# Who is Giuseppe Peano?

June 25, 2021Giuseppe Peano was an Italian mathematician, linguist and thinker who lived from 27 August 1858 to 20 April 1932. Giuseppe Peano is a scientist who has authored more than two hundred books and articles and is the founding father of mathematical logic and set theory.

Peano brought the mathematical system called Peano Axioms to the world of mathematics with his studies on natural numbers. As part of this effort, he made significant contributions to the development of the mathematical induction method.

Giuseppe Peano has spent most of his career teaching mathematics at the University of Turin. He was also the creator of an international auxiliary language called “Latino sine flexione” (non-inflected Latin), a simplified version of Classical Latin. Most of Peano’s books and writings were written in this version he created, and others in Italian.

Giuseppe Peano’s parents worked on a farm, and Giuseppe was born in this farmhouse called Tetto Galant, about 5 km from Cuneo. After attending the village school in Spinetta, she transferred to school in Cuneo and walked the 5km journey to school every day. His parents bought a house in Cuneo, but his father continued to work at Tetto Galant and his mother remained in Cuneo with Giuseppe and his other son.

Giuseppe’s mother had a brother who was a priest and lawyer in Turin, and when his uncle realized that Giuseppe was a very talented boy, he took him to Turin in 1870 to complete secondary education and prepare for university studies. Giuseppe took the exams at Ginnasio Cavour in 1873 and then entered the University of Turin after graduating from Liceo Cavour in 1876.

During Peano’s first year at the University of Turin, his teachers included D’Ovidio, who taught him analytical geometry and algebra. In his second year, he took mathematics from Angelo Genocchi and descriptive geometry from Giuseppe Bruno. Peano continued to study mathematics in his third year and found that he was the only student to do so. Others continued their studies at the School of Engineering that Peano originally planned to do. In his third year, Francesco Faà di Bruno taught him analysis and D’Ovidio taught him geometry. His final year teachers included D’Ovidio with a geometry course and Francesco Siacci with a mechanics course. On September 29, 1880, Peano graduated from this school as a doctor of mathematics.

Peano joined the staff of the University of Turin in 1880 as D’Ovidio’s assistant. Peano published his first paper in mathematics in 1880, and three more the following year. Peano was appointed as an assistant to another teacher, Genocchi, this time during 1881-82. Genocchi was quite old and relatively unhealthy by this time, and Peano took over some of his classes. When Peano realized that the definition in Serret’s book, which is the standard text of the lesson, was wrong, he immediately told Genocchi about this, and Genocchi said he already knew this. Genocchi disappointed Peano by explaining that Serret’s mistake had been previously identified by Schwarz.

Giuseppe Peano died on April 20, 1932, at the age of 73, in Turin, Italy.
