Featured Update: Roger Summit, founder of Dialog Information Services (aka Dialog), paved the way for automated, interactive information retrieval that defined online searching some 25 years before Google existed. In his mid-90s and still in good health, Summit was hit by a car at The Forum, a retirement community in Cupertino, California, where he lived, and taken to Stanford Hospital. He did not survive the accident.
The members of the DIALOG-X (former employees) mailing list have received information that Roger Summit has passed. The details are minimal at this point, it occurred Saturday, June 6, 2026. We will post more information as it becomes known and published.
Here’s Roger’s Wikipedia page, and he’s of course featured here in the Web site, we built to honor him, and keep the history alive.
