The person who coined the term "cypherpunks" is the one most people can name.
Judith Milhon called herself St. Jude. She was a self-taught programmer in Berkeley, and in the early 1990s she coined the word cypherpunk, stitching together cyberpunk and cipher. It was in print within months. Every person who has ever used the word is quoting her.
Twenty years before that, in 1973, she helped build Community Memory. A public terminal in a Berkeley record store that anyone could walk up to and post on. No account, no permission, no gatekeeper deciding whose message counted.
Nice fact. I didn't know this.
