George Barret Sr. RA was an Irish landscape artist best known for his oil paintings, but also sometimes produced watercolours. He left Ireland in 1762 to move to London where he soon gained recognition as a leading artist of the period. He exhibited at the Society of Artists of Great Britain and was able to gain patronage from many leading art collectors. Barrett with other leading members left the Society in 1768 to found the Royal Academy, where he continued to exhibit until 1782.
Barrett appears to have travelled extensively in England including the Lake District and the Isle of Wight, Wales, and Scotland to undertake commissions for his patrons. He suffered from asthma and this caused him to move in 1772 to Westbourne Green, at the time a country village to the west of Paddington. While he earned considerable quantities of money from his paintings, he has been described as being ‘'feckless'’ with money.
He was helped in 1782 by Edmund Burke, with whom he had become friends when Burke attended Trinity College, Dublin. On Burke's recommendation he obtained the appointment of master painter of Chelsea Hospital, a post he held until his death in 1784.
