Hamilton was born in Crow Street, in
Dublin,
Ireland, in 1740, the son of a
peruke maker. Unfortunately, there is very little concrete evidence of his early life, apart from his own drawings. He studied art under
Robert West and
James Mannin at the
Dublin Society House - and won some early success with crayon and pastel portraits there. He was very adept at building relationships with patrons from the early days, taking up with the famous La Touche banking family of Dublin, who had close ties with the
Bank of Ireland. Very little is known of Hamilton's career between 1756 and 1764, when he moved to
London. An album of drawings dated 1760 by Hamilton of Dublin street hawkers was rediscovered in Australia in 2002. Hamilton found great success in London through his
pastel oval portraits, portraying royalty, politicians and celebrities of the day through this medium. Hamilton was often overwhelmed with orders, including commissions from the British royal family - such as
Queen Charlotte (1764) and others now in the British Royal Collection. He showed with the Society of Artists and the Free Society of Artists from the mid-1760s to the mid-1770s. From the mid-1770s on, Hamilton became very interested in a softer, more textural form of pastel "fresco", in which he blended crayons and chalk to further the pastel's ability to imitate flesh. In 1779 he travelled to Italy, where he remained for the next twelve years, occasionally visiting
Florence but mainly based in
Rome, where he knew
Antonio Canova. On the advice of artist
John Flaxman Hamilton turned to oil painting, and achieved great success with small oval portraits of Irish and British visitors. His portraits of this period include those of
Dean Kirwan (displayed at the
Royal Dublin Society), George John, 2nd Earl Spencer, Countess Cowper (1787), and the exiled
Charles Edward Stuart (
Lord Edward, 1785). His portrait of Susan Frances Elizabeth (Anne) Butler (née Wandesford), Countess of Ormonde may be seen at
Kilkenny Castle. In 1791 Hamilton returned to Dublin, where he died. In 1796 he painted
Lord Edward Fitzgerald, the Irish revolutionary. One of his last portraits (c. 1804), of
William Downes, 1st Baron Downes,
Lord Chief Justice of Ireland, is considered to be one of his best. ==Style and technique==
