Homebrew Computer Club

The Homebrew Computer Club was an early computer hobbyist group in Menlo Park, California, which met from March 1975 to December 1986. The club played an influential role in the development of the microcomputer revolution and the rise of that aspect of the Silicon Valley information technology industrial complex.

Several high-profile hackers and computer entrepreneurs emerged from its ranks, including Steve Jobs and Steve Wozniak, the founders of Apple Computer. With its newsletter and monthly meetings promoting an open exchange of ideas, the club has been described as "the crucible for an entire industry" as it pertains to personal computing[1]
