Henry Morgan Ward[1] (August 20, 1901 – June 26, 1963) was an American mathematician, a professor of mathematics at the California Institute of Technology.
He obtained his Ph.D. in mathematics from Caltech in 1928,[3] with a dissertation titled The Foundations of General Arithmetic; his advisor was Eric Temple Bell.
[4] Ward is the academic ancestor of over 500 mathematicians and computer scientists through Dilworth and another of his students, Donald A.
[4] Ward's research interests included the study of recurrence relations and the divisibility properties of their solutions, diophantine equations including Euler's sum of powers conjecture and equations between monomials, abstract algebra, lattice theory and residuated lattices, functional equations and functional iteration, and numerical analysis.
[6] Ward quasigroups are named after him, following his paper on alternative set of group axioms.
