Pocket Cases

A Eugene Dietzgen Company set of drawing instruments.

This page displays the earliest sets in the mathematics collections. The coverings on the cases are sharkskin or tortoiseshell. Notable European makers crafted some of the instruments in these cases, including Pierre Martel, Michael Butterfield, Claude Langlois, and Thomas Rubergall. At least one of these sets is known to have been used in the early United States.
