Moor-Jankowski was born in
Warsaw and grew up in
Częstochowa. His father was an
engineer and an
architect, and his mother a
concert pianist. When his mother's cousin developed
cancer, at the age of five, Moor-Jankowski decided that he wanted to be a
research physician in order to find a cure. When
Germany invaded Poland in 1939, Moor-Jankowski joined the Polish Army, at the age of 15, and his family moved back to Warsaw. When Poland was overrun, the family moved back to Częstochowa. With the Polish schools closed by the
Nazis, he obtained a
high school diploma without official government recognition. When his father disappeared in 1942, Moor-Jankowski joined the
Polish Resistance. He would later write that he wanted something of himself to carry on, and so he fathered a son, Tadeusz, who was born in 1942. He saw the child once, when he was two weeks old, but did not see him again for 35 years. Moor-Jankowski was fighting in
Warsaw uprising. He was injured by an explosive bullet in his knee, and he was forced to move from hospital to hospital, pretending to be a German officer in order to survive. Eventually, his impersonation was discovered, and he was imprisoned by the Germans, and then later by the
Soviets. He finally escaped to
Switzerland, where he earned a medical degree. ==Career==
