Paternal family home, 60 rue Pasteur.
Louis Pasteur’s father, Jean-Joseph,born March 16, 1791 lost his parents when he was young. He was taken charge of by his grand- mother at Salins. Later on, his father’s sisters, once married to a wood merchant, adopted the orphan. He was carefully brought up, but without much learning. Besides, Jean Joseph had to earn his living at the tanner’s trade, which had been his father’s and his grand-father’s before him. Jean Joseph was drawn as a conscript in 1811, and went through the Peninsular War in 1812 and 1813.
