Background
Loewner was born on May 29, 1893, in Lány, Czech Republic, into a Jewish family. His father, Sigmund Loewner, was a store owner, his mother's name was Jana Loewner.

Loewner studied mathematics with G. Pick at the Charles University in Prague and received the Ph.D. in 1917.
(Professor of Mathematics at Stanford University from 1950...)
Professor of Mathematics at Stanford University from 1950 until his death in 1968, Charles Loewner occasionally taught as a Visiting Professor at the University of California at Berkeley. After his 1955 course at Berkeley on continuous groups, Loewner's lectures were reproduced in the form of mimeographed notes. The professor had intended to develop these notes into a book, but the project was still in formative stages at the time of his death. The 1971 edition compiles edited and updated versions of Professor Loewner's original fourteen lectures, making them available in permanent form.

Loewner was born on May 29, 1893, in Lány, Czech Republic, into a Jewish family. His father, Sigmund Loewner, was a store owner, his mother's name was Jana Loewner.
Loewner studied mathematics with G. Pick at the Charles University in Prague and received the Ph.D. in 1917.
From 1917 to 1922 Loewner was an assistant at the German Technical University of Prague; from 1922 to 1928, assistant and Privatdozent at the University of Berlin; from 1928 to 1930, extraordinary professor at the University of Cologne; and from 1930 to 1939, full professor at Charles University in Prague, which he left when the Nazis occupied Czechoslovakia. From 1939 to 1944 he was lecturer and assistant professor at the University of Louisville, Kentucky; from 1945 to 1946, associate professor, and from 1946 to 1951, full professor at Syracuse University; and from 1951 until his retirement in 1963, full professor at Stanford University.
Loewner had a large number of research students, even after his retirement. His knowledge of mathematics was broad and profound, and included significant parts of mathematical physics. His originality was remarkable; he chose as his problems far from fashionable topics.
Among Loewner’s other papers, many of which deal with physics, one should be mentioned explicitly: his non-Archimedean measure in Hilbert space, which despite its startling originality (or rather because of it) has drawn little attention outside the circle of those who know Loewner’s work.

1971One idea pervades Loewner’s work from his Ph.D. thesis: applying Lie theory concepts and methods to semigroups, and applying semigroups to unexpected mathematical situations. This led him in 1923 to a sensational result: the first significant contribution to the Bieberbach hypothesis.Loewner studied minimal semigroup extensions of Lie groups; for the group of the real projective line there are two: that of monotonic mappings of infinite order, and its inverse. He also studied semigroups in a more geometrical context; deformation theorems for projective and Moebius translations, and infinitesimally generated semigroups invariant under the non-Euclidean or Moebius group, particularly if finite dimensionality and minimality are requested.
Of short stature, soft-spoken, modest, shy (but exceedingly kind to his acquaintances), Loewner had a large number of research students, even after his retirement. His originality was remarkable; he chose as his problems far from fashionable topics.
Loewner was married to Elizabeth Alexander, who died in 1955; they had one daughter.
