jan 2, 1863 - Yersinia Pestis is Pinned as Black Death Cause By Alexander Yersin

Description:

After noting that there were a lot of rats in China during the plague outbreak in the 1860's, Yersin not only made a connection between rats and plague but then used what would later be known as Koch's Postulates to discover the bacteria that causes the plague.
