Towards the end of March 1801, Jean-François left Figeac for Grenoble, which he reached on 27 March, and where Jacques-Joseph lived in a two-room flat on the rue Neuve. Jacques-Joseph was then working as an assistant in the import-export company Chatel, Champollion and Rif, yet taught his brother to read, and supported his education. His brother also may have been part of the source of Champollion's interest in Egypt, since as a young man he wanted to join Napoleon's Egyptian expedition, and often regretted not being able to go.
