Lazzaro Spallanzanis Bladder

Italian biologist Lazzaro Spallanzani was best known in the 1700 as paving the scientific highways for Louis Pasteur by proving that microbes traveled by air and could be killed by boiling like most other living organisms! He also proved that sexual reproduction in mammals requires a sperm and an ovum, and performed the first successful artificial insemination on a dog. But his bladder was supposedly the most useful part to be preserved since he died from bladder cancer. Spallanzanis bladder remains on public display in a Pavia, Italy museum.,
