The year Louis-Bernard Guyton-Morveau spent on the Committee of Public Instruction is rich in the numerous dossiers that he was asked to treat, as well as in the large variety of his activities. Successively or simultaneously, he was president of the committee, member of the section of weights and measures, of the commission in charge of the relations with the Committee of Public Safety (to which he remained very close as one of its former members), and as a participant in numerous temporary commissions. The arrival of the chemist in this committee enabled him to tackle as a specialist the process of aerostation; the reform of weights and measures, one of the priorities of the Nation ; the multiple issues concerning the reprocessing of papers and parchments accumulated during the Revolution ; the supervision of industry and inventions ; the sanitary regulations faced by the risk of epidemics—so many challenges he was confronted by as a scholar and a deputy.
