Born: 26 April 1933 | |||
Arno Allan Penzias was born in Munich, Germany on 26 April 1933, the eldest son of Karl and Justine Penzias. Because of the rise of Hitler and their Polish-Jewish decent, the elder Penzias sought ways of getting the family out of Germany. When the British government agreed to accept 10,000 Jewish children on humanitarian grounds, young Arno and his brother were put on the kindertransport. Their parents were able to join them several weeks later. Several months later the family headed for New York City, settling there in early 1940. | |||
As a child Penzias’ attended public schools in the Bronx, New York. As a teenager, he attended Brooklyn Technical High School, a specialized public school for boys and then matriculated at City College of New York planning to study chemical engineering.

An impressive accomplishment, but well behind most of his fellow physics majors. | |||

Penzias’ Army experience helped him obtain a research assistantship in the Columbia University Radiation Laboratory, which was then heavily involved in microwave physics.
