Margaret Lindsey Williams, 1888-1960, is more famous for her portrait works, which is perhaps why this group-scene had slipped out of memory.
Growing up in Barry, Vale of Glamorgan, she studied at the Cardiff Technical College where she won a gold medal.
She later attended Pelham School of Art, Kensington, and then the Royal Academy of Arts, where in 1906, she studied under the renowned portraitist John Singer Sargeant.
Williams was famed for her raucous and fun-filled parties with fellow artists and socialites, in her St John’s Wood home during the early 20th century.
She is best known as portraitist by royal appointment – painting Queen Elizabeth II on five occasions, and also Princess Anne and a very young King Charles, who is said to have turned up for his sitting wearing overalls and carrying paint brushes, as Williams had inspired him to become an artist too.
She ventured to the States, where she painted car pioneer Henry Ford, and President Warren Harding, who posed for her in the Oval Office.
