Bell’s Theorem

While on leave from the European Organization for Nuclear Research he went to spend time at Stanford University. John Stewart Bell also went to University of Wisconsin–Madison and later to Brandeis University. The following year after his leave, he jotted a paper titled "On the Einstein-Podolsky-Rosen Paradox." This work described how one could derive his most notable theorem that would be called Bell’s Theorem. However, his work was faced by numerous debates with regards to the (Einstein–Podolsky–Rosen) EPR analysis. 

Personal Life

While John Stewart Bell was in the United Kingdom working on a particle accelerator, he met Mary Ross whom would later be his wife. He married Ross in 1954.
