Jeremias Friedrich Gülich

Jeremias Friedrich Gülich 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.[2] He made contributions in improving the body of scientific knowledge on colour.[3] Johann Wolfgang von Goethe praised Jeremias' contribution to optics[4] heavily in his book Theory of Colours.[5] Although Jeremias and Goethe never conversed personally, Jeremias was very pleased to be praised by a figure so well known.[6] Jeremias also helped to set industry standards on dying, most notably of sheep wool.[3] 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]
