Stories from St Paul's: Sir Alexander Fleming

‘One sometimes finds what one is not looking for…’ Undoubtedly one of the greatest in a pantheon of great Scots is Sir Alexander Fleming, whose discovery of penicillin in 1928 revolutionised medicine, and has saved millions of lives. Today, a memorial plaque in the Crypt of St Paul’s marks the place where his ashes were laid to rest. Produced and presented by Douglas Anderson.
