Who is Francesco Redi and what did he do?

Francesco Redi (born February 18, 1626 in Arezzo, Italy—died March 1, 1697 in Pisa), an Italian physician and poet who established that the appearance of maggots in putrefying meat is caused by flies' eggs deposited on the flesh rather than by spontaneous growth. His work On the Generation of Insects (1665) was the first treatise on entomology.

Redi was born into a wealthy family of physicians; his father had also been a professor at the University of Padua. When Redi was still a young man, his father died, leaving him a large fortune. Redi then studied medicine at the universities of Pavia and Padua, receiving his license to practice in 1649. That same year, he began publishing essays on medical topics, which were well received by scholars and readers alike. In 1665, Redi published his most important work, On the Generation of Insects, which introduced many novel ideas about insect biology. The book was widely read and influenced many later writers on entomology.

In addition to being a scholar, Redi was also interested in poetry and music. He wrote several books on these subjects as well. One of his poems was even set to music by Vivaldi.

Redi was married three times. His first two marriages ended in divorce.

When did Francesco Redi discover cells?

In 1668, an Italian physician called Francesco Redi proposed a theory to dispute the concept of spontaneous generation—specifically, the assumption that maggots might be born from flesh. He subsequently came to the conclusion that maggots form only when flies come into touch with flesh, and that spontaneous production does not occur. In other words, he proved that life cannot be generated from non-living matter.

Two years later, in 1670, Redi published his findings on this issue. The next year, he went further by publishing one of the first descriptions of a cell. He suggested that cells come in two different types: solid particles for bone tissue and liquid particles for blood cells.

Three years after that discovery, French scientist René Descartes put forward his own version of cellular theory. He too believed that everything is made up of simple components called atoms. These atoms are the basic building blocks of everything in the universe. They can combine together to form larger molecules such as sugars or proteins. But atoms cannot generate energy themselves; they only exist within certain objects which emit electrons to fill their empty nuclei (the nucleus of an atom is where most of its mass is located). This is why everything found in nature must either be created by God or else it cannot exist. Since atoms cannot create life, they must have been created by someone who knows how to create life. This means that God must exist.

What did Francesco Redi put in his glass jars?

Francesco Redi put fresh meat in open containers [left] to test the concept; as predicted, the decaying flesh attracted flies, and the meat quickly became swarmed with maggots, which hatched into flies. No maggots were formed when the jars were covered such that flies could not get into the centre. This experiment proved that worms are essential for decomposition.

In addition to these experiments, Redi also wrote books on human anatomy and medicine, including A Treatise on Galenism (1615), which contained over 300 drawings of organs removed from dead bodies. His works included many anecdotes about animals. For example, he wrote that if a cat will not eat anything for several days then it is time to kill it.

Redi also conducted some very interesting experiments regarding the existence of evil. For example, he put roast pig's feet in a dish where they could be seen by anyone who visited his house, but no one ever refused to eat them. He concluded that there must be something wrong with the feet - perhaps they had been bought from a butcher who sold spoiled meat? - so he decided to try another experiment: he would bury the feet in the ground beneath a tree at his home. Sure enough, the bones soon began to rot and fall apart. This proved that there was nothing wrong with the feet; instead, it was evident that someone had taken pleasure in ruining them.
