Rabbi Jonah Teomim-Frankel, sometimes written as Jonah Teomim Frankel (1595-1669) was author of the book Kikayon deYona. The word "tə'omim" (תְּאוֹמִים) means "twins".
He was the son of Reb Yeshia Teumim.[1] He led various communities as both a Posek and Rosh Yeshiva throughout Poland and Lithuania.
He served the Jewish community of Metz, France.[2]
He died on the 15th of Nissan,[3] and was buried in the famous Jewish cemetery of Metz. His grandson was Rabbi Baruch Fränkel-Teomim.
He is best known for authoring Kikayon DeYona, a commentary on the Talmud, Rashi, Tosfos, Maharshal, and Maharsha to various tractates. The commentary was recently re-printed in 1958 in Mount Kisco, New York by the Nitra yeshiva (formerly from Slovakia before the Holocaust) with footnotes and glosses by Rabbi Chaim Michael Dov Weissmandl.
