apart from the acid, has he discovered anything else?
Codeine is one of his other discoveries
Pierre Jean Robiquet
Codeine is probably Robiquet's most important contribution, that prevails still today with a very strong presence and impact on daily life; in effect, until the beginning of the 19th century, raw opium was used in diverse preparations known as laudanum (see Thomas de Quincey's "Confessions of an English Opium-Eater"), paregoric elixirs (a number of them, very popular in England since the beginning of the 18th century), and health or even death hazards to users from improper preparation or improper use were frequent.

Pierre Jean Robiquet [SEP] Discovery and industrialization of codeine
Codeine is probably Robiquet's most important contribution, that prevails still today with a very strong presence and impact on daily life; in effect, until the beginning of the 19th century, raw opium was used in diverse preparations known as laudanum (see Thomas de Quincey's "Confessions of an English Opium-Eater"), paregoric elixirs (a number of them, very popular in England since the beginning of the 18th century), and health or even death hazards to users from improper preparation or improper use were frequent. The isolation of codeine by Robiquet from opium's several active components while working on refined morphine extraction processes, opened the path to the elaboration of a new generation of specific antitussive and antidiarrheal potions of much safer use, based on codeine only, which became immediately extremely popular.
