Euclid was a greek mathematician who lived around 300 B.C. He is often considered the father of geometry - the inventor. He wrote the book 'Elements' which was the main source in teaching math and geometry as late as till a few hundred years ago. If you want to know more, I can recommend the Wikipedia article on Euclid, which is quite good :) en.wikipedia.org/wiki/Euclid.
