NICHOLAS C. MANDRAGOS PAPERS, 1927-1959, #484

By Don Darroch September 9, 1993

History

Nicholas C. Mandragos was born on the Greek island of Symi in 1896 and was educated at the Salvago Professional School in Alexandria, Egypt, at New York University and at Brooklyn Polytechnic Institute. He received a bachelor of science degree in engineering at the latter institution plus 21 points of graduate studies. After being employed as a structural engineer by New York Central Railroad, 1926-1937, Mandragos was employed in research during World War II at the War and Navy Departments. He also lectured on photo elasticity at George Washington University 1943-1949 and was an associate professor there 1947-1949; later he was a consulting engineer.

Scope and Content

The collection consists almost entirely of notes Mandragos used as the basis for lectures to his engineering classes. They cover various problem areas: stress analysis of structures, strength of materials, hydraulics and other technical aspects of structural design. There are also a few notes Mandragos made as a student in the 1920s and 1930s. The notes are carefully hand-printed with detailed technical drawings, sometimes in photocopy. They are arranged alphabetically by subject, usually with dates.

Provenance

This material was donated to NMAH, together with several instruments and models relating to materials testing, in October 1992 by Mr. Mandragos' widow, Frieda Mandragos. The instruments and models were retained by the Division of Engineering and Industry and the papers were transferred to the Archives Center 4/15/1993.
