Johann Joachim Becher: Foolish Wisdom and Wise Folly: Or One Hundred Concepts and Propositions, Political and Physical, Mechanical and Mercantile, Some of Which Have Been Useful, Others Useless […] 1707
GF has been producing malleable cast iron fittings for over 150 years. Johann Conrad Fischer had earlier experimented with this material and was granted a patent for it in Austria in 1828. A new acquisition shows that working with malleable cast iron goes back even further in time. In 1670 Prince Rupert had his technique patented in England – a real prince!
This book – our copy is from 1707 – was written by Johann Joachim Becher, a flamboyant all-rounder. The title, somewhat unusual for today's readers, is "Foolish Wisdom and Wise Folly". The book first appeared in 1682 and was reprinted eight times. Gerhard Dünnhaupt remarks about this book: "A collection of curious ideas and inventions, plus alchemical, physical and medical experiments and formulae conceived during a stormy, 28-day sea voyage to Scotland."
