The Institut Pasteur was opened on November 14, 1888 thanks to Louis Pasteur’s international appeal for funds. He now had the facilities to extend vaccination against rabies, continue research on infectious diseases and share the resulting knowledge.



"My dear colleagues, maintain the enthusiasm that you showed right from the beginning. At the same time, keep constant vigilance over monitoring operations. Never advance anything that cannot be proved in a simple and decisive manner. Adopt a critical mind. By itself, it can neither encourage ideas nor stimulate anything great. But without it, everything is useless. It always has the last word. "*
