Jack K. Hale

Jack Kenneth Hale (3 October 1928 – 9 December 2009) was an American mathematician working primarily in the field of dynamical systems and functional differential equations. his undergraduate years were spent at Berea College, where he was studying Mathematics until 1949.

In 1954–57, Hale worked as a Systems Analyst at Sandia Corporation and in 1957–58 he was a staff scientist at Remington Rand Univac. of which he was later Chief Editor. The following year he shared the 1965 Chauvenet Prize with LaSalle for their exposition in the piece on Differential Equations: Linearity vs. Nonlinearity published in the SIAM Review. In 1999 he received an honorary doctorate from the University of Rostock (Germany).

Throughout his career, Hale published 15 books, over 200 research papers, and supervised 48 Ph.D. students. He was an Honorary Fellow of the Royal Society of Edinburgh, a Corresponding Member of the Brazilian Academy of Sciences, and a Foreign Member of the Polish Academy of Sciences.
