Please add credit to the two Jewish authors behind the Hebcal algorithms
The Hebcal UNIX program was a C reimplementation of the calendar code found in the Emacs text editor. That was written by Prof. Edward Reingold, who wrote a book on calendar algorithms with Nahum Dershowitz. I think it would be showing kavod to include both their names under the "About" page on Hebcal.org, as they are the ones who contributed the core technology. Here is a page with more information:

Thanks for the suggestion. We updated our "about Hebcal" page as follows
Hebcal was created in 1992 by Danny Sadinoff as a Unix/Linux program, derived in large part from the Emacs 19 calendar routines by Edward M. Reingold and Nachum Dershowitz.
