Eric Steven Raymond (born December 4, 1957), often referred to as ESR, is an American software developer, open-source software advocate, and author of the 1997 essay and 1999 book The Cathedral and the Bazaar. He wrote a guidebook for the Roguelike game NetHack. In the 1990s, he edited and updated the Jargon File, published as The New Hacker's Dictionary.

Early life
Raymond was born in Boston, Massachusetts in 1957, and lived in Venezuela as a child. His family moved to Pennsylvania in 1971. He developed cerebral palsy at birth; his weakened physical condition motivated him to go into computing.
Career
Raymond began his programming career writing proprietary software, between 1980 and 1985. In 1990, noting that the Jargon File had not been maintained since about 1983, he adopted it, but not without criticism; Paul Dourish maintains an archived original version of the Jargon File, because, he says, Raymond's updates "essentially destroyed what held it together."
