Signature Movement Notes Griesbaum Founded in 1905 by Karl Griesbaum (1872-1941) in Triberg, in the Black Forest. The son of Mathias Griesbaum, a clockmaker, Karl began by working in the basement of his home. Karl Griesbaum had five children: Mathias (1902-1974), who was named after his grandfather, Karl Joseph (b. 1916), Amalia, Helena, and Caroline. Mathias studied clockmaking in Furtwangen, then pursued commercial studies in Karlsruhe, and later went to Switzerland. The most typical Griesbaum pieces produced during this period were probably their snuff boxes, particularly those made in a style reminiscent of traditional German silversmithery. The silver case of a comparable piece is known to have been crafted by Kurz & Co. of Hanau, a firm founded by Johann Sigmund Kurz (1818–1888). This esteemed silversmith is renowned for producing a variety of silver cases for musical boxes, famously creating designs in the shape of miniature pianos, books, animals and other novelty forms.
