The video below comes, perhaps, from this schedule, from the Radio Times, Thursday 22nd October 1937, where Charlotte Wolff presented 'The Hands of Chimpanzees’, with Alan Best (who, it seemed, worked with Julian Huxley and was a curator at the Zoo), part of the Experiments in Science series. Chimpanzees lent by the London Zoological Society.
Others programmes in the series include:
7 October 1937 | Professor Mary Waller will show some of the unique properties of solid carbon dioxide
4 November 1937 | Cyril Burt, D.Sc , Professor of Psychology, University College, London, demonstrates the tests which have been devised to estimate intelligence and vocational aptitudes
16 December 1937 | Reconstructing the Past. A demonstration conducted by Margot Eates, of the Institute of Archaeology
Images of these Chimpanzees’ hands appear as prints throughout Wolff’s work.
