The Guardian :Marcel Proust on film: discovery of what could be the only existing footage – video
Canadian university professor Jean-Pierre Sirois-Trahan has found what is believed to be the first, and possibly only, footage of French writer Marcel Proust. Discovered in the Canadian National Cinema Centre archives, the black and white film is of a wedding cortège in 1904, and gives a brief glimpse of a man wearing a bowler hat and pearl-grey formal suit, descending a flight of stairs – believed to be Proust. No other footage is known to exist of the In Search of Lost Time author
