Johann Sühl lived in Delft all his life and made paintings, etchings and engravings of landscapes, animals and farms. He often spent the summer months in North Brabant, Gelderland and Limburg and, following the example of other Delft painters, he started working as a pottery painter at 'De Porseleyne Fles' in 1920. He learned the painting trade from his older brother G.B.M. Sühl (1857-1926) and during an evening course at the Academy of Fine Arts in The Hague.
