KALAI, SAMUEL BEN JOSEPH (d. 1754), Karaite scholar of Chufut-Qaleh, Crimea. He was the head of the study-house in Chufut-Qaleh. After his demise Simḥah Isaac *Luzki occupied his place.
He wrote Me'il Shemu'el (which survived in several mss. in St. Petersburg, NY, Oxford, and Cambridge), a supercommentary on Sefer ha-Mivḥar by *Aaron b. Joseph; the work remained unfinished and was later edited by S.I. Luzki.
