Childhood & Early Life

From 1895 to 1907, he studied at the K¨ollnisches Gymnasium. He demonstrated a keen interest in music and became an immensely talented pianist. He later explored his talent in composing music as well.

Childhood & Early Life

He also studied at the Technische Hochschule Charlottenburg for about half a year. During his school life, he also enjoyed studying ancient languages and mathematics.

Childhood & Early Life

After school, he joined the University of Berlin where he studied for four semesters primarily under Issai Schtur, Landau, Frobenius, and Schottky in mathematics; Riehl, Stumpf, and Cassirer in philosophy, and Max Planck in physics.

Childhood & Early Life

Subsequently, he studied at Gottingen for six semesters, majoring in mathematics and studying philosophy and theoretical physics as additional subjects. He attended lectures on mathematics mainly by Hilbert, Landau, Weyl and Klein; on physics by Voigt and Born, and on philosophy chiefly by Leonard Nelson.

Childhood & Early Life

In 1912, Paul Bernays received his Ph.D. in mathematics from the University of Berlin. His doctoral dissertation on the analytic number theory of binary quadratic forms was completed under Landau.

Career

Later that year, he obtained his Habilitation from the University of Zurich for a dissertation on complex analysis and Picard's theorem, completed under professor Zermelo.

Career

He was a Privatdozent at the University of Z¨urich from 1912 to 1917. During this period, he became acquainted with Georg P´olya, Einstein, and Hermann Weyl.

Career

In 1917, he was invited by Hilbert to assist him in his research of the foundations of arithmetic. The job took him back to Gottingen and he helped Hilbert in preparing lectures and notes.

Alongside, he also gave lectures on mathematics at the University of Gottingen, where he obtained the Venia Legendi in 1919.

Career

Paul Bernays' partnership with Hilbert resulted in a two volume work, ‘Grundlagen der Mathematik’ (1934–1939). The work attempted to build mathematics from symbolic logic and a proof from it is now known as the Hilbert–Bernays paradox.

Major Works

In seven papers published in the Journal of Symbolic Logic between 1937 and 1954, he embarked on the axiomatic set theory whose foundation was laid by John von Neumann in the 1920s. Bernays’ theory, with some alterations by Kurt Gödel later, came to be known as the Von Neumann–Bernays–Gödel set theory.

In 1956, he revised Hilbert’s ‘Grundlagen der Geometrie’ (1899) on the foundations of geometry. He believed that the whole structure of mathematics could be combined as a single logical entity.

Major Works

Bernays research in proof theory and axiomatic set theory helped to produce a new discipline of mathematical logic. His axiomatic set theory was further developed by Kurt Gödel and is presently known as the Von Neumann–Bernays–Gödel set theory.
