Mansfield Merriman (1848-1925)
Merriman, a well-known civil engineer, was a "true" civil engineer in his professional diversity: hydraulics, bridge design (served on the design commission of New York City's Manhattan Bridge), construction, and author of many civil engineering books (Treatise on Hydraulics, A Textbook on Roofs and Bridges, Mechanics of Materials, Elements of Sanitary Engineering, American Civil Engineers' Pocketbook, to name a few) was a professor of civil and mechanical engineering at Lehigh from 1878-1881, and head of the Department of Civil Engineering from 1881 to 1907. He established the first hydraulics lab in America under college auspices at Lehigh in 1887. He and his students performed pioneering research in hydraulics including the phenomenon of the "hydraulic jump" in an old building on the hillside by Williams Hall.
Mansfield Merriman's son, Thaddeus Merriman (Class of 1897) followed in his father's footsteps as a civil engineer and engineered the monumental water tunnels that brought water to New York City and Los Angeles.
