Eric Freeman is a computer scientist with a passion for media and software architectures and coauthor of Head First Design Patterns. He just wrapped up four years at a dream job– directing internet broadband and wireless efforts at Disney–and is now back to writing, creating cool software, and hacking Java and Macs.Eric spent a lot of the ’90s working on alternatives to the desktop metaphor with David Gelernter (and they’re both still asking the question, “Why do I have to give a file a name?”). Based on this work, Eric landed a Ph.D. at Yale University in 1997. He also co-founded Mirror Worlds Technologies (now acquired) to create a commercial version of his thesis work, Lifestreams.
