Joseph B. Keller

from Wikipedia, the free encyclopedia

Joseph Bishop Keller (born July 31, 1923 in Paterson , New Jersey , † September 7, 2016 in Palo Alto , California ) was an American mathematician who made important contributions to applied mathematics .


Keller studied mathematics at New York University and received his doctorate in 1948 under Richard Courant ( Reflection and Transmission of Electromagnetic Waves by Thin Curved Shells ). From 1948 to 1979 he was Professor of Mathematics at the Courant Institute of New York University and from 1979 to 1993 Professor of Mathematics and Mechanical Engineering at Stanford University . In 1993 he went into retirement.

His younger brother Herbert Keller , who did his doctorate with him, was also a well-known mathematician.


Keller has published more than 300 academic papers covering a wide range of applied mathematics. He is particularly famous for the geometric theory of diffraction he developed, inspired by work on sonar location during World War II, and for applications of the Einstein-Brillouin-Keller method (EBK) (named after him ) in the semiclassical approximation of the Quantum mechanics . He was a regular participant in the Geophysical Fluid Dynamics Program at the Woods Hole Oceanographic Institute.


Keller has received numerous awards for his achievements. In 1969 he was elected to the American Academy of Arts and Sciences . In 1976 and 1977 he received the Lester Randolph Ford Award from the Mathematical Association of America . In 1979 he was honored with the Theodore von Kármán Prize of the Society for Industrial and Applied Mathematics (SIAM). In 1981 he was awarded the A. C. Eringen Medal of the Society of Engineering Science . In 1984 he received the Tymoshenko Medal of the American Society of Mechanical Engineers (ASME) and in 1988 the National Medal of Science of the USA. The National Academy of Sciences honored him with the National Academy of Sciences Award in Applied Mathematics and Numerical Analysis in 1995 . In 1996 he received the Nemmers Prize for Mathematics and in 1997 the Wolf Prize for Mathematics. In 1994 he gave a plenary lecture at the International Congress of Mathematicians (ICM) in Zurich (Wave Propagation). He was a fellow of the American Mathematical Society .

Keller had been a member of the US National Academy of Sciences since 1973 . He has honorary degrees from the Technical University of Denmark , Northwestern University , the Technical University of Crete , the New Jersey Institute of Technology and Columbia University .

For his calculation of a teapot whose spout does not drip, he was awarded the Ig Nobel Prize in Physics in 1999. In 2012 he received the Ig Nobel Prize again for a work on the movement of a ponytail.
