1. Richard Courant & Kurt Friedrichs Marker
Richard Courant and Kurt Friedrichs were co-founders of The Courant Institute of Mathematical Science a division of New York University that serves as a center for research and advanced training in computer science and mathematics. The Institute, named after Richard Courant, is considered to be one of the most prestigious and leading mathematics schools and mathematical sciences research centers in the world.
Richard Courant was born in Lublinitz in the German Empire's Prussian province of Silesia. He came to New York University in 1934 as a visiting professor after having left his position as director of the Mathematics Institute at the University of Gφttingen in Germany. In 1935, he was invited to build up NYU's Department of Mathematics at the Graduate School of Arts and Sciences. He was joined by Kurt Friedrichs and James Stoker, and together they formed a research group that became the Courant Institute.
Apart from his outstanding organizational talent, Courant is well remembered both for his mathematical achievements and for his conviction that pure mathematics had practical applications. He and David Hilbert authored the influential textbook Methods of Mathematical Physics, and he coauthored What is Mathematics? with Herbert Robbins.
Kurt Otto Friedrichs was born in Kiel, Germany. Before coming to this country in 1937, he taught at the Aerodynamics Institute in Aachen and the Institute of Technology in Braunschweig. Friedrichs' greatest contribution to applied mathematics was his work on partial differential equations, operators in Hilbert space, perturbation theory and bifurcation theory. In 1972, he was the recipient of the National Academy of Science Award in Applied Mathematics and in 1977 President Jimmy Carter presented him with the National Medal of Science.
Both Courant and Friedrichs were long-time New Rochelle residents and good friends. Courant lived at 142 Calton Road and Friedrichs at 24 Lester Place. Other Courant Institute faculty members who resided in New Rochelle included Fritz John, Harold Grad and Wilhelm Magnus.
