M. H. McAndrew

M. H. McAndrew was a mathematician at IBM Research, co-author of the 1965 paper Topological Entropy with Roy Adler and Alan Konheim. The paper, published in the Transactions of the American Mathematical Society, introduced the first rigorous definition of topological entropy and established the foundation for the topological theory of dynamical systems.

Little is publicly known of McAndrew's biography beyond this collaboration. In the mathematics of the 1960s, it was common for researchers at industrial laboratories to publish foundational work that would be remembered for the theorems rather than the individuals. McAndrew's case exemplifies this pattern: the definition of topological entropy is universally cited, but McAndrew himself is rarely mentioned outside the author list of the original paper.
