FLAD

FLAD 30.07. 1824 Rennhof/D 20.06. 1898 Pittsburgh PA/USA Henry (Heinrich) Flad was born in Bavaria; he graduated in 1846 from the University of Munich and then served in the Bavarian Army during the German revolution of 1848. He fled to the USA in 1849, engaged until 1860 as a railroad engineer. He served from private to colonel in the US Army during the Civil War, becoming then construction assistant to James B. Eads (1820-1887), during which period the Eads Bridge over Mississippi River was completed. Flad was from 1868 to 1876 a member of the Board of the Water Commission of St. Louis MO, during which time the city waterworks were completed. He was a member of the American Society of Civil Engineers ASCE, presiding over it in 1866. He also was a founder of the Engineers Club of St. Louis, serving from 1868 to 1880 as its president. During the Civil War Flad had participated in civil construction. Once serving for Eads he developed measurement methods as a member of the Mississippi River Commission. In connection with James P. Kirkwood (1807-1877), Flad prepared plans for the old waterworks at Bissell’s Point, St. Louis, forming a solid basis of the present magnificent system. The construction of Eads’ Bridge demonstrated the great ability and fertility of resource to apply scientific principles to the mastery of engineering problems placed him in the estimation of engineers. Flad was elected the first president of the Board of Public Improvements of St. Louis in 1877, and resigned only in 1890 when accepting from the President of the United States the appointment of member of the Mississippi River Commission. Taking into account his outstanding ability, Flad’s simplicity of character was grand. He was without guile and deceit, and it was always difficult with him to believe that it existed in others with whom he was brought into contact. Nothing but indisputable evidence of deception brought him to believe that he had been wronged. And then it provoked no animosity, nor would he give vent in strong language of condemnation, but there would come from him expression of sadness, as though something had happened which moved his soul in sorrow.

FLINN 04.08. 1869 New Berlin PA/USA 14.03. 1937 Scarsdale NY/USA Alfred Douglas Flinn obtained the BS degree from Worcester Polytechnic Institute, Worcester MA in 1893. He was awarded the Honorary Doctorate of applied science by the University of Louvain, Belgium in 1927. He was from 1895 engineer with the Metropolitan Water Works, Boston MA, from 1902 to 1904 then managing editor of the journal Engineering News, New York, and engineer of the Croton Aqueduct Commission, New York until 1905, from when he took over until 1918 as deputy chief engineer the Board of Water Supply of New York City, namely the Catskill Aqueduct. He was until 1934 secretary of the United Engineering Trustee, Inc. He had previously also served as secretary of the Engineering Council and had been in the early 1920s director of the Engineering Foundation. He was from 1918 to 1923 member of the National Research Council, and chairman of its Engineering Division. Flinn was a Knight of the Order of the White Lion, the Republic of Czechoslovakia. He was a member ASCE. Flinn devoted his professional career mainly to water supply and water distribution in urban areas. His 1894 paper deals with a trapezoidal weir invented by the Italian Cesare Cipolletti (1843-1908) by which the head-discharge relation becomes particularly simple, so that this hydraulic structure was of relevance in irrigation techniques. The experiments were conducted at the Water Power Company, Holyoke MA, under the direction of Clemens Herschel (1842-1930). It was found that the weir studied has a performance similar to the standard rectangular thin-plate weir. Flinn was an author of the book Waterworks handbook with Robert S. Weston (1869-1943). Its main chapters are 1. Sources of water supply, 2. Collection of water, 3. Transportation and delivery of water, 4. Distribution of water, and 5. Character and treatment of water. Anonymous (1918).
