Samson ben Samson of Coucy (Hebrew: שמשון בן שמשון מקוצי), known as the Count (or Prince) of Coucy (Hebrew: השר מקוצי), was a French rabbi and Tosafist who flourished at the end of the twelfth and in the first half of the thirteenth century.
These legends were popularised by writers such as Marcus Lehmann and Micha Josef Berdyczewski.
[3] However the simple origin of this title is due to the acronym of his name in Hebrew, HaRaSH (HaRav Rabbenu SHimshon), which was subsequently converted into its anagram, HaSar (Hebrew: השר), meaning the Count, or Prince.
[1] Many of Samson's halakhic decisions are mentioned in the rabbinical works Tosafot, Or Zarua, Sefer Mitzvot Gadol, Orḥot Ḥayyim, and Pisḳe Reḳanati.
