Julius Wilhelm Richard Dedekind (1831 - 1916) redefined the notion of irrational numbers

in terms of Dedekind cuts, and thus gave a construction of the real numbers. He was a good

friend of Cantor, and encouraged him to publish, even though the results seemed counter-intuitive.

He also introduced the notion of an ideal which is fundamental to ring theory.
