In July 1929, Moore married Irina Radetsky, a painting student at the Royal College.
Irina found security in her marriage to Moore and was soon posing for him. Shortly after they married, the couple moved to a studio in Hampstead at 11a Parkhill Road NW3, joining a small colony of avant-garde artists who were taking root there.
After their Hampstead home was hit by bomb shrapnel in September 1940, Moore and Irina moved out of London to live in a farmhouse called Hoglands in the hamlet of Perry Green near Much Hadham, Hertfordshire.
After the war and following several earlier miscarriages, Irina gave birth to their daughter, Mary Moore, in March 1946. The child was named after Moore's mother, who had died two years earlier. Both the loss of his mother and the arrival of a baby focused Moore's mind on the family, which he expressed in his work by producing many "mother-and-child" compositions, although reclining and internal/external figures also remained popular.
By 1977, he was paying close to a million pounds a year in income tax; to mitigate his tax burden, he established the Henry Moore Foundation as a registered charity with Irina and Mary as trustees.
