On the morning of 4th July 1941, in German captured city Lvov, a number of Polish University professors were executed with their families. Lvov was a Polish city since XIV Century, and has a very good University. After German, and then Soviet invasion on Poland in 1939 Lvov was included in Soviet occupation zone. Both invaders started elimination of Polish elite. Symbol of Soviet atrocities is the Katyn Massacre. Germans organized their own AB-Action. In 1939-1940 both invaders coordinated elimination of Polish leaders.
“In direct continuation of the AB Action was a German campaign in the east started after the German invasion of the USSR. Among the most notable mass executions of Polish professors was the massacre of Lwów professors, in which approximately 45 professors of the university in Lwów were murdered together with their families and guests. Among those killed in the massacre were Tadeusz Boy-Żeleński, former Polish prime minister Kazimierz Bartel, Włodzimierz Stożek, and Stanisław Ruziewicz. Thousands more perished in the Ponary massacre by Lithuanians in German Service, in German concentration camps, and in ghettos.”
