Riefler was founded by Clemens Riefler (1820-76) in 1841 following his apprenticeship with Ertel in Munich. The “Round System” of compasses, for which the firm is famous, was patented by his son Sigmund in 1877. The firm was located in Bavaria, with premises in Nesselwang and Munchen (Munich). Riefler continues today in Nesselwang, making drafting furniture and CAD equipment.
