## Richard Dedekind (1831-1916)

German mathematician who proposed an axiomatic definition of the set of integers as well as an explicit construction of real numbers based on rational numbers. Dedekind introduced the notation $$\mathbb{N}$$ in 1888 to refer to the set of non-zero natural numbers. Today, this set is denoted by $$\mathbb{N}$$*. Dedekind also proposed the use of the symbol $$\mathbb{R}$$ to refer to the set of real numbers and the use of the symbol $$\mathbb{Z}$$ to refer to the set of integers.
