Jean de Vivenzio , also known as Giovanni Vivenzio (174? - 1817), was a friend and pen pal of Giuseppe Piazzi. From a young age he distinguished himself in the fields of literature, science and especially medicine and soon became a lecturer at the University of Naples, as well as a famous scientist and writer. He taught surgery, obstetrics, anatomy and experimental physics. Additionally he was director of the hospital "Ospedale degli dei Reali ospedali Militari Incurabili e delle due Sicilie".
In 1780 de Vivenzio was appointed Knight of the Order of Constantine by King Ferdinand, as well as royal and court physician of the kingdom. He successfully lobbied the king to reopen the previously abolished military hospitals, which was realised in 1800. He was also a member of distinguished academies both in Italy and abroad (among them the National Academy of Medicine in Paris and the Russian Academy in St. Petersburg). Amongst other things Vivenzio published the "history of electricity and its medical application" in 1784, and a book on the history and theory of earthquakes in 1783.
In a letter addressed to the astronomer de Cesaris of Breat and dated October 1787, Cassella wrote that the "Sir Knight Vivenzio ... has had his valuable cabinet supplemented by a finely crafted tellurium and an unusual planetary system, which was carried out carefully by highly skilled British craftsmen. He is expecting a large Dollond telescope, a clock of the famous Arnold, a quadrant .... On the 16th of March, 1813 Federico Zuccari paid the sum of 800 ducats ... for a pendulum clock, four globes of Marchese Vivenzio as a purchase price for the Observatory of S. Gaudioso". After Vivenzio's death, his heirs sold his entire collection of scientific instruments.
