Jack Dangermond OON (born 1945) is an American billionaire businessman and environmental scientist, who co-founded, with Laura Dangermond, in 1969 the Environmental Systems Research Institute (Esri), a privately held geographic information systems (GIS) software company.
Dangermond, the Esri's president, works at its headquarters in Redlands, California. He founded the company 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. As of 2020[update] Esri is the largest GIS-software developer in the world; its flagship product, ArcGIS, traces its heritage to Dangermond's initial efforts in developing ARC/INFO.
Dangermond completed his undergraduate degree in landscape architecture at California State Polytechnic University, Pomona. He then earned a Master in Urban Planning from the University of Minnesota, and a Master of Landscape Architecture degree from the Harvard University Graduate School of Design in 1969. His early work in the school's Laboratory for Computer Graphics and Spatial Analysis (LCGSA) led directly to the development of Esri's ARC/INFO GIS software. He has been awarded 13 honorary doctoral degrees.
In December 2017, Jack and Laura Dangermond donated $165 million to establish the Jack and Laura Dangermond Preserve on the Pacific coast—the largest ever gift to The Nature Conservancy.
Jack and Laura Dangermond have signed The Giving Pledge.
In January 2020, Jack and Laura Dangermond donated $3 million to the Museum of Redlands fund.
