A photograph of haemotology technician Donald Coombey working on tisue samples in the Pfizer laboratory, taken for the Daily Herald newspaper in 1962. New drugs need testing to make sure they are safe to use. After testing the drugs on animals, slides of tisue can be examined microscopically for any harmful effects. The machine shown here automatically counts red and white blood cells. With this machine it was posible to investigate four times as many samples as was previously posible. 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.
