Photo of a man born in 1746

Looking through my old photos I found this today. This appeared in a newspaper some years ago and it shows a man who was 102yrs old when the photo was taken in 1848. This means he was born in 1746, 10 years before Mozart was born and was a middle aged man when the Bastille was stormed in Paris. The calotype photo was taken by William Collie who I believe was a photographer on Jersey in the Channel Islands. See also http://www.all-art.org/history658_photography5-2.html
