate, with Oskar Perron as advisor, at the Ludwig-Maximilians-Universität München. Upon his return to Bulgaria Dr Bradistilov taught as private docent at his alma mater Sofia University. In 1943, he joined as extraordinary professor and later as full professor the newly established Higher Technical School in Sofia, which after the Second World War was renamed the State Polytechnic. Apart from his teaching duties, he wrote the basic mathematics textbooks used for many years by future Bulgarian engineers. He was rector of the State Polytechnic…
