"What branch of mathematics was founded from a paper ""On a Characteristic Property of All Real Algebraic Numbers"" (1874) by Georg Cantor, who built on the work of Zeno, Bernard Bolzano & Richard Dedekind, which, in turn was followed up by Bertrand Russell, Ernst Zermelo, Abraham Fraenkel & Henri Lebesgue?"
Abraham Fraenkel to improve Zermelo's axiomatic system; the result is the Zermelo–Fraenkel axioms. Fraenkel worked in set theory and foundational mathematics. Fraenkel also was interested in the history of mathematics, writing in 1920 and 1930 about Gauss's works in algebra, and he published a biography of Georg Cantor. After retiring from the Hebrew University and being succeeded by his former student Abraham Robinson, Fraenkel continued teaching at the Bar Ilan University in Ramat Gan (near Tel Aviv). Abraham Fraenkel Abraham Halevi (Adolf) Fraenkel (; February 17, 1891 – October 15, 1965), known as Abraham Fraenkel, was a German mathematician. He was an
Set theory founded by a single paper in 1874 by Georg Cantor: "On a Property of the Collection of All Real Algebraic Numbers". Since the 5th century BC, beginning with Greek mathematician Zeno of Elea in the West and early Indian mathematicians in the East, mathematicians had struggled with the concept of infinity. Especially notable is the work of Bernard Bolzano in the first half of the 19th century. Modern understanding of infinity began in 1870–1874 and was motivated by Cantor's work in real analysis. An 1872 meeting between Cantor and Richard Dedekind influenced Cantor's thinking and culminated in Cantor's 1874 paper.
