I think wanting to meet people who lived in past centuries rather fatuous.......BUT at the end of the 18th Century - before, during or after the Terror in the French Revolution - how I would have loved to know:
Le Prince de Liège, Talleyrand**, Mme. de la Tour du Pin.
**I was reminded of Duff Cooper's biography on reading his wife Diana's letters to their son [see blog entry of October 23, 2103]. I re-read this masterly book with the greatest pleasure.
