Rabbi Samson ben Yosef the Elder of Falaise (Hebrew: רבי שמשון בן יוסף הזקן מפלייזא, romanized: Rabbi Shimshon ben Yosef Hazaken mi-Palaiza) was one of the Tosafot.[1] His brother-in-law was Rabbeinu Tam (his sister Miriam was married to Rabbeinu Tam), who held him in high esteem.[2]
He is mentioned in Tosafot in several places in the Talmud as someone who expressed an opinion or came up with a novel idea that was included due to its importance.[3]
^See Tosafot Yevamot 42a s.v. "stam," Tosafot Eruvin (Talmud) 32a s.v. "Rav" (although there he is mentioned as Rabbeinu Samson of Folirra, which is certainly Falaise, as cited in Or Zarua vol. 2 siman 240)
