George Green (14 July 1793 – 31 May 1841) was a British mathematical physicist who writes An Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism (Green, 1828).

The essay introduces several important concepts, among them a theorem similar to the modern Green's theorem, the idea of potential functions as currently used in physics, and the concept of what are now called Green's functions.

Green is the first person to create a mathematical theory of electricity and magnetism and his theory forms the foundation for the work of other scientists such as James Clerk Maxwell, William Thomson, and others.

His work on potential theory ran parallel to that of Carl Friedrich Gauss.

Green's life story is remarkable in that he is almost entirely self-taught.

He received only about one year of formal schooling as a child, between the ages of 8 and 9.
