George Green
George Green was a British mathematical physicist born in Sneinton, Nottinghamshire, now part of the city of Nottingham.
Despite receiving little recognition during his lifetime, he is best remembered for his Essay on electricity and magnetism published in 1828. In this essay he introduced an early version of Green's theorem in vector calculus, the notion of potential functions as currently used in physics, and a method of solving differential equations called Green's functions. This paper formed the foundation for the work of later scientists such as William Thomson, among many others. His work on potentials ran parallel to that of Carl Friedrich Gauss.
