Contents
Life
Henrici was born in Basel and studied law for two years at University of Basel. After World War II he transferred to ETH Zürich where he received a diploma in electrical engineering (1948) and a doctorate in mathematics with Eduard Stiefel as his advisor (1952).
Moving to the USA
In 1951 he moved to the United States and worked on a joint contract with American University and the National Bureau of Standards. Then, from 1956 to 1962, he taught at University of California, Los Angeles where he became a professor. In 1962 he returned to ETH Zürich as a professor, a position he kept for the rest of his life, though he also held a parttime appointment as William R. Kenan, Jr. Distinguished Professor of Mathematics at the University of North Carolina at Chapel Hill from 1985.^{[1]}^{[2]}
Numerical Analyst
An internationally recognized numerical analyst, who published 11 books and more than 80 research papers, Henrici was also a gifted pianist and a highly regarded teacher.^{[1]} He was an editor of a number of scientific journals, including Numerische Mathematik and Zeitschrift für Angewandte Mathematik und Physik. In 1962, he was a speaker at the International Congress of Mathematicians, and in 1978 he gave the SIAM John von Neumann Lecture.^{[2]}
Peter Henrici Prize
Every four years since 1999, the Peter Henrici Prize is awarded by ETH Zürich and SIAM for "original contributions to applied analysis and numerical analysis and/or for exposition appropriate for applied mathematics and scientific computing".^{[3]}
