Karol Józef Wojtyła, known as John Paul II since his October 1978 election to the papacy, was born in the Polish town of Wadowice, a small city 50 kilometers from Krakow, on May 18, 1920. He was the youngest of three children born to Karol Wojtyła and Emilia Kaczorowska. His mother died in 1929. His eldest brother Edmund, a doctor, died in 1932 and his father, a non-commissioned army officer died in 1941. A sister, Olga, had died before he was born.

He was baptized on June 20, 1920 in the parish church of Wadowice by Fr. Franciszek Zak, made his First Holy Communion at age 9 and was confirmed at 18. Upon graduation from Marcin Wadowita high school in Wadowice, he enrolled in Krakow's Jagiellonian University in 1938 and in a school for drama.

The Nazi occupation forces closed the university in 1939 and young Karol had to work in a quarry (1940-1944) and then in the Solvay chemical factory to earn his living and to avoid being deported to Germany.

In 1942, aware of his call to the priesthood, he began courses in the clandestine seminary of Krakow, run by Cardinal Adam Stefan Sapieha, archbishop of Krakow. At the same time, Karol Wojtyła was one of the pioneers of the "Rhapsodic Theatre," also clandestine.
