William Daniell RA (1769–1837) was an English landscape and marine painter, and printmaker, notable for his work in aquatint. He travelled extensively in India in the company of his uncle Thomas Daniell, with whom he collaborated on one of the finest illustrated works of the period – Oriental Scenery. He later travelled around the coastline of Britain to paint watercolours for the equally ambitious book A Voyage Round Great Britain. His work was exhibited at the Royal Academy and the British Institution and he became a Royal Academician in 1822.
William Daniell was born in Kingston upon Thames, Surrey. His father was a bricklayer and owner of a public house called The Swan in nearby Chertsey. Daniell's future was dramatically changed when he was sent to live with his uncle, the landscape artist Thomas Daniell (1749–1840) after his father's premature death in 1779. In 1784 William accompanied his uncle to India, who worked there on a series of prints, acting as his assistant in preparing drawings and sketches. William's brother Samuel Daniell remained independent of his uncle and also became a topographical artist; he went to South Africa in 1801 and after his return to England published African Scenery and Animals (1804–5), a collection of aquatints. From 1806 he lived in Ceylon.
Daniell was sixteen when he accompanied his uncle to India. On 17 July 1786, a few months after their arrival in Calcutta, Thomas Daniell placed an advertisement in the Calcutta Chronicle, announcing the forthcoming publication of a set of twelve views of the city. This seemed a promising idea, since Calcutta was rapidly expanding and its European inhabitants might be willing to buy prints showing its latest buildings. Both he and William were inexperienced printmakers and had to enlist the help of Indian craftsmen, but the set, executed in aquatint, was completed in November 1788 and sold well. Thomas then began planning an ambitious tour of northern India, possibly inspired by the wealth of picturesque scenery indicated in William Hodges's collection of aquatints, Select Views in India (1785–8). In August 1789, Thomas and William set off up-river past Murshidabad to Bhagalpur, where they stayed with Samuel Davis (1760–1819), an employee of the East India Company and a skilled amateur artist. They continued on to Kanpur and then travelled overland to Delhi, visiting Agra, Fatehpur Sikri and Mathura on the way; the following April they made a pioneering tour to Srinagar, Uttarakhand and Garhwal in the Himalayas.
