Mathematical Treasure: Edmund Stone on Using the Sector

Frank J. Swetz (The Pennsylvania State University)

Edmund Stone was an 18th-century self-educated Scottish mathematician. In 1729 he published a revised edition of Samuel Cunn’s A New Treatise of the Construction and Use of the Sector. Cunn (flourished 1714–1722) was a London surveyor and teacher of mathematics. The title page of the book follows.

A diagram of the sector (on the page facing the title page) advertised the instrument-making business of one of the sponsors and sellers of the book, Thomas Heath.

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.
