Joseph

Bishop Keller (July 31, 1923 –

September 7, 2016) was an American mathematician who specialized in applied mathematics. He

was best known for his work on the "geometrical theory of

diffraction" (GTD). Born

in Paterson, New Jersey on

July 31, 1923, Keller attended Eastside

High School, where he was a member of the math team. After

earning his undergraduate degree in 1943 at New York University,

Keller obtained his PhD in 1948 from NYU under the supervision of Richard Courant. He was a Professor of Mathematics in

the Courant Institute at

New York University until 1979. Then he was Professor of Mathematics and

Mechanical Engineering at Stanford University until

1993, when he became Professor Emeritus. Keller

worked on the application of mathematics to problems in science and

engineering, such as wave propagation. He contributed to computing eigenvalues in quantum mechanical systems. Keller was awarded a Lester R. Ford Award (shared

with David W. McLaughlin) in 1976 and (not shared) in 1977. In 1988

he was awarded the U.S. National Medal of Science,

and in 1997 he was awarded the Wolf Prize by the Israel-based Wolf Foundation. In 1996, he was awarded the Nemmers Prize in

Mathematics. In 1999 he was awarded the Ig Nobel Prize for calculating how to make a teapot spout

that does not drip. With Patrick B. Warren, Robin C. Ball and Raymond E. Goldstein,

Keller was awarded an Ig Nobel Prize in 2012 for calculating the forces that

shape and move ponytail hair. This makes him

the only person to win more than one Ig Nobel Prize. In 2012 he became a fellow

of the American Mathematical

Society.
