British born, the Wadham brothers William Joseph and Alfred Sinclair were the sons of a notable deaf & dumb painter, Benjamin Brassett Wadham (1816-1904) who was himself the son of a notable artist.
(A third brother, Benjamin T, is also mentioned in the 1894 ‘Adelaide Observer’ report below as an artist, but he didn’t come to Australia).
W.J. had his first painting accepted by the Walker Art Gallery, Liverpool, aged 14. He migrated to Australia in 1885 – his brother followed in 1887. They had exhibitions in Melbourne in 1889 and 1895, which were well received. They settled in Adelaide, joining the South Australian Society of Arts.
They ran “Wadham & Sinclair’s Fine Art Institute” in Adelaide where they also gave lessons; travelling extensively, they were in New Zealand in 1896, Western Australia in 1897. Alfred returned to London in that year, and also in 1897 their works were well received at the London Exhibition of Dominion Art, attended by the Prince of Wales.
Joseph continued to travel, visiting & painting in South Africa and Canada as well as New Zealand and Australia. He helped found the Royal British Society of Artists which held their first exhibition in 1902. In latter years, he opened a commercial Art Gallery in Sydney, selling notable British artists including Birket Foster, Lord Leighton, Moreland, Wilkie, and the Pre-Raphaelite master, Sir John Millais.
He sold up the Gallery & moved back to England in 1923.
