Simhah ben Samuel of Vitry

Simhah ben Samuel of Vitry (Hebrew: שמחה בן שמואל מויטרי‬; died 1105) was a French Talmudist of the 11th and 12th centuries, pupil of Rashi, and the compiler of the Vitry Machzor.

The Vitry Machzor contains decisions and rules concerning religious practise, besides responsa by Rashi and other authorities, both contemporary and earlier. The work is cited as early as the 12th century in R. Jacob Tam's Sefer ha-Yashar (No. 620) as having been compiled by Simchah; and the sources from which the compiler took his material—the Seder Rav Amram, the Halakot Gedolot, and others—also are mentioned. R. Isaac the Elder, a grandson of Simchah, also refers (responsum No. 835, in Mordekai, on Mo'ed Katan) to the Vitry Machzor compiled by his grandfather. Various additions were afterward made to this machzor, a large proportion of which, designated by the letter ת'‬ (= "tosafot"), are by R. Isaac ben Dorbolo (Durbal). The latter often appends his name to such additions; and in one place he says plainly: "These explanations were added by me, Isaac b. Dorbolo; but the following is from the Machzor of R. Simchah of Vitry himself". Other additions are by Abraham ben Nathan Yarhi, author of Ha-Manhig, and are designated by the letters אב"ן‬, his initials.
