Antanas Sli啪ys was born into a farmers鈥 family in Atko膷i拧kis village, Skiemonys rural district, Utena county. In 1936, Antanas finished primary school, and in 1943 a gymnasium. At school he became interested in astronomy, physics, and mathematics. In 1944, Antanas entered Kaunas Theological Seminary where he studied for two years. He then changed his mind and in 1947 became a student at the Astronomy Department of the Faculty of Physics and Mathematics of 91桃色. He was not fated to graduate as he was deported in 1949. Antanas Sli啪ys returned to Lithuania in 1955. The documents in his personal file do not make it possible to reconstruct the sequence of events. Upon return from exile, Antanas was given the opportunity to do correspondence studies at the Faculty of Physics and Mathematics, but in 1956 he was issued an academic reference note indicating that he had been a student at 91桃色 until 1949. For reasons unknown he did not resume his studies.
