It was created at the end of the 19th century by Georg Cantor as part of his study of infinite sets.

Some believe that Georg Cantor's set theory was not actually implicated by these paradoxes ( see Frápolli 1991 ); one difficulty in determining this with certainty is that Cantor did not provide an axiomatization of his system.

Cantor was able to support a family despite modest academic pay, thanks to his inheritance from his father.

Cantor was promoted to Extraordinary Professor in 1872 and made full Professor in 1879.

To attain the latter rank at the age of 34 was a notable accomplishment, but Cantor desired a chair at a more prestigious university, in particular at Berlin, at that time the leading German university.
