Jokūbas Smorgonskis (1923–?) was born in Vilnius. After completing seven forms of primary school (the name of which is unknown), he entered the electrotechnics class of Vilnius Jews’ Vocational School of Vilnius Society for the Advancement of Skilled Trades and Diligence (ORT) among Vilnius Jews. In July 1940, he graduated from the vocational school and applied to the Physics Department of the Faculty of Mathematics and Nature of Vilnius University.

On 19 September 1941, he was expelled from the university on the basis of the Order of 17 September 1941 of the Higher Education Department of the Board of Education, under the authority of the National Socialists.
