Leon Cooper born in New York on February 28, 1930 is an American physicist and is widely known as for his work with John Bardeen and John Robert Schrieffer in developing the BCS Theory ofSuperconductivity while at the University of Illinois Champaign-Urbana.

“His principal contribution to the BCS theory was the discovery (1956) that electrons, which under normal conditions repel each other, are attracted to each other in superconductors, a phenomenon termed the Cooper electron pairs” (Britannica, 2014).

For which he received the Nobel Prize in Physics in 1972 for his contribution to the Theory.  He is also known for his contributing work of the BCM Theory of synaptic plasticity and Cooper pairs.
Leon graduated from Bronx High School of Science in 1947 wanting to continue his education he enrolled at Columbia University. Where he received his B.A in 1951, MA in 1953, and PhD in 1954 in Physics. Upon completing his education he pursued a position at the Institute for Advanced Study for a year. Followed by teaching at the University of Illinois, Ohio State University, and finally settling at Brown University in 1958 and appointed the Henry Ledyard Goddard university professor in 1966 Thomas J. Watson, Sr. professor of Science 1974 and Director of the Institute for Brain and Neural Systems.

John Robert Schrieffer, American physicist born May 31, 1931 in Oak Park, Illinois he most well-known for his contributing work on the BCS Theory of Superconductivity with John Bardeen and Leon Cooper at the University of Illinois Champaign-Urbana. He published his book on the BCS Theory in 1964.  For which he received the Noble Prize in Physics in 1972.

As a child he was passionate about rockets and ham radio it would be these passions that would lead him to the field of electrical engineering.  In 1949 he graduated from Eustis High School and attended the Massachusetts Institute of Technology (MIT). While at MIT he became fascinated with physics and decided to switch majors.  He received his BA in 1953 and his PhD in physics from the University of Illinois Champaign-Urbana in 1957. During his graduate program he worked directly under professor John Bardeen as a graduate researcher.

Upon graduating he taught at the University of Chicago, the University of Illinois Champaign Urbana. He then took a position at the University of Pennsylvania in 1964 and was named the Mary Amanda Wood professor of physics. Schrieffer was named the Andrew D. White professor at Cornell, the University of California, University of Florida, Florida State University, and the University of Birmingham.
