Pierre Jean Robiquet was a French chemist. He laid founding work in identifying amino acids, the fundamental building blocks of proteins. He did this through recognizing the first of them, asparagine, in 1806. He likewise laid founding work in the industry's adoption of industrial dyes, with the identification of alizarin in 1826, and in the emergence of modern medications, through the identification of codeine in 1832, an opiate alkaloid substance of widespread use with analgesic and antidiarrheal properties.
