"The German proliferation of knowledge created a curious situation that hardly anyone is likely to have noticed at the time. Sigismund Hermbstädt, for example, a chemistry and pharmacy professor in Berlin, who has long since disappeared into the oblivion of history, earned more royalties for his "Principles of Leather Tanning" published in 1806 than British author Mary Shelley did for her horror novel "Frankenstein," which is still famous today."

- zhdc1 5y agoLeather tanning is, apparently, a fairly complex subject (I have a pair of full-grain boots going on a decade plus of consistent wearing, and others that haven't lasted anywhere as close as long).
- bserge 5y agoYou are basically chemically altering the structure of a material. It's like treating steel - much harder than you'd think and yes, there are principles.
