Evans Hall is the statistics, economics, and mathematics building at the University of California, Berkeley.
Evans Hall also served as the gateway for the entire west coast's ARPAnet access during the early stages of the Internet's existence; at the time, the backbone was a 56kbit/s line to Chicago.
Because of its proximity to the engineering school, and the location of both the departments of Computer Science, and Mathematics, Evans Hall was the building in which the original vi text editor was programmed., as well as the birthplace of Berkeley Unix (BSD), and Rogue, which was further developed there by Glenn C Wickman, and Michael Toy. Rogue's origins included the curses library, which Rogue was originally written to test. Additionally, both Ingres and Postgres were originally coded in Evans, under Prof. Mike Stonebraker's direction.
The office of Professor Doug Cooper, who wrote the widely used programming textbook "Oh! Pascal!", was in this building.
In addition there is a basement computing facility often referred to as "The Dungeon." The printers are named with various underworld overtones such as Styx, Cerberus, and Charon, as well as The Unaprinter, presumably in reference to Ted Kaczynski's short tenure at Berkeley.
Evans Hall is situated at the northeast corner of campus, just east of Memorial Glade. It was built in 1971 and is named after Griffith C. Evans, chairman of mathematics from 1934 to 1949 who combined the fields of mathematics and economics. The architect was Gardner A. Dailey.
In the 1990s, this building saw significant renovation including seismic retrofits and a new paint job. Today, the building sports a blue-green exterior with orange-red accents.
