ProvenanceThe astronomer John Evershed FRS (1864-1956) commissioned this glass with the aid of a Royal Society grant from the Council Urgency Fund for the purpose of solar observation at his private observatory in Ewhurst, Surrey. The prism was transferred for use at the Royal Greenwich Observatory at Herstmonceaux Castle in 1953, then later returned to the Society.
