About Hilaire De Chardonnet
- Louis-Marie Hilaire Bernigaud de Grange, Count (Comte) de Chardonnet (1 May 1839 – 11 March 1924) was a French engineer and industrialist from Besançon, and inventor of artificial silk. In the late 1870s, Chardonnet was working with Louis Pasteur on a remedy to the epidemic that was destroying French silkworms.
- Failure to clean up a spill in the darkroom resulted in Chardonnet's discovery of nitrocellulose as a potential replacement for real silk.
- Realizing the value of such a discovery, Chardonnet began to develop his new product.He called his new invention "Chardonnet silk" (soie de Chardonnet) and displayed it in the Paris Exhibition of 1889.
- Unfortunately, Chardonnet's material was extremely flammable, and was subsequently replaced with other, more stable materials. He was the first to patent artificial silk, although Georges Audemars had invented a variety called rayon in 1855.
