Allen Hazen

C. Winslow observes:

"Allen Hazen was of very different mold. Tall, angular, somewhat precise and pedantic, he had a mind which I think might fairly class him as an intellectual giant. Even before taking his degree at MIT he assisted Hiram F. Mills in preparing the plans for the Lawrence filter, and he was in charge of the Lawrence Experiment Station from 1888 to 1893. He developed the procedures for the mechanical analysis of sand, in use to this day. He planned the sewage disposal system for the Chicago Exposition in 1893. As a consulting engineer in Boston and later in New York he built the Albany (N.Y.) filter and consulted with many municipalities (including Brisbane, Australia) on water problems. His studies on hydraulics, on hydrography, and the runoff of streams were basic in the development of these areas of engineering."
