Judah Messer Leon
Italian philosopher, rabbi and physician
Judah ben Jehiel, (Hebrew: יהודה בן יחיאל, c. 1420 to 1425 – c. 1498), more usually called Judah Messer Leon (Hebrew: יהודה מסר לאון), was an Italian rabbi, teacher, physician, and philosopher. Through his works, assimilating and embodying the intellectual approach of the best Italian universities of the time, yet setting it inside the intellectual culture of Jewish tradition, he is seen as a quintessential example of a hakham kolel ("comprehensive scholar"), a scholar who excelled in both secular and rabbinic studies, the Hebrew equivalent of a Renaissance man. This was the ideal he tried to instil in his students. One of his students was Yohanan Alemanno.
Life
Judah is thought to have been born in around 1420 at Montecchio Maggiore, now in the Italian province of Vicenza. The son of a doctor, he was ordained as a rabbi and received a diploma in medicine while in his early 20s. According to tradition the honorific title Messer (a title of knighthood) was bestowed on him by the Frederick III, Holy Roman Emperor, during the emperor's first visit to Italy in 1452, perhaps for work for him as a physician. The name "Leon" is the usual equivalent of "Judah", through the traditional identification of the lion of Judah.

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
