Shlomo Ganzfried (or Salomon ben Joseph Ganzfried; 1804 in Ungvar – 30 July 1886 in Ungvar) was an Orthodox rabbi and posek best known as the author of the work of Halakha (Jewish law), the Kitzur Shulchan Aruch (Hebrew? ?, "The Abbreviated Shulchan Aruch"), by which title he is also known.
Ganzfried was born in 1804 in Ungvar, in the Ung County of the Kingdom of Hungary (present-day Ukraine). His father Joseph died when he was eight. Ganzfried was considered to be a child prodigy and Ungvar's chief rabbi and Rosh yeshiva, Rabbi Zvi Hirsh Heller assumed legal guardianship; Heller was known as "Hershele the Sharp-witted" for his piercing insights into the Talmud. Heller later moved to the city of Bonyhád, and Ganzfried, then fifteen, followed him. He remained in Heller's yeshiva for almost a decade until his ordination and marriage. After his marriage he worked briefly as a wine merchant.
In 1830, he abandoned commerce and accepted the position of Rabbi of Brezovica (Brezevitz). In 1849, he returned to Ungvar as a dayan, a judge in the religious court. At that time Ungvar's spiritual head, Rabbi Meir Ash, was active in the Orthodox camp, in opposition to the Neologs. Through serving with Ash, Ganzfried realised that in order to remain committed to Orthodoxy, "the average Jew required an underpinning of a knowledge of practical halakha (Jewish law)". It was to this end that Ganzfried composed the Kitzur Shulchan Aruch. This work became very popular, and was frequently reprinted in Hebrew and in Yiddish. This work often records more stringent positions.
Rabbi Ganzfried remained in the office of Dayan until his death on July 30, 1886.
The Kitzur Shulchan Aruch, first published in 1864, is a summary of the Shulchan Aruch of Joseph Karo with reference to later commentaries. This work was explicitly written as a popular text, in simple Hebrew, and does not have the same level of detail as the Shulchan Aruch itself.
