Geometrical drawing

This collection contains materials that belonged to John Ehresman, a student who attended the Purdue Preparatory School in 1893-94 and attended Purdue University during the 1894-1896 academic years. Items include class notes, personal essays, commonplace book, engineering drawings and lab notes. This collection will be helpful to researchers interested in Purdue's early mechanical engineering education curriculum and farming practices of the late 1800s.
