Ernest Edwin Sechler was an aerospace engineer and scientist who specialized in thin-shell structures. He earned his doctorate in 1934 at Caltech as one of the early students of Theodore von Kármán with a dissertation on the mechanics of thin-plate compression.
Sechler contributed to the transition from wood to metal for construction of airframes.
Von Kármán showed that by stiffening with re-enforcing strips the "effective width" of metal sheets could be increased to withstand the load aloft. In 1934 Sechler wrote his thesis, The ultimate compressive strength of thin sheet metal panels, under von Karman’s supervision.
"Development of light, fail-safe structure became the main theme of his professional life." His thin-wall structures included missiles, booster rockets, and a movable dome for Palomar Observatory. This work was performed as consultant to NASA and industry.
Sechler wrote two of the standard references on shell structures, Airplane Structural Analysis and Design (1942, with L. G. Dunn) and Elasticity in Engineering (1952). William Fuller Brown, Jr., reviewed Elasticity in Engineering for Physics Today (February 1954, page 22). Generally favorable, Brown gives some suggestions, saying "Some of the most basic topics are discussed least clearly." E.W. Hammer reviewed it in Journal of the Franklin Institute (255(3):252). He outlined the book's contents and concludes "many practical examples have been included to illustrate the various methods of structural analysis."
Sechler was responsible for the aeronautics graduate education at the Guggenheim Aeronautical Laboratory. He had "an unbelievable intuitive understanding of the potential of an incoming student."
