Caldwell, Samuel Hawks was born on January 15, 1904 in Philadelphia, Pennsylvania, United States. Son of Thomas B. and Margaret L. (Hogg) Caldwell.
He completed all his degrees in electrical engineering at Massachusetts Institute of Technology. His Doctor of Science., advised by Bush, was entitled The Extension and Application of Differential Analyzer Technique in the Solution of Ordinary Differential Equations (1933).
His Master of Science thesis was entitled Electrical characteristics and theory of operation of a dry electrolytic rectifier (1926). In his doctoral studies he worked on analog computers with Vannevar Bush, developing the Differential Analyzer. He then joined the faculty of the electrical engineering department.
During World World War II he was on the National Defense Research Committee.
After the war, he led the Massachusetts Institute of Technology Center of Analysis, where he reluctantly gave way to digital computing by initiating the Rockefeller Electronic Computer (RED) and supporting the Project Whirlwind. The centre closed around 1950, after which Caldwell continued as a faculty member, being the advisor to both David A. Huffman (1953) and Edward J. McCluskey (1956).
Fellow American Association Advancement Science. Member American Institute of Elctrical Engineering, American Association for the Advancement of Science, Sigma Xi, Eta Kappa Nu. Clubs: Saint Botolph (Boston).
