Jack Dangermond is an American business executive and environmental scientist. In 1969, he co-founded with his wife Laura the Environmental Systems Research Institute (Esri), a privately-held Geographic Information Systems (GIS) software company. In 2009, with an estimated net worth of $2 billion, Dangermond joined the Forbes 400 list of richest Americans. Dangermond is the company's President and Chief Executive Officer and works out of Esri's headquarters in Redlands, California. Dangermond founded Esri to perform land use analysis, however its focus evolved into GIS software development, highlighted by the release of Arc/INFO in the early 1980s; the development and marketing of Arc/INFO positioned Esri with the dominant market share among GIS software developers. Today Esri is the largest GIS software developer in the world and its flagship product, ArcGIS traces its heritage to Dangermond's initial efforts in developing Arc/INFO.
