William H. Latham (1903-1987) was a Consulting Park Engineer under Robert Moses, and one of the few aides with whom Moses would directly interact. Born in 1903, Latham graduated from the Massachusetts Institute of Technology with a degree in civil engineering. Hired by Moses in 1927, Latham, along with several other associates hired during that period known as the “Moses Men,” became legendary throughout state and city government for his ability, loyalty and determination. In 1954, Moses selected Latham to oversee construction of the Niagara Project, a hydroelectric dam on the St. Lawrence River in Lewiston, N.Y.; it was the world's largest such project at the time. Latham remained as the dam's resident engineer until his retirement in 1971.
