Jeremias Friedrich Gülich

Jeremias Friedrich Gülich (1733–1803^[2]) was a dyer in the neighbourhood of Stuttgart; he published the Complete Dyeing and Bleaching Book, an elaborate six-volume work on the technical details of dying.^[3] He made contributions in improving the body of scientific knowledge on colour.^[4] Johann Wolfgang von Goethe praised Jeremias' contribution to optics^[5] heavily in his book Theory of Colours.^[6] Although Jeremias and Goethe never conversed personally, Jeremias was very pleased to be praised by a figure so well known.^[7] Jeremias also helped to set industry standards on dying, most notably of sheep wool.^[4] After writing his books in Sindelfingen between the years 1776 and 1778, he ran a military orphanage in Ludwigsburg, where the boys spun cotton and the girls knitted and spun cotton and flax. In 1785, Jeremias opened his own cotton mill.^[1] By the end of his life he had become the sole supplier of clothing to the military and also opened a saltpeter and gunpowder factory.^[1]
