Sima Mejerovičiūtė (1913–?) was born in Vilnius. She graduated from an elementary school and four gymnasium forms. Later on, she entered the private Vilnius teachers’ seminary Tarbut. In 1937, due to an illness, she postponed part of the final examinations and received a seminary certificate on 1 July 1938. Due to her poor financial situation, she worked for several years after studies and entered the Department of Biology of the Faculty of Mathematics and Nature of Vilnius University only in September 1940. She studied there for a year. On 19 September 1941 she 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. According to Yad Vashem Holocaust victim database, it can be assumed that she was killed during the Holocaust.
