Garry Newman (Born May 20, 1982  in England) is the creator of Garry's Mod and owner of Facepunch Studios. He created Garry's Mod in 2004 and and has a total of 16000 hours in-game. He has retired entirely from playing Garry's Mod, opting instead to play Facepunch's other popular game, Rust, thus making the achievement "Yes, I am the real Garry!" impossible to obtain.
Garry has worked on other games, such as Rust, Clatter and Chippy.
Garry Newman's current project is a new sandbox game called "S&Box", which is designed as a sequel to Garry's Mod being developed on Valve's Source 2 game engine, the same engine that Half-Life: Alyx  runs on.
Garry Newman applied for a job at Valve at some point before Garry's Mod went on sale. Garry had a phone interview, but did not continue with any more interviews because Valve was no longer interested.
Garry Newman has not personally worked on a Garry's Mod update in years.
