Henri Jannin (January 4, 1816 - 18xx) was a French lithographer and printer. Born in Lyon, Jannin opened his own printing firm in 1839. In 1841 he as put on trial for not printing his name and address on his products, and also for printing socialist propaganda lithographs. He was fined 6,000 francs in May 1850, but it was reduced to 1,000 in November. In 1864 and again in 1867, two major commissions were created by Jannin and then printed by another firm, suggesting that Jannin may have gotten out of the printing business sometime in the early 1860s.
