[1] Duiffopruggar is believed to have been born near Füssen in Bavaria, Germany, and had moved to Lyon, France, where he did most of his work, by 1553.

[2] Duiffopruggar instruments are rare and tend to be of the viol family.

The best examples come from the workshop of the Parisian violin-maker, Jean-Baptiste Vuillaume.

They were made for Vuillaume by Honoré Derazey (1794–1883) and sold to the public to supply the demand for older instruments.
