Eric Leighton Holmes

Eric Leighton Holmes (4 July 1902 – 20 November 1966) was a British chemist who developed ion exchange resins in 1935, while working for the British Department of Scientific and Industrial Research.

Holmes was born in Hornsea, East Yorkshire.

He was a 1951 recipient of the Franklin Institute's Howard N. Potts Medal in Chemistry with his co-researcher Basil A. Adams being awarded the Engineering medal for that year. Holmes also received the 1958 John Scott Medal from the City Council of Philadelphia for the same work, with this medal awarded to those whose work has improved the "comfort, welfare, and happiness of human kind". These were both awards made by US institutions, and the author of Holmes's 1967 obituary in the Effluent & Water Treatment Journal expressed regret that he was "not similarly honoured by Britain".
