WILSON E.L.

WILSON E.L. 05.09. 1931 Ferndale CA/USA 25.02. 2005 Haverhill MA/USA Edward (Ed) Lawrence Wilson received education from University of California, Berkeley CA, from where he graduated with the BS, MS, and D.Eng. degrees in 1955, 1959 and 1963, respectively. He was research engineer with Aerojet General Corp., Sacramento CA, until 1965, returning then to his Alma Mater from assistant professor to professor of civil engineering until retirement in 1988. He was a member of the American Society of Civil Engineers ASCE and elected in 1985 to the National Academy of Engineering NAE. He also was the recipient of the 2003 John von Neumann Award with the full citation ‘For his pioneering contributions to the Finite Element Method and the development of the SAP codes that were disseminated throughout the world, providing hundreds of institutions with their first finite element software’. Wilson was a notable engineer developing the Finite Element Method for applications in hydraulic or structural engineering. In the early 1960s, computer programs were developed all over the Western World and Japan. The first widely accepted program was the Structural Analysis Package SAP of Wilson. Most programs were written in FORTRAN, the only suitable language at the time. Soon there was a veritable explosion in programs and currently there are sources of packages which are menu-driven and automated to the extent that, with minimal training, anybody can do a finite element analysis for better of for worse.

WILSON H.M. 23.08. 1860 Glasgow/UK 25.11. 1920 Hartford CT/USA Herbert Michael Wilson obtained the degree in civil engineering in 1881 from Columbia University, New York NY. He then was levelman, transitman, and chief of party for railroad surveys in Mexico until 1882, taking over until 1888 as topographer of the US Geological Survey USGS, and then until 1890 being irrigation engineer, becoming geographer until 1906, from when he was chief engineer of structural and fuel testing until 1910. Until 1914 he was then engineer in charge of the US Bureau of Mines, and until 1918 served as director of the Department of Safety and Inspection of the Associated Companies, Hartford CT, from when he was its general manager. Wilson in parallel was Lecturer in irrigation at Columbia University from 1892 to 1893. He was member of the Washington Academy. Wilson was a true expert in civil and mining engineering, specialising in geography, irrigation engineering, safety of mining, and of insurance compensation. He has written a number of papers and books, among which is the Manual of irrigation engineering. It contains the chapters 1. Introduction, 2. Precipitation, runoff, and stream flow, 3. Seepage, Evaporation and absorption, 4. Alkali, drainage, and sedimentation, 5. Quantity of water required, 6. Flow and measurement of water in open channels, 7. Subsurface water, 8. Classes of irrigation works, 9. Alignment, slope, and cross-section, 10. Headworks and diversion weirs, 11. Scouring sluices, regulators, and escapes, 12. Falls and drainage works, 13. Distributaries, 14. Application of water, and pipe irrigation, 15. Reservoirs, 16. Earth and loose rock dams, 17. Masonry dams, 18. Wasteways and outlet sluices, and 19. Pumping, tools and maintenance. The work therefore includes all important aspects of irrigation engineering; previous books of similar content include these of Patrick J. Flynn (1838-1893), and Robert B. Buckley (1847-1927). The 7th edition co-authored by Arthur P. Davis (1861-1933) includes more than 600 pages as compared to the original 500 pages book of the 1898 version. Anonymous (1921). Wilson, H.M. American men of science 3: 749. Science Press: New York.
