German-American engineer Bernhard Caesar Einstein was better known as the son of Hans Albert Einstein and the grandson of legendary physicists Albert Einstein and Mileva Marić. It is believed Bernhard was quite close to his grandfather in childhood. Initially raised in Switzerland, he later moved with his family to the US, as his father was pushed by his grandfather to escape the rising Nazis in Europe. He later joined the US Army and was stationed in Germany. The only one of the four biological children of his parents to reach adulthood, Bernhard was educated at UC Berkeley and ETH Zurich. Bernhard later worked as an engineer with organizations such as Texas Instruments in Dallas, Texas; ITT in Los Angeles, California; and Litton Industries in the San Francisco Bay Area. Throughout his career, he achieved multiple patents in electronics and specialized in electron tube technology, laser technology, and night vision light amplification.
