Ernst Felix Immanuel Hoppe-Seyler (né Felix Hoppe; 26 December 1825 – 10 August 1895) was a German physiologist and chemist, and the principal founder of the disciplines of biochemistry and molecular biology. He had discovered Yeast nucleic acid which is now called RNA in his attempts to follow up and confirm Miescher's results by repeating parts of Miescher's experiments. He took the name Hoppe-Seyler when he was adopted by his brother-in-law, a grandson of the famous theatre principal Abel Seyler. Source: Wikipedia (en)
