During the traditional annual summer lunch of all  the staff members there was a unique moment when Mr Henk Visser (1929), who was the designer of Deno from 1948 to 1964, met his grandson Simon Visser(1989), who just completed his apprenticeship as a mechanical engineer in our company. Another special guest was  Mrs van Duyvendijk(1922), the daughter-in-law of one of the founders of Deno Compressors.
