Gerard Hendrik Matthes was born on March 16, 1874 in Amsterdam, the Netherlands. He was the son of Wille Ernest Matthes and Johanna van der Does. Matthes' parents immigrated into the United States in 1888, settling in Los Angeles, Calif. , where the father became a businessman.
Gerard and his twin brother remained in Europe to complete their education. They studied at private schools in the Netherlands and Switzerland, and graduated from gymnasium at Frankfurt-am-Main in 1891. That year both immigrated to the United States to enter the Massachusetts Institute of Technology (MIT). Matthes graduated from MIT in 1895 and began his career as a surveyor of watercourses.
He was an instrument man and draftsman for the town of Brookline, Massachussets, while surveying Boston Harbor and the Connecticut River for the Massachusetts State Board of Harbor and Land Commissioners. After two years Matthes joined the U. S. Geological Survey as an assistant hydrographer. In that capacity he did stream gauging and irrigation studies. In 1902 he became district engineer in charge of the construction works in Comanche, Caddo, and Kiowa counties in the Oklahoma Territory. He had, the year earlier, taken time off to go to Sumatra with an MIT astronomical expedition. Matthes became the assistant supervising engineer for the U. S. Reclamation Service in New Mexico and Idaho in 1905. His work mainly concerned irrigation projects. This position lasted two years. Matthes next worked for four years (1907 - 1911) as designing engineer, resident engineer, and superintendent of construction for the Colorado Power Company, which was developing the upper Colorado River. In 1911, Matthes was appointed principal assistant engineer for the American Water Works and Guaranty Company, which was involved with power development of the Cheat River in West Virginia. Following this two-year stint he spent two years as a division engineer for the Pennsylvania Water Supply Commission. He then became a hydraulic engineer with the Miami Conservancy District, headquartered in Dayton, Ohio, doing flood control for the Miami River Valley. Matthes joined the War Department in 1920 as an assistant engineer, with a principal assignment of surveying the Tennessee River. In this capacity he used aerial photographs to map the river, the first such use by the War Department. Sensing the potential of this technique, Matthes left federal service in 1923 to open a private consulting engineering practice in New York City. He returned to government work in 1929 as senior hydroelectric engineer, then principal engineer, in the Army Engineer Office at Norfolk, Va. In this capacity he studied rivers in Virginia and North Carolina. He also began his work as a consultant to other federal projects, an involvement that increased considerably as the New Deal expanded public works construction. In 1932, Matthes became principal engineer, head engineer, and consultant to the Mississippi River Commission in Vicksburg, Miss. , an organization dedicated to flood control and improved navigation on the lower Mississippi River. He also was a consultant on flood control for the Tennessee Valley Authority in 1936, and head engineer and director of the U. S. Waterways Experiment Station in Vicksburg from 1942 to 1945. Matthes retired in 1945 but did not cease work. Matthes died on April 8, 1959 in New York City.
For his dual wartime service Matthes received the Gold Medal for Exceptional Civilian Service in 1944. He created the Rocky Mountain Hydraulic Laboratory in Allens Park, Colo. , a nonprofit research laboratory specializing in river and flood analysis. He also continued a private consultancy practice in New York City that extended to Latin America. He received a patent for a tetrahedral block revetment for riverbanks in 1946.
