Eugenio Barsanti

Italy (1821-1864)
Priest, Physicist, and Mathematician.

Eugenio Barsanti was born in 1821. After he’d gotten old enough to talk, walk, and make decisions about his own education, he joined the convent of Sant’ Agostino in Pretsanta to study at the  convent’s  scientific school. He obtained “higher studies with excellent results in all subjects, … [particularly]... scientific subjects,” (1) and went on to be ordained a priest.  After his novitiate, Fr. Barsanti decided to attend San Giovannino college. At some point, he was even a Professor of physics in the college of S. Giovannino.

He also taught physics and mathematics in Volterra at the college of San Michele. There, Fr. Barsanti developed a way “to use the bursting of air and gas to produce a new driving force.” He did this using “a reproduction of Alessandro Volta’s gun” which he built himself. He then filled it with hydrogen and air, and hermetically sealed it using a cork cap and a brass bar. The electrologopneumatic gun burst the seal, sending it flying toward the ceiling. This was a classroom demonstration.

After some time in Volterra, Fr. Barsanti continued “his experiments in physics at the Ximeniano Observatory in Florence … where he … had the opportunity to meet Felice Matteucci.” Felice Matteucci was also from Lucca, Italy and was working on reclamation of the Bientina lake. Barsanti was a physicist, Matteucci an engineer, and they worked well together.

The two worked together on creating an internal combustion engine. “Research and experiments [began in 1851]... with a cast-iron cylinder with a piston and valves, through which they studied the effects of some explosive mixtures.” (2) Once Barsanti and Matteucci created a prototype, they decided to patent their invention. “They applied for authorship in England, at the time the leading European country in the field of trade and industry.” (2) They also filed patents in 1853 in  France, Germany, and Italy.In 1854, they got their patent from England. They finished building the engine in 1860.  They also set up a company around the invention, an engine which featured a two-cylinder engine, twenty horsepower.  However, while the invention was brilliant in scientific terms and useful in economic ones (the force of a steam engine cost 12 cents, while their invention produced a force at 2 cents)(2), non-Italian countries initially stuck with a later, similar invention created by Etienne Lenoir and patented in 1859. In fact, for several decades no one discussed Barsanti and Matteucci’s invention at all, instead beginning the history of internal combustion engines with Lenoir’s invention.  (3)

Nonetheless, Matteucci and Fr. Barsanti continued their collaboration and created new prototypes of their engine. Then, in 1864, John Cockeril’s mining company in Belgium “decided to use [Father] Barsanti’s engine for a first series production, [as the new prototype was] much more efficient than Lenoir’s engine.” (1)

Fr. Barsanti’s life was filled with study, physical experimentation, and ecclesiastical duty.  He died at age 43, 1864 of typhoid fever, shortly before he was intended to participate “in the start of series construction of his engine” (1)
