Computer History Museum Makes the Eudora Email Client Source Code Available to the Public

Early successful email client is released by Computer History Museum’s Center for Software History

Mountain View, May 22, 2018 (GLOBE NEWSWIRE) -- Computer History Museum (CHM), the world's leading institution exploring the history of computing and its impact on the human experience, today announced the public release and long-term preservation of the Eudora source code, one of the early successful email clients, as part of its Center for Software History’s Historical Source Code. The release comes after a five-year negotiation with Qualcomm.

The first version of Eudora was created in the 1980s by Steve Dorner who was working at the University of Illinois at Urbana-Champaign. It took Dorner over a year to create the first version of Eudora, which had 50,000 lines of C code and ran only on the Apple Macintosh.

In 1991, Qualcomm licensed Eudora from the University of Illinois and distributed it free of charge. Qualcomm later released Eudora as a consumer product in 1993, and it quickly gained popularity. Available both for the IBM PC and the Apple Macintosh, in its heyday Eudora had tens of millions of users.

After 15 years, in 2006, Qualcomm decided that Eudora was no longer consistent with their other major project lines, and they stopped development.

 “In my opinion it was the finest email client ever written, and it has yet to be surpassed. I still use it today, but, alas, the last version of Eudora was released in 2006,” said Len Shustek, chairman of the Museum’s Board of Trustees. “With thanks to Qualcomm, we are pleased to release the Eudora source code for its historical interest.”

The discussion with Qualcomm for the release of the Eudora source code by the company’s museum took five years. Qualcomm has transferred ownership of the code, the Eudora trademarks, copyrights, and the Eudora domain names to the Computer History Museum. The transfer agreement allows CHM to publish the code under the very liberal BSD open source license, which means that anyone can use it for either personal or commercial purposes.
