How was synthetic rubber invented?

In 1860, Greville Williams obtained a liquid with the same formula by distilling rubber; he called it “isoprene.” Synthetic rubber technology started in 1879, when Gustave Bouchardat found that heating isoprene with hydrochloric acid produced a rubberlike polymer.

Is rubber toxic to humans?
