Frank J. Swetz (The Pennsylvania State University)

Christian Wolff (1679-1754) was a German philosopher and mathematician. His Trigonometrie (1711) was a collection of logarithmic tables for sine and tangent.

Erwin Tomash (1921-2012) was a pioneering computer scientist, helping launch the U.S. computer industry from the 1940s onward. During the 1970s he became interested in the history of computer science, and founded the Charles Babbage Society, and its research arm, the Charles Babbage Institute. The Institute, an archive and research center, is housed at the University of Minnesota. Its Erwin Tomash Library on the History of Computing began with Tomash's 2009 donation to the Institute of much of his own collection of rare books from the history of mathematics and computing.
