Charles Derosne

Louis-Charles Derosne (23 January 1780 – 21 September 1846) was a French chemist and an inventor of industrial manufacturing machinery who was actively involved in the French industrial revolution.

Derosne was born in Paris where his father François belonged to a family of apothecaries who ran the Cadet-Derosne pharmacy on Rue St. Honoré.

After the death of his father in 1796, the pharmacy was run by Charles's older brother Jean-François (1774–1855) who became famous for his analysis of opium in 1803.

Charles refined the opioid extract named narcotine and now known to be a mixture of several alkaloids including noscapine.

Charles was also involved in innovating techniques for refining sugar, distillation and in industrial manufacturing.
