[8] James Stutt, an electrical engineer, worked at Tone Vale from 1931 to 1977, and devised an electroconvulsive therapy (ECT) machine with a control on it similar to the dial on a telephone.

[10] Somerset and England cricketer Harold Gimblett was admitted to Tone Vale with depression in 1953; he was treated with ECT.

[11] Following the arrival of psychiatrist Dr M F Bethell in the 1950s, Tone Vale and the Somerset Educational Authority cooperated in establishing Merrifield Children's Unit in the hospital's grounds.

Under the control of Dr Bethell and his chief nurse Donald Mackey, the unit allowed children and adolescents to be treated without the need to place them on a ward in the main hospital building.

[16] Many of the Tone Vale Hospital buildings have been demolished, but some have been preserved and incorporated into the new village of Cotford St Luke, which has developed since the late 1990s.
