KONSTANDINOS KARATHEODORY

KONSTANDINOS KARATHEODORY or Constantin Carathéodory (1873-1950 ) was a Greek mathematician. He made significant contributions to the theory of functions of a real variable, the calculus of variations, and measure theory. His work also includes important results in conformal representations and in the theory of boundary correspondence. In 1909, Carathéodory pioneered the Axiomatic Formulation of Thermodynamics along a purely geometrical approach. As a student he was considered as Charismatic and brilliant.
Constantin Carathéodory was born in Berlin from Greek parents and grew up in Brussels. His family members held many important governmental positions.

Constantin began his formal schooling at a private school in Vanderstock in 1881. In 1885 he attended a grammar school for a year where he first began to become interested in mathematics. In 1886 he entered the high school Athénée Royal d'Ixelles and studied there until his graduation in 1891. Twice during his time at this school Constantin won a prize as the best mathematics student in Belgium.

He trained  as a military engineer and when war broke out between Greece and Turkey he went to Egypt to work for the construction of the Assuit dam. During periods when construction work had to stop due to floods, he studied mathematics from some textbooks he had with him. He also visited the Cheops Pyramid and made measurements which he wrote up and published in 1901. He also published a book on Egypt in the same year which contained a wealth of information on the history and geography of the country.
He taught at many Universities, Bonn, Hannover, Breslau, Gottingen, Berlin, Prussian Academy, Ionian University of Smyrni, Athens, Munich. He had many brilliant students, among them Radenmacher, Paul Finsler, Hilbert, Einstein e.t.c.
He spoke English, Italian, Turkish, Ancient Languages, French and German.
