James Clerk Maxwell (1831-1879) 

A Scotish physicist who wrote his first scientific paper at the age of 15.

After teaching in Aberdeen and London became first Cavendish professor of 

experimental physics at Cambridge, England.

His mathematical mind, working on the discoveries of Faraday and others, gave 

physics a celebrated set of equations for the basic laws of electricity and magnetism.

His work revolutionised the understanding of fundamental physics and was put 

to practical use by Hertz for his transmitting oscillator and later by Marconi 

for the invention of wireless telegraphy in December 1894.
