In the 1830s he became friends with artist Gustave Courbet and the two were close for the rest of Buchon's life.
Buchon was a follower of the French utopian socialist Charles Fourier but he could not convince Daguet that Fournier's ideas had validity.
[5] He was able to return home because his friend Gustave Courbet asked that Buchon be pardoned.
[2] He introduced the works of Swiss Novelist Jeremias Gotthelf to France by translating his writings.
He was interred in Salins cemetery and on his tomb there is a bust of Buchon which was created by Max Claudet.
