Serafino Serrati

Serafino Serrati (18th-century) was an Italian Benedictine monk, who also practiced or taught physical sciences. He appears to have lived in the Badia Fiorentina (Florentine Abbey of monks of the order of Monte Cassino). He is now best remembered because the bacterial genus for a specific gram-negative rod-shaped bacteria called Serratia is named after him in 1819 by the botanist and chemist Bartolomeo Bizio (1791 – 1862) to honor him for his unrecognized invention of a steamboat.

Biography

Information regarding Serafino is limited. Born in the 18th-century in Florence to a respectable family, he appears to have studied physics and botany. He is thought to have been the professor of experimental physics in his monastery.

Among his preferred studies was to find ways to direct the movement of globi areostatici, today in English referred to as hot-air balloons. It is said that his fellow monk Rabatta and Serrati were the first Florentines to become air-bound by globes. In addition, according to a biographer he was the first to apply the force of vapor from lumber to move in water ^[1] An article by Jouffroy d'Ambrans reported on his barchetto a fuoco (ship on fire).

He was said to have been adept and diligent in his monastic responsibility. One anecdote is that once upon hearing the bells calling the monks to choir as part of the liturgy of the hours, Serrafino would rush over still wearing the apron he was using while at work at some chemical oven. The editor of his letters remarks on his modesty and humility, and dismissal of world fame. ^[2]

Among his reports published in life are the following nine communications: ^[3]

• Regarding observations in the choice of flammable air
• Describing a two-burner retort to decompose wine spirit into flammable air
• Which describes a model to form an aerostatic globe with a conical shape, without making seams that lose the air that is introduced into it
• What explains the direction of a balloon for any part, and at any height
• Representation of a flush scale, without friction
• About a pneumatic machine powered by mercury
• Description of a positive and negative conductor of an electrophore without resins
• Description of a boat powered by fire, who with that force, moves without wind(power)
• Describing a reverberating oven, for the use of baking bread.

Observations

The obscurity of the scientific efforts of Serafino recall the obscurity of Gregor Mendel's observations in the next century. However, Serafino could be considered only be one addition to a long list of Catholic clergy scientists.
