I have a book on the exploits of German born Katterfelto. He was fascinating as he walked a tightrope between real science and hokum. He was arrested once for setting fire to a hayrick when his balloon came down in a field. In his hey day his arrival was announced in town by a pair of young African boys in livery blowing trumpets, but he and his family died in poverty. This is one of his ads. I wish I knew what half the things he names refer to, though a few are hard to read. This is from the Birmingham Gazette of 1776:
“To the Curious and the Public in General
A son of col. Katterfelto from the famous Regiment, the Death Head Hussars, belonging tot he King of PRUSSIA, has traveled now these 15 years, through all parts of Europe and spent a considerable Fortune to Improve himself in Philosophy and Mathematics.
