Lewis Ferry Moody (5 January 1880 – 18 April 1953[1]) was an American engineer and professor, best known for the Moody chart, a diagram capturing relationships between several variables used in calculating fluid flow through a pipe. He has 23 patents for his inventions.[2] He was the first Professor of Hydraulics in the School of Engineering at Princeton.[3]
He was born on 5 January 1880.
Lewis F. Moody as professor of fluid mechanics and machine design taught at Princeton University starting in 1930.[4] He co-wrote the book Fifty Years’ Progress in Hydraulics with fellow engineer Blake R. Van Leer.[5]
He married Eleanor Greene. His wife died in 1937.[6] His daughter, Eleanor Lowry Moody, married in 1944.[7] He was awarded the Elliott Cresson Medal in 1945.

He died on 18 April 1953.
Five years after his death, ASME created an Award to his honours: The Lewis F. Moody award, which is awarded for outstanding original papers useful to the practice of mechanical engineering by the Fluids Engineering Division (FED).[9]
