First authored by OConnor- John Charles Lounsbury Fish (June 3, 1870 - June 15, 1962) was a Professor of Civil Engineering, Emeritus, at the School of Engineering, Stanford University. He is known for his works Mathematics of the Paper Location of a Railroad (1905), Earthwork Haul and Overhaul: Including Economic Distribution (1913), Technique of Surveying Instruments and Methods (1917), Engineering Economics: First Principles... (1923), The Engineering Method (1950), Linear Drawing and Lettering for Beginners, Lettering of Working Drawings, and Descriptive Geometry, and also as a coauthor of Technic of Surveying Instruments and Methods (with Walter Loring Webb, 1917), The Transition Curve... (with Charles Lee Crandall), and The Engineering Profession (with Theodore Jesse Hoover, 1941).

Fish provided the critical bridge between the pioneering effort of Arthur M. Wellington in his engineering economics work of the 1870s and the first publication of the Principles of Engineering Economy in 1930 by Eugene L. Grant.
