45. Eugene Lukacs, 1906-1987 mathematics at University of Vienna. He took courses with Hans Hahn, EduardHelly, Walter Meyer, Leopold Vietoris and wilhelm wirtinger. http://www.bgsu.edu/departments/math/faculty/Lukacs.html

EUGENE LUKACS Eugene Lukacs was born in Szombathely, Hungary on August 14, 1906. Six weeks after his birth, he was brought to Vienna where he grew up, got his primary and secondary education and studied mathematics at University of Vienna. He took courses with Hans Hahn, Eduard Helly, Walter Meyer, Leopold Vietoris and Wilhelm Wirtinger. Eugene met his wife to be, Elizabeth Weisz, at the University of Vienna in 1927. She was taking Mathematics and Physics. They were married in 1935. Eugene's interest in geometry led him to write a Ph.D. dissertation under Walter Meyer. He earned his Ph.D. degree in 1930. Subsequently he took an actuarial degree in 1931. Due to scarceness of positions at the University, Eugene taught secondary school in Vienna for two years. Then he accepted a position as an actuary at an insurance company. E. Helly and Z.W. Birnbaum were amongst his colleagues. He stayed with the company until 1937 and also taught extension courses in mathematics at the Volkshochschule Wien Volksheim. When Germany annexed Austria in 1938 he decided to emigrate to USA arriving here in February 1939. About the same time many other Jewish statisticians and mathematicians emigrated to the United States. These included Gerhard Tintner, Z.W. Birnbaum, Henry Mann, Oscar Morgenstern and Abraham Wald. Upon arrival, Eugene renewed his acquaintance with Abraham Wald whom he had met in Vienna. Under Wald's influence Eugene became interested in probability and statistics. Wald introduced him to the vast literature on probability and statistics that was largely unknown in Central Europe at that time. Wald invited him to attend his, and Hotelling's lectures at Columbia. Thus began Eugene's long and fruitful career in statistics during which he wrote five books and well over 100 papers.

Erwin Rudolf Josef Alexander Schrödinger Born: 12 Aug 1887 in Erdberg, Vienna, Austria Died: 4 Jan 1961 in Vienna, Austria Erwin Schrödinger 's father Rudolf Schrödinger ran a small linoleum factory which he had inherited from his own father. Erwin's mother, Emily Bauer, was half English, this side of the family coning from Leamington Spa, and half Austrian with her father coming from Vienna. Schrödinger learnt English and German almost at the same time due to the fact that both were spoken in the household. He was not sent to elementary school, but received lessons at home from a private tutor up to the age of ten. He entered the Akademisches Gymnasium in the autumn of 1898, rather later than was usual since he spent a long holiday in England around the time he might have entered the school. He wrote later about his time at the Gymnasium:- I was a good student in all subjects, loved mathematics and physics, but also the strict logic of the ancient grammars, hated only memorising incidental dates and facts. Of the German poets, I loved especially the dramatists, but hated the pedantic dissection of this works. In [15] there is the following quotation from a student in Schrödinger's class at school:- Especially in physics and mathematics, Schrödinger had a gift for understanding that allowed him, without any homework, immediately and directly to comprehend all the material during the class hours and to apply it. After the lecture ... it was possible for [our professor] to call Schrödinger immediately to the blackboard and to set him problems, which he solved with playful facility.

After this he undertook voluntary military service in the fortress artillery. Then he was appointed to an assistantship at Vienna but, rather surprisingly, in experimental physics rather than theoretical physics. He later said that his experiences conducting experiments proved an invaluable asset to his theoretical work since it gave him a practical philosophical framework in which to set his theoretical ideas.

51. Otto Biermann Vzhledem k Biermannovu špatnému zdravotnímu stavu byl nakonec odmítnuta jmenován byl wilhelm wirtinger. Již v polovine 90. http://www.math.muni.cz/math/biografie/otto_biermann.html

August Leo Otto Biermann Narozen: 5. listopadu 1858 v Tì¹ínì Zemøel: 28. dubna 1909 v Brnì Otto Biermann byl synem historika Gottlieba Biermanna (1824-1901) pozdìj¹ího øeditele pra¾ského nìmeckého gymnázia na Malé Stranì. V rodném Tì¹ínì zaèal studovat na gymnáziu a ve studiu pak pokraèoval na gymnáziu na Malé Stranì v Praze. Na této ¹kole v roce 1876 maturoval a na podzim se zapsal na filozofickou fakultu pra¾ské univerzity, kde studoval do konce ¹kolního roku 1877/78. V následujících dvou letech se vìnoval studiu matematiky, fyziky a astronomie na univerzitì ve Vídni. V roce 1880 vykonal ve Vídni zkou¹ku uèitelské zpùsobilosti, která ho opravòovala k výuce matematiky a fyziky na gymnáziích. V tém¾e roce získal ve Vídni 19. èervna doktorát filozofie za disertaèní práci Über die Reihenentwicklung der Lösungen der Modular- und Multiplikator-Gleichungen und die Diskriminanten V období od 1. øíjna 1880 do 30. záøí 1881 vykonával Biermann jednoroèní dobrovolnou vojenskou slu¾bu, po jejím¾ skonèení pokraèoval s podporou státního stipendia ve studiu na berlínské univerzitì, kde nav¹tìvoval ve ¹kolním roce 1881/82 pøedev¹ím pøedná¹ky profesora Karla Weierstrasse (1815-1897). Berlínský pobyt sehrál v období Biermannova vìdeckého zrání významnou roli. Brzy po návratu do Prahy pøedlo¾il v øíjnu 1882 na univerzitì v Praze habilitaèní práci Über die Reduction hyperelliptischer Integrale auf elliptische . 24. února 1883 byl po úspì¹ném habilitaèním øízení jmenován soukromým docentem.

Na podzim roku 1874 se stal asistentem matematiky u profesora Wincklera na technice a na tomto místì setrval a¾ do roku 1879. V roce 1875 vykonal Hoèevar zkou¹ku uèitelské zpùsobilosti pro matematiku a fyziku a v následujícím roce získal na univerzitì ve Vídni doktorát za práci Über einige bestimmte Integrale . Ve ¹kolním roce 1875/76 Hoèevar absolvoval pøedepsaný zku¹ební rok na gymnáziu pøi Tereziánské akademii ve Vídni. V roce 1879 byl jmenován uèitelem na státním vy¹¹ím gymnáziu v Innsbrucku, kde v roce 1882 získal definitivu. V roce 1883 se Hoèevar habilitoval pro infinitezimální poèet a jeho u¾ití v geometrii na univerzitì v Innsbrucku. Jako soukromý docent konal na univerzitì pøedná¹ky a¾ do roku 1891. V roce 1885 se Hoèevar neúspì¹nì ucházel o místo profesora matematiky na technice v Brnì. Úspì¹ný byl a¾ v roce 1891, kdy ho císaø jmenoval 17. srpna mimoøádným profesorem spoleènì s

60. History Of Operator Theory (The word spectrum seems to have been adopted by Hilbert from an 1897 articleby wilhelm wirtinger.) Hilbert began like Fredholm, with the specific idea of http://www.mathphysics.com/opthy/OpHistory.html

A Short History of Operator Theory by Evans M. Harrell II In the first textbook on operator theory, published in Warsaw 1932, Stefan Banach states that the subject of the book is the study of functions on spaces of infinite dimension, especially those he coyly refers to as spaces of type B, otherwise Banach spaces definition This was a good description for Banach, but tastes vary. I propose rather the "operational" definition that operators act like matrices . And what that means depends on who you are. If you are an engineering student, matrices are particular symbols you manipulate to solve linear systems. As a working engineer you may instead use Heaviside's operational calculus, in which you are permitted to do all sorts of dangerous manipulations of symbols for derivatives and what not, exactly as if they were matrices, in order to solve linear problems of applied analysis. About 90% of the time you will get the right answer, just like the student; somewhat more with experience. And that is good enough, if the bridges you build aren't where I drive. In mathematics the student of elementary analysis learns that matrices are linear functions relating finite-dimensional vector spaces, and conversely. As a working mathematician the analyst has lost all fear of minor matters like infinity, and will happy agree with Banach's definition.
