John Burdette Gage (born 1942) was the 21st employee of Sun Microsystems, where he is credited with creating the phrase "the network is the computer." He served as Chief Researcher and Vice President of the Science Office for Sun, until leaving on June 9, 2008 to join Kleiner Perkins as a partner to work on green technologies for global warming; he departed KPCB in 2010 to apply what he had learned "to broader issues in other parts of the world". He is also best known as one of the co-founders of NetDay in 1995.
Gage received his bachelor's degree in 1975 from the University of California, Berkeley. He also attended the Harvard Kennedy School of Government, and the Harvard Business School. While at Berkeley, he was a leader in the anti-war movement and was a delegate for Robert Kennedy in 1968 for the Democratic National Convention in Chicago, representing Berkeley and Alameda County, California. He co-chaired the Robert Kennedy campaign in Alameda County. Gage had worked at Berkeley with Bill Joy, the person largely responsible for the authorship of Berkeley UNIX, also known as BSD, from which springs many modern forms of UNIX, including Solaris, FreeBSD, NetBSD, and OpenBSD. Gage joined Sun Microsystems in 1982 with Bill Joy and others.
In April, 2002, Gage joined the Markle Taskforce on National Security in the Information Age, whose two reports explore how federal, state and local governments collect, analyze and use information as it relates to national security and homeland defense. Their two reports, when joined with the reports of the 9/11 Commission and the WMD Commission Report, formed the foundation for the 2004-2005 reforms of the intelligence and homeland security communities.
