Francesco Redi

Francesco Redi (* 18-19 February 1626 in Arezzo, . † 1 March 1697 in Pisa ) was an Italian physician.

He was known for his experiment in 1668, the ( spontanea generations, spontaneous generation ) is an important step in the refutation of abiogenesis was. At that time it was believed that maggots arise of itself in rotting meat. In his experiment, Redi took three pots and filled them with meat. He completed a pot completely. The second pot he left open and the third pot he covered with gauze. Maggots appeared only in the open, but not in the sealed pot. On the gauze of the third pot he found ( developing ) maggots.

He continued his experiments, he captured by maggots, waiting until they further developed. This they did and were ordinary flies. If you were dead flies or maggots in meat sealed pots, there was no new maggots. But if you did that with living flies, maggots appeared in meat. Thus the theory of abiogenesis was refuted.

Then, Redi formulated the famous phrase: Omne ex ovo vivum. ( " All life comes from an egg. " )

Redi was also a poet. His most famous work is Bacco in Toscana.
