St Ives
Hepworth, Nicholson and their children went to live in Cornwall at the outbreak of the Second World War in 1939. She lived in Trewyn Studios in St Ives from 1949 until her death in 1975. Trewyn Studios had once been an outbuilding of Trewyn House, later purchased by her pupil and assistant John Milne in 1956. She said that "Finding Trewyn Studio was sort of magic. Here was a studio, a yard, and garden where I could work in open air and space." St Ives had become a refuge for many artists during the war. On 8 February 1949, Hepworth and Nicholson co-founded the Penwith Society of Arts at the Castle Inn; 19 artists were founding members, including Peter Lanyon and Bernard Leach.
Hepworth was also a skilled draughtsperson. After her daughter Sarah was hospitalised in 1944, she struck up a close friendship with the surgeon Norman Capener. At Capener's invitation, she was invited to view surgical procedures and, between 1947 and 1949, she produced nearly 80 drawings of operating rooms in chalk, ink, and pencil. Hepworth was fascinated by the similarities between surgeons and artists, stating: "There is, it seems to me, a close affinity between the work and approach of both physicians and surgeons, and painters and sculptors."
In 1950, works by Hepworth were exhibited in the British Pavilion at the XXV Venice Biennale alongside works by Matthew Smith and John Constable. The 1950 Biennale was the last time that contemporary British artists were exhibited alongside artists from the past. Two early public commissions, Contrapunctal Forms and Turning Forms, were exhibited at the Festival of Britain in 1951.
During this period, Hepworth and Nicholson divorced (1951). Hepworth moved away from working only in stone or wood and began to work with bronze and clay. Hepworth often used her garden in St Ives, which she designed with her friend the composer Priaulx Rainier, to view her large-scale bronzes.
Her eldest son Paul was killed on 13 February 1953 in a plane crash while serving with the Royal Air Force in Thailand. A memorial to him, Madonna and Child, is in the parish church of St Ives.
Exhausted, in part from her son's death, Hepworth travelled to Greece with her friend Margaret Gardiner in August 1954. They visited Athens, Delphi and many of the Aegean Islands.
When Hepworth returned to St Ives from Greece in August 1954 she found that Gardiner had sent her a large shipment of Nigerian guarea hardwood. Although she received only a single tree trunk, Hepworth noted that the shipment from Nigeria to the Tilbury docks came in at 17 tons. Between 1954 and 1956 Hepworth sculpted six pieces out of guarea wood, many of which were inspired by her trip to Greece, such as Corinthos (1954) and Curved Form (Delphi) (1955).
