#5 Brearli DID NOT work with STAINLESS steel. The word "stainless" was invented by Ernest Stewart, some years after Brearli patented his invention (BTW, his patent for AISI 420 (1913) was the second one, the first stainlesss steel was patented in 1912 by two engineers from Krupp Ironworks)/
Actually, Brearli was the first to start, but NOT the first to publish on the theme, and not the first to get patented.
#6 it's sad to upset you guys, but play-dough was patented in Germany in 1880 (as Plastiline), and in the UK (as Plasticine) in 1899. The Germans and the Brits used it for modelling from the very beginning.

#4 Is wrong. Sticky notes were invented by a musician who put rubber cement on some small paper to keep his place in a score.
