Mansfield Merriman

Mansfield Merriman (1848-1925) was an American civil engineer, born at Southington, Conn. He graduated at Sheffield Scientific School (Yale) in 1871, was assistant in the United States Corps of Engineers in 1872-73, and instructor in civil engineering at Sheffield from 1875 to 1878. He was professor of civil engineering in Lehigh University from 1878 to 1907 and thereafter a consulting civil and hydraulic engineer. From 1880 to 1885 he was also assistant on the United States Coast and Geodetic Survey. His researches in hydraulics, bridges, strength of materials, and pure mathematics are important. His chief publications, many of them widely used as textbooks, are:

• Method of Least Squares (1884; eighth edition, 1901)
• Mechanics of Materials (1885; tenth edition, 1912)
• with Jacoby, A Text-Book on Roofs and Bridges (four volumes, 1888-98; fifth edition, 1912)
• Treatise on Hydraulics (1889; ninth edition, 1914)
• Handbook for Surveyors (1895; third edition, 1903)
• Strength of Materials (1897; sixth edition, 1913)
• Precise Sanitary Engineering (1898; third edition, 1906)
• The solution of equations (1906)
• Elements of Hydraulics (1912)
• Recreations in Mathematics (1917), under the pseudonym of H. E. Licks

In addition, he was editor in chief of the American Civil Engineers' Pocket Book (1911). He is believed to have been the author of the Diaphote Hoax of 1880, a detailed newspaper report of a scientific demonstration of a device that transmitted images by electricity.
