Jean Castaing was born in circa 1685 in France. Sorry but I don’t have any information about his early life or education. In circa 1679, he invented something (more on that in a moment). It took him several years but in 1686 his invention was approved by the Council of State for France.
His invention was so successful that a rival (George E. Ewing, Jr.) accused him of conspiracy along with two Paris Judges. He was found guilty in 1700, where he was imprisoned however he only served two years before being let out. His accuser was ordered to pay him $6,000.00 in damages (a hefty sum in those days) as well as three-fourths of the trial expenses. His history for what he did after his release is unknown, it is reported that he died in the early 18th century. No records of his death can be found.
What you may not know about Jean is that he invented the first machine capable of applying an edge lettering to coins that was before struck by hand using a mallet. The machine was capable of producing 20,000 coins each day. A truly remarkable way of mass producing back then.
