Frank J. Swetz (The Pennsylvania State University)

Johann Fredrick Penther (1693-1749) was a German mathematician and architect. In 1732 he published his Praxis geometriae, which remained a German language 18th century classic on the geometry of surveying. This image is of the title page for the fourth edition of 1752.

The frontispiece depicts Geometry as a queen whose counsel is sought.

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.
