I saw Fer de Vries for the first time 15 years ago at the inauguration of the sundial park in Genk (Flanders in Belgium), near my hometown. I could design, on the basis of his formulas for calculating flat sundials in all possible directions, a program that I have ever used and expanded to include the calculation of cylindrical sundials. After I used them for designing a cylindrical sundial in Brussels, he was willing to check the result and to approve it. http://www.wijzerweb.be/brussel001A.html I appreciated his concise, professional and accurate comments on the Sundial List. My thoughts go to his family and to his colleagues at the Sundial Association in the Netherlands.
