Alan B. Oppenheimer graduated from M.I.T in 1983, writing his thesis on a new networking technology called Ethernet. Upon arriving at Apple Computer, he became part of a team working to create the network for a new computer called the Macintosh. Alan was responsible for many of AppleTalk's protocols, in both the Macintosh and the LaserWriter printer. Alan also worked on AppleShare, the Apple Internet Router and Apple Remote Access, and is a co-author of the book Inside AppleTalk, the definitive reference on the AppleTalk network system.
Alan left Apple to found Open Door Networks, Inc. in January 1995. In addition to providing Macintosh-based Internet access and Web hosting, Alan helped establish Open Door as a Macintosh Internet utilities company, focusing on AppleTalk-to-IP migration and Internet security. Alan and Open Door created such products as ShareWay IP (used by Apple to implement Mac OS 9's TCP/IP File Sharing), the DoorStop Personal Firewall (licensed by Symantec for use in their Norton Personal Firewall) and the Who's There? Firewall Advisor.
Alan lives in beautiful Ashland Oregon with his beautiful wife Priscilla and their cat Kingsford.
