Jeremy James talks to Enid Lockhart.
Enid Lockhart began work in Paris in the early 1920s. She was the first woman guide in Europe, despite male opposition. She has worked continually for a well-known English tours company. Now 75, she is at this moment skin-diving in Malaya.
This week she describes how she began taking visitors to the First World War graves - and the champagne cellars.
