He took drawing lessons with Constant Vaucher but was essentially self-taught in the French Romantic tradition. He was considered the leader of the Geneva school and the most representative painter of the Reformation. He exhibited at the Salon in the Musée Rath, Geneva, as early as 1826 and subsequently at the Royal Academy, London (1839) and the Paris Salon (1831, 1840, 1841, 1843 and 1847). He was praised by the critics and Louis-Philippe and Ary Scheffer were among his admirers.
