Braubach on the Rhine
Leitch exhibited at the Royal Academy of Arts in London between 1841 and 1861.After this he worked primarily in watercolour and exhibited mostly at the British Institution, the Society of British Artists, and the Royal Institute of Painters in Watercolour. He was vice-president of the latter for 20 years. Work by Leitch found in his studio after his death was sold at Christie's in March and April 1884. Leitch's style is often considered to be similar to the work of artist Clarkson Stanfield (1793 - 1867), who produced continental landscapes and architectural studies. Leitch's eldest son, Richard Principal Leitch (about 1827–1882), was also a landscape painter and he worked in a similar style to his father.
