The story of Conrad Martens begins in London in the early nineteenth century, when on 21 March 1801, a third son and fourth and youngest child was born to a merchant of German origins, J. Christopher Heinrich Martens, and his English wife, Rebecca née Turner. The family lived above their premises in the crowded old trading quarter of the city in a street called Crutched Friars, near the present day site of Fenchurch Street Station. ‘Having no taste for mercantile pursuits’, as Conrad Martens put it many years later, all three Martens boys became artists, despite the family's European traditions as merchants going back to the fifteenth century. Influenced by his older brothers, Conrad, at the age of sixteen, became a pupil of the well-known English landscape painter and teacher Anthony Van Dyke Copley Fielding.
