The work for which I seem to be best known is:

• Grapevine (1981, distributed email, with the first distributed naming system);
• Implementing Remote Procedure Calls (1983);
• Programming with Threads (1989, still required reading in many CS courses);
• Pachyderm (1996, index-based email “in the cloud” with a web-based client);
• the Personal Jukebox (1998, the first multi-gigabyte portable audio player).
