The first PhD awarded by OSU Dept of Geodetic Science was to C. E. Ewing in 1955. Ewing wrote a thesis "The parallel radius method of solving the inverse Shoran problem". At that time the GS Department was known as Institute of Geodesy, Photogrammetry & Cartography, under the Dept of Geology. Ewing's work was under the guidance of four geodesy mentors at OSU - WA Heiskanen, FJ Doyle, RA Hirvonen & Simon Laurila.
The main body of the thesis written by Ewing consists of 74 pages only. It has many computation results and table with total of 230 pages. Glancing through the references (or written as Bibliography) only sixteen materials were included. Out of that only two text books on Geodesy were cited - Geodesy by Bomford (1952 - 454 pages) and Geodesy by George L Hosmer (1929 - 461 pages). The rest of the references were geodesy reports from Finland and OSU and a number of publications only.
That shows geodesy in the early 1950s was really a discipline with very few textbooks and journal papers available. And the means to access to the materials at that time is merely by personal correspondence to authors.
Ewing was born in September 1915. He obtained a BSc in CE from Kansas in 1941 and MSc CE from Colorado in 1950. He work with US Army.
