A photograph of two technicians working on tisue samples, taken by an unknown photographer for the Daily Herald newspaper in 1962. New drugs need testing to make sure they are safe to use. These two technicians are working in the drug testing laboratory at Pfizer Inc, Sandwich, Kent. Susan Dack, in the foreground is preparing tisue sections ready for mounting and staining. In the background her colleague Margaret Penny is loading samples into an automatic tisue procesor. This photograph has been selected from the Daily Herald Archive, a collection of over three million photographs. The archive holds work of international, national and local importance by both staff and agency photographers.
