This year's Sawyer Dialing Prize awarded at the 2011 NASS Conference in Seattle Washington was given to Helmut Sonderegger, "In recognition of his ongoing development and support of the dialing software Sonne, and his many years of leadership in his national society." His acceptance talk was on one of the first Copernican followers, Rheticus.
For many years Helmut Sonderegger has been active in the German Sundial Association and was chairman of a team of dialist to produce the 3rd Editiion of the Austrian Sundial Catalogue. His most famous free sundial software, „Sonne“ calculates about 20 different sundial types and his program „Alemma“ is devoted to the calculation of analemmatic sundials. The software is available at his website, www.helson.at. He endeavors to help people who make sundials through his software and through articles in the NASS Compendium and the German Rundschreiben, and for local groups.
Helmut was presented with a cash prize of $200 and a custom made Spectra Sundial by Jim Tallman of Artisan Industrials.
