Crocker was a general civil engineer with a specialization mainly in irrigation and water supply projects. He also served on various State Boards to improve river conditions and to control flood flows. He had a particular relation to the American Society of Civil Engineers ASCE, serving as director from 1917 to 1919, vice-president in 1920, acting secretary from 1919 to 1929, and finally ASCE President in 1932 during the difficult early 1930s, becoming honorary member in 1939. He further was member of the ASCE Colorado Section, and the Texas Section, and was member of the Western Society of Civil Engineers, among many others. Anonymous (1932). Herbert S.

CROES 25.11. 1834 Richmond VA/USA 17.03. 1906 Yonkers NY/USA John James Robertson Croes graduated as a civil engineer from St. James College, Hagerstown MD in 1853. He started his civil engineering practice in 1856, assisting first James Pugh Kirkwood (18071877) in the construction of Ridgewood Reservoir of the Brooklyn Waterworks, then resident engineer of the first high masonry dam in the USA at Boyd’s Corner NY from 1865 to 1870, with his 1874 paper being awarded the first Norman Medal from ASCE. He then became topographical engineer for the New York Park Department until 1878. In the 1880s he made expert reports on the Quaker Bridge Dam, a part of New York Aqueduct, and later on the New Croton Dam of the same scheme. From 1903 Croes was a consulting engineer of the New York Health Department. He was a member of the American Society of Civil Engineers ASCE, serving as treasurer from 1877 to 1887, and as ASCE president in 1901. From 1882 he was a member of the Institution of Civil Engineers, London, the American Public Health Association, and the New England Water Works Association. Croes is known for a large number of reports mainly as an expert of hydraulic schemes. His works related principally to questions on water supply and sewage works. These include the water supply of Newark and Syracuse NY, or the design and construction of waterworks in Indianapolis IN. He also contributed a paper on the History of American water works. He was further associated with the journal Sanitary Engineer, for which he regularly submitted editorials. His 1891 report relates to the dam break at Johnstown PA, resulting in a large loss of lives and goods. ASCE’s John James Robertson Croes Medal was established in 1912. It is awarded annually to the Author of a paper published by ASCE journals for its merits as a contribution to engineering science. Anonymous (1905). Croes, John J.R. Who’s who in America 4: 338.
