GEORG CANTOR (1845–1918)
GEORG CANTOR (1845–1918) Georg Cantor was born in St. Petersburg, Russia, where his father was a
successful merchant. Cantor developed his interest in mathematics in his teens. He began his university studies
in Zurich in 1862, but when his father died he left Zurich. He continued his university studies at the University
of Berlin in 1863, where he studied under the eminent mathematicians Weierstrass, Kummer, and Kronecker.
He received his doctor’s degree in 1867, after having written a dissertation on number theory. Cantor assumed
a position at the University of Halle in 1869, where he continued working until his death.
Cantor is considered the founder of set theory. His contributions in this area include the discovery that the
set of real numbers is uncountable. He is also noted for his many important contributions to analysis. Cantor
also was interested in philosophy and wrote papers relating his theory of sets with metaphysics.
Cantor married in 1874 and had five children. His melancholy temperament was balanced by his wife’s happy disposition.
Although he received a large inheritance from his father, he was poorly paid as a professor. To mitigate this, he tried to obtain a
better-paying position at the University of Berlin. His appointment there was blocked by Kronecker, who did not agree with Cantor’s
views on set theory. Cantor suffered from mental illness throughout the later years of his life. He died in 1918 from a heart attack.
