From http://de.wikipedia.org/wiki/Henry_L._Langhaar :
Born 14 October 1909 in Oklahoma; Died 28 September 1992. Professor Langhaar was an American engineer scientist of Mechanics and Civil Engineering. He studied mechanics at Lehigh University, where he received his doctorate in 1940 under Clarence Albert Shook (Steady flow in the transition length of a cylindrical conduit). He became professor of mechanics at the University of Illinois at Urbana-Champaign. In 1979 he received the Theodore von Karman Medal.

ABSTRACT: An infinitesimal theory of instability of an elastic orthotropic shell of revolution subjected to uniform external normal pressure is developed. The theory leads to a linear eigenvalue problem for determination of the buckling pressure. Illustrative numerical calculations based on piecewise-polynomial approximations and the partition method are given for the Fort Martin tower erected in West Virginia by the Marley Co. The tower is a reinforced concrete hyperboloidal shell of revolution, 370 ft. high and 5.5 in. thick for most of its height.
