Doctors' plot
Stern was born in a Jewish family in a small Ukrainian town of Zhmerynka. In 1944 he received his doctor degree, and in 1947 organized in Chernovtsy the first endocrinological center in Ukraine. In 1952 he moved to Vinnitsa. The same year he was discharged because of the Doctors' plot, an imaginary conspiracy of Jewish doctors to poison Soviet leaders. He was reinstated in 1954, a year after Stalin's death. In 1963, Stern became a section head in a newly established endocrinological center in Vinnitsa.
