Mathematical Treasure: Descriptive Geometry by Ames and Wischmeyer

Descriptive Geometry (5th edition, 1918), by William L. Ames (b. 1855) and Carl W. Wischmeyer, was first published in 1893 as Ames’s solely-authored Notes on Descriptive Geometry. Note the authors’ association with “machine design”; indeed, Ames, who taught at what is now Rose-Holman Institute of Technology in Terre Haute, IN, from 1883 to 1906, is known for introducing third-angle projection into this subject associated with mechanical engineering. He briefly joined the faculty of Worcester Polytechnic Institute before working for the Reed & Prince Manufacturing Company in Worcester from 1899 to 1919, at which time he retired to New York City. Wischmeyer graduated from Rose in 1906 and taught there from 1908 to 1955. His son, Carl R. Wischmeyer (ca 1906–2009), became a long-time professor of electrical engineering at Rice University.
