Johan August Friderich Hoffmann
(1867 – 1934)
German by birth; worked for Emil Theodor Hjorth from c. 1893–1900. Established his own workshop in Copenhagen in 1900. His early instruments are rather German in character with a thin spirit-like varnish, but after around 1920 we see a thick oil-based varnish with a tendency to crackle.
