Life.
Towards the end of the First World War, his father, pharmacology researcher and physician, sent him to the Black Forest to a farmer so he could obtain food in exchange for manual labor.
In 1942, under the direction of Robert Oppenheimer, Peters completed his doctorate in physics. During his time at the Berkeley Radiation Laboratory Peters was active in the Federation of Architects, Engineers, Chemists and Technicians, a labor union affiliated to the Congress of Industrial Organizations.
In J Robert Oppenheimer's 1949 House Un-American Activities Committee hearing, Peters was accused of being a communist sympathizer, a "crazy person" and "quite a red" by Oppenheimer. The Rochester Times-Union broke the story a few days later, and Peters soon realized that his academic career in the US was affected. Peters could not find work in the United States. In 1951, he left the country to Mumbai, India, where he continued to study cosmic rays for eight years. Over the next four decades, he directed several studies on cosmic rays.
Peters died February 2, 1993 in Copenhagen, Denmark.
