Tom Mike Apostol (August 20, 1923 - May 8, 2016) was an American  analytic number theorist and professor at the California Institute of Technology, best known as the author of widely used mathematical textbooks.
Life and career
Apostol was born in
Helper, Utah. His parents, Emmanouil Apostolopoulos and Efrosini Papathanasopoulos, were Greek immigrants. Apostolopoulos's name was shortened to Mike Apostol when he obtained his United States citizenship, and Tom Apostol inherited this  Americanized surname. 
Apostol received his
Bachelor of Science in chemical engineering in 1944, Master's degree in mathematics from the University of Washington in 1946, and a PhD in mathematics from the University of California, Berkeley in 1948. Since then Apostol was a faculty member at UC Berkeley,  MIT, and Caltech. He was the author of several influential graduate and undergraduate level textbooks.
Apostol was the creator and project director for
Project MATHEMATICS! producing videos which explore basic topics in high school mathematics. He helped popularize the visual calculus devised by Mamikon Mnatsakanian with whom he also wrote a number of papers, many of which appeared in the . Apostol also provided academic content for an acclaimed video lecture series on introductory physics, American Mathematical Monthly .
The Mechanical Universe
In 2001, Apostol was elected in the
Academy of Athens.  He received a  Lester R. Ford Award in 2005,   in 2008,  and in 2010.  In 2012 he became a fellow of the  American Mathematical Society.
