1959 Henry Emmett Gross City Plan or Map of St. Louis, Missouri

Henry Emmett Gross (August 8, 1906 - April 3, 1982) was an American engineer and map publisher. Born in Glendale, Missouri, in 1928 Gross received a bachelor's degree in engineering from the Missouri School of Mines and then went on to receive a master's degree in engineering from the University of Illinois. From 1936 until 1938, Gross taught petroleum engineering at the University of Oklahoma and then taught the same subject at Texas A and M from 1938 until 1942. During World War II, Gross lived in Chicago and directed the district engineering office of the federal government's Petroleum Administration for War. In 1945, Gross became the chief production engineer of the Kingwood Oil Company in Effingham, Illinois. However, he left a year later to take over the Gross Map Company in St. Louis. He owned and operated the Gross Map Company (which published maps of the St. Louis area) from 1946 until 1973 when he retired. The map company closed upon his retirement. Gross patented several inventions during his life, including a marine foundation for deep-water oil drilling and deep-sea salvage equipment for raising sunken ships, for which he became an honorary member of the Explorers Club. He married his wife, the former Margrete Brauer, in 1941 in Norman, Oklahoma. More by this mapmaker...
