He studied in his native town, Reggio Emilia, and obtained both his M.D. and Ph.D. (in a familiar Italian pattern) in 1688.
After 1689 he studied with (or perhaps worked with) Malpighi in Rome.
5. Religion
Affiliation: Catholic
6. Scientific Disciplines
Primary: Anatomy
Among Pacchioni's dissertations, from 1701 on, dealing with the structure and functions of the dura mater, the Dissertatio epistolaris de glandulis conglobatis durae meningis humanae (1705) is paticularly well known and contains his description of the arachnoidal, or so-called Pacchioni, granulations.
7. Means of Support
Primary: Medicine, Government
1689, attended the Santo Spirito hospital in Rome.
1690-3, assistant physician at the Ospedale della Consolazione.
1693-9, town doctor in Tivoli. (Note that this was a salaried position.)
In 1699 he moved to Rome and established a successful medical practice. Later he became head doctor at the Hospital of San Giovanni in Laterano and then at the Ospedale della Consolazione. He was also the physician to the Collegio Romano.
8. Patronage
Type: Scientist
It seems clear that Lancisi, who was ten years older and very well established in Rome, functioned as Pacchioni's mentor or patron. He is mentioned in connection with the move back from Tivoli and the appointments to the hospitals in Rome. Pacchioni dedicated De dura meningis fabrica, 1710, to Lancisi.
Pacchioni also dedicated Dissertatio epistolaris de glandulis, 1705, to the President of the Accademia de' Curiosi (the Italian sources give the name in Italian), of which Pacchioni was a member.
9. Technological Involvement
Type: Medical Practice
10. Scientific Societies
Memberships: Medical College, Institute Bologna, Academia Leopoldina
He was guided in anatomy by Malpighi when the latter lived in Rome from 1691 to 1694.
He collaborated with Lancisi on the explanatory text to Eustachi's Tabulae anatomicae (1714).
With Lancisi he corresponded with Morgagni.
Pacchioni was received into the Medical College of Reggio in 1697, even though he was then resident in Rome.
He was taken into the Academy of Bologna (the Institute) and into the Curiosi della natura (as the Italian sources' name for the Leopoldina).
