Lionel Hamilton-Renwick was born in Birling Manor, Northumberland on August 15th 1917 and died aged eighty-five. He was educated at Abbotsholme in Derbyshire. One day, Hamliton-Renwick was reading a sporting newspaper called Rally and he thought so little of the illustrations that he wrote to the editor, complaining that “my Jersey cows look more like horses than your illustrators' attempts”. The editor invited him to contribute a weekly illustration of a famous horse, which became his first commissions. He then returned to studies enrolling at Heatherley’s Art School for eighteen months in London, and later he studied under David Birch. Hamilton-Renwick had his first show at the Walkers Galleries in Bond Street, which was a huge success. He then decided to become a professional painter specialising in equestrian subjects. He would often sketch his subjects in the field and then would return to the studio to work them up in oils.
Hamilton-Renwick's art paralleled that of his personal life, as he actively bred animals. His family was involved with greyhounds, whippets, and border terriers for nearly a century beginning with his grandfather Sir George Renwick. For Hamilton-Renwick, growing up on his family estate in Newminster Abbey, he was surrounded by racehorses and pedigree stock which naturally sparked his interest in breeding. As a breeder, Hamilton-Renwick produced prize-winning Siamese cats; Jersey cows; poultry; and miniature Shetland and Spotted ponies. However, dogs were his real forte. He became a fixture at Crufts, not only winning the Best in Show ring on eleven occasions, but also judging the shows many times.
He was commissioned by a range of wealthy and even royal patrons. He painted the Queens racehorse Aureole (winner of the 1954 King George VI and Queen Elizabeth Diamond stakes) that now hangs in Buckingham Palace. The Queen mother also used one of Hamilton-Renwick's mare and foal paintings for her Christmas card.
