Concentrating ethanol through repeated fractional distillation using a water-cooled still allowed Taddeo Alderotti to reach a purity level of 90 percent. This advancement stands as a hallmark of his technical contributions during the High Middle Ages, bridging the gap between ancient theoretical texts and practical scientific application in thirteenth-century Europe.
Academic Career at Bologna
Born in Florence in 1215, Alderotti migrated to Bologna in the mid-1260s. During this era, Bologna held a dominant position in European medical education alongside Montpellier and Paris. As a professor at the University of Bologna, he structured medical lectures based on authoritative texts from Hippocrates, Galen, and Avicenna. His teaching methods attracted substantial student audiences, many of whom later became influential figures, including Mondino de' Liuzzi, Gentile da Cingoli, and Bartolomeo da Varignana.

Beyond his academic duties, Alderotti maintained a busy medical practice. He treated patients across Italy, with clients residing in cities such as Modena, Ferrara, Milan, and Rome. His methodology focused on clinical application rather than purely theoretical discourse. In his later years, he transitioned from teaching to private practice in Venice. His personal wealth, documented in his last will and testament, reflected the significant financial success achieved through his clinical work, academic investments, and teaching career.
Literary and Scientific Output
Alderotti authored several significant texts that codified medical knowledge, including Consilia medicinalia, Expositiones, and In Claudii Galeni artem parvam commentarii. He also wrote Libellus conservande sanitatis and Etica in volgare. These works, composed in medieval Latin and medieval Italian, synthesized knowledge preserved by Islamic scholars. His writings provided a foundation for the subsequent generation of practitioners, and his intellectual reach was broad enough to warrant a mention by Dante in Paradiso.
