 Sachs wanted to explore with him the features of nonlocality and nonlinearity that are absent in the quantum theory, but must be present in a field theory.Unfortunately Einstein died in April 1955 and Sachs never had the opportunity to talk to him about his ideas.In 1956 Sachs became a Senior Scientist at Lockheed Missiles and Space Laboratory, Based in Sunnyvale and adjacent to the NASA-Marshall Space Flight Center, Moffett Field, Lockheed Martin Missiles and Space Systems was and continues to be one of the most important satellite development and manufacturing plants in the United States, covering 412 acres.
