Mathematician:Arthur Cayley

From ProofWiki
Jump to: navigation, search


English mathematician most famous for his work in group theory and graph theory.

The first to study groups as an abstract concept in their own right.

Also one of the pioneers of matrix algebra, and hence sometimes cited as one of the "fathers" of matrix theory.




  • Born: 16 August 1821 in Richmond, Surrey, England
  • Died: 26 January 1895 in Cambridge, Cambridgeshire, England

Notable Quotes

It is difficult to give an idea of the vast scope of modern mathematics. The word "scope" is not the best; I have in mind an expanse swarming with beautiful details, not the uniform expanse of a bare plain, but a region of a beautiful country, first seen at a distance, but worthy of being surveyed from one end to the other and studied even in its smallest details: its valleys, streams, rocks, woods and flowers.
