Giovanni Sartori was an Italian researcher in the field of political science, specializing in the comparative study of politics. His work is one of the most outstanding in the social sciences. He was born on May 13, 1924, in Florence, Italy. As of 1946, he studied for a degree in Social Sciences at the University of Florence, and three doctorates, namely: in Political Science, in History of Modern Philosophy, 1954, and State Theory, 1955. From then on was He dedicated himself to contribute deeply in the field of political science not only in Italy but throughout the world. He passed away on April 4, 2017, in Rome, at the age of 92. Sartori contributed to the development of different aspects of political science, such as democratic theory, party systems, or comparative constitutional engineering. His works have also served to clarify various concepts and methods of this social science. This is reflected in works such as "Democrazia e Definizioni", "Stato e Politica nel Pensiero di Benedetto Croce" or "Political Development and Political Engineering". I like this author in particular because his critical ideas about the presidential model in Latin America seem very interesting to me. For this, I have quoted this author many times in my research papers on this particular topic.
