Solomon Lefschetz Solomon Lefschetz (1884-1972) did pioneering work in algebraic geometry, algebraic topology, and differential equations, and exerted tremendous influence over American mathematics as a professor at Princeton University and the editor of the journal Annals of Mathematics Lefschetz was born in Moscow into a Jewish family. His father had frequent business in Persia, and usually based his family in Paris. At age 21 Lefschetz emigrated to the United States. He worked briefly at the Baldwin Locomotive Works, then for Westinghouse Electric Company in Pittsburg from 1907 to 1910. His industrial career was cut short by an accident in which he lost both his hands. Lefschetz started over as a mathematician, receiving his doctorate from Clark University in 1911. Lefschetz accepted a position at the University of Nebraska, then moved to the University of Kansas. Despite heavy teaching demands and near-complete isolation from other research mathematicians, he produced research papers of striking originality and importance. (He later wrote that his position "enabled me to develop my ideas in perfect mathematical calm".) In 1924 he went to Princeton as a visiting professor, and his post was made permanent the next year. Lefschetz became Henry Fine research professor in 1932 and retained that post until his retirement from Princeton in 1953. Lefschetz began his research by studying algebraic varieties (sets defined by the vanishing of polynomials). He applied to them the ideas of algebraic topology invented by

The following article about Solomon Lefschetz by Kristina Nilson Allen appeared in Clark News , volume 11, number 1, January 1988, page 9. Undaunted Genius The launching of Sputnik in 1957 galvanized the United States and brought one of America's greatest mathematicians, Solomon Lefschetz, out of retirement to pick up the gauntlet hurled from outer space. Lefschetz, who had received his doctorate from Clark in 1911, had been studying closely the research of Russian scientists. He was certain that the Soviets' superior knowledge of nonlinear differential equations (which deal with the laws of natural motion) had given them the edge in rocket control systems. Lefschetz convinced the Martin Company, an aircraft manufacturer, to set up a mathematics research center as part of their independent Research Institute for Advanced Study in Baltimore. In a year, Lefschetz was directing the research of 17 scientists focused on nonlinear differential equations. It was the largest group of mathematicians in the Western world to tackle such a project. This project culminated a career which had brought Lefschetz worldwide recognition for outstanding contributions to the fields of algebraic geometry, topology (the geometry of form without size or shape) and nonlinear differential equations. Ironically, Lefschetz turned to mathematics only after an accident curtailed a career in engineering. Born in Moscow in 1884 and raised in Paris, Lefschetz had earned his degree in 1905 in mechanical engineering at the Ecole Centrale. In 1907 he began work as an engineer with Westinghouse Electrical and Manufacturing Company in Pittsburgh, but at age 23, Lefschetz lost both hands and forearms in an electrical experiment accident.

Mathematics Mathematics has been prominent in the Princeton curriculum since the founding of the College. In 1760, entering students were required to have an understanding of the rules of arithmetic, and underclassmen learned algebra, trigonometry, geometry, and conic sections. In 1853 a Boston newspaper reported that at Princeton the study of mathematics was carried on ``to an extent not excelled by any other college in the country.'' In the early years, instruction in mathematics was given by faculty members who generally taught other subjects as well. The first trained mathematician on the faculty was Walter Minto, who had studied in Pisa and had taught in Edinburgh before being called to Princeton in 1787. Not until a century later did the College again have on its faculty teachers who had studied in the European mathematical centers; the first was Henry Burchard Fine (A.B. Princeton 1880), who received his Ph.D. degree at Leipzig in 1885. Under the chairmanship, from 1929 to 1945, of Fine's successor, Luther P. Eisenhart, the department continued to make outstanding appointments of promising young mathematicians, such as Alonzo Church, a noted logician; Eugene P. Wigner, Thomas D. Jones Professor of Mathematical Physics and later a Nobel laureate; Salomon Bochner, known for the breadth of his contributions to many different areas of analysis; and Samuel S. Wilks, a distinguished mathematical statistician. With the permanent mathematical faculties and visiting members of the University and the Institute, Princeton became an intensely active center for mathematical research in the 1930s. Reporting on an International Congress of Mathematicians held in Oslo in 1936, a Norwegian newspaper ran this headline: ``Princeton is the mathematical center of the world but at the moment it is in Oslo.''
