John Casson: A Famous Inventor!

When we were in the Museum of the History of Science last week, we came across this exhibit. A certain John Casson (my dad’s namesake), invented an early type of braille (panagrams) way back in the early 1800s. The little letter cubes are really beautiful; pity they didn’t catch on. The rest of this wonderful museum is packed full of strange and wonderful first generation scientific instruments – astrolabes, microscopes, various electronic communicators, models of the universe. There were also all sorts of different types of clocks and time keepers. Max, Grace, and Claire built Japanese fire clocks.  -Doug
