My father was in the infantry, WWII. He had signed up for the Army Specialized Training Program, which sent thousands of soldiers and high school graduates to college with the goal of preparing them for service as engineers, administrators, and whatnot. The program ended after less than a year, and except for a few who were retained under other programs, all those bright young men got shipped off to basic and, mostly, the infantry. Dad was a scout; offered the opportunity to train as a sniper, he declined.
His father was in the Navy; a senior enlisted man before the war, he was made an officer when things got tight, and ultimately commanded a ship of some kind.
Mom was a teenager in Amsterdam when the Germans invaded, and most of her family was captured, killed, or dispersed (her father was a prominent communist, and was arrested early on and sent to Buchenwald; her mother was eventually captured and died in a camp – Ravensbruck, I think; of her brothers, one died fighting, one died in a camp, and one joined the merchant marine and went a bit mad, and died in an asylum sometime in the '60s). She took up with the resistance and served as a courier, smuggling messages, guns, food, etc., and somehow managed to keep a large dog alive and fed.
My father went to school in Switzerland after the war, where he met my mother – who was, I think, recuperating, but may have been taking business classes. They were married by her father in Amsterdam, and lived in Switzerland until 1950. My oldest brother was born there, in Lausanne.
