Jaume Ferran i Clua

Jaume Ferran i Clua was a Spanish-French bacteriologist and sanitarian, contemporary of Robert Koch, and said by his fellows to have made some of the discoveries attributed to Koch. As early as 1885, he wrote on immunization against cholera. In 1893, his work on this subject was translated into French with the title L'Inoculation préventive contre le Cholera.
