mathematics.

Schmidt’s most significant contributions to mathematics were in integral equations and in the founding of Hilbert space theory. Specifically, he simplified and extended David Hilbert’s results in the theory of integral equations; and he formalized Hilbert’s distinct ideas on integral equations into the single concept of a Hilbert space, in the process introducing many geometrical terms. In addition he made contributions in the fields of partial differential equations and geometry. The most important of these discoveries were the extensions of the isoperimetric inequality, first to n-dimensional Euclidean space and then to multidimensional hyperbolic and spherical spaces. Although his methods were classical rather than abstractionist, nevertheless he must be considered a founder of modern functional analysis.

Erhard Schmidt

Baltic German mathematician

For the World War I Imperial German Admiral, see Erhard Schmidt (admiral).

Erhard Schmidt (13 January 1876 – 6 December 1959) was a Baltic German mathematician whose work significantly influenced the direction of mathematics in the twentieth century.^[2] Schmidt was born in Tartu (German: Dorpat), in the Governorate of Livonia (now Estonia).

Mathematics

His advisor was David Hilbert^[1] and he was awarded his doctorate from University of Göttingen in 1905. His doctoral dissertation was entitled Entwickelung willkürlicher Funktionen nach Systemen vorgeschriebener and was a work on integral equations.^[1] Together with David Hilbert he made important contributions to functional analysis. Ernst Zermelo credited conversations with Schmidt for the idea and method for his classic 1904 proof of the Well-ordering theorem from an "Axiom of choice", which has become an integral part of modern set theory.^[3]

After the war, in 1948, Schmidt founded and became the first editor-in-chief of t

Ehrhard Schmidt

German navy admiral

For the Kaiserliche Marine ship, see SMS Viceadmiral E. Schmidt.

Ehrhard Schmidt (18 May 1863 – 18 July 1946) was an admiral of the Kaiserliche Marine (Imperial German Navy) during World War I.

Career

At age 15, he entered the navy and saw service at several branches at sea and on land. Among them were posts on missions, as a commanding officer and in cadet training. His wish to become commander of a ship was granted in 1901 when he assumed command of the armoured cruiserPrinz Adalbert. He held that command until 1907. From 1908 to 1910, he commanded the Braunschweig-class battleship Hessen and was afterwards promoted to Konteradmiral to command the II Squadron of the Offshore Fleet. Later he was commander of the naval artillery.

At the beginning of World War I, he was commander of the IV Squadron, made up of old Wittelsbach-class ships. During the Battle of Jutland, Schmidt commanded the I Squadron and used it as a vanguard to break through the British lines at night. In 1917, he led Operation Albion, a special
