The production of matches with white phosphorus in German-speaking countries started in 1833. Between 1839 and 1845 Lorinser saw nine cases of what he called "phosphorimus chronicus" in workers with white phosphorus, also known as yellow phosphorus, without proper safeguards. This disease, later called phosphorus necrosis of the jaw or "phossy jaw," was most commonly seen in workers in the match-stick industry in the 19th and early 20th century. Lorinser's long paper was the first published account of this disease.
