Early life

Aryeh Kaplan was born in the Bronx, New York City to Samuel^[1] and Fannie^[2] (Lackman) Kaplan^[9][10] of the Sefardi Recanati family from Salonika, Greece.^[2] His mother, Fannie Kaplan, died on December 31, 1947 when he was 13, and his two younger sisters, Sandra and Barbara, were sent to a foster home. Kaplan was expelled from public school after acting out, leading him to grow up as a "street kid" in the Bronx.

Kaplan did not grow up religious and was known as "Len". His family only had a small connection to Jewish practice, but he was encouraged to say Kaddish for his mother. On his first day at the minyan, Henoch Rosenberg, a 14-year Klausenburger Chassid, realized that Len was out of place, as he was not wearing tefillin or opening a siddur, and befriended him. Henoch Rosenberg and his siblings taught Kaplan Hebrew, and within a few days, Kaplan was learning Chumash.^[12]

When he was 15, Kaplan enrolled at Yeshiva Torah Vodaas, and afterwards went to the Mir Yeshiva in Brooklyn. Kaplan then studied at the Mir Yeshiva in Jerusalem in Israel, where he received semikhah from some of Israel's foremost rabbinic authorities, including Yoreh Yoreh from Rabbi Yitzhak HaLevi Herzog and Yadin Yadin from Rabbi Eliezer Yehuda Finkel in 1956.^[13]

Secular career

Upon returning from Israel in the late 1950s, Kaplan taught in Richmond, Virginia and the Bronx before moving to Louisville, Kentucky^[14]. In Louisville, he taught at Eliahu Academy and studied at University of Louisville, where he joined Sigma Pi Sigma, the Woodcock Society, and Phi Kappa Phi and eventually completed his bachelor's degree in Physics in 1961.^[15] While in Louisville, he met Tobie Goldstein, whom he married on June 13, 1961 and with whom he had nine children.^[10][17]

Kaplan then moved to Hyattsville, Maryland to study Physics at the University of Maryland and begin his first professional position as a research scientist at the National Bureau of Standards's Fluid Mechanics Division, where he was in charge of Magnetohydrodynamics research. Kaplan earned his M.S. degree in physics from University of Maryland in 1963.^[10] After graduating, Kaplan remained at University of Maryland as a National Science Foundation fellow^[19] through the fall semester of 1964.^[20][21][10]

Rabbinic career

In 1965, Kaplan switched careers and began practicing as a rabbi.

On February 19, 1965, Kaplan moved to Mason City, Iowa, where he became the Rabbi of Adas Israel.^[23][24]

B'nai Sholom (1966–1967)

On August 7, 1966, Kaplan became the Rabbi at B'nai Sholom, a Conservative synagogue^[25] in Blountville, Tennessee. He held the position through 1967.^[26][27]

Kaplan then moved to Albany, New York, where he became the Rabbi at [https://web.archive.org/web/20120711051113/http://www.ohavshalom.com/ Ohav Shalom], a Conservative synagogue.^[29] During this time, he also functioned as the president of the AJCC (Albany Jewish Community Center) and the Hillel Counselor to the B'nai B'rith Hillel Counselorship at University at Albany, SUNY.^{[10][31][32][33]}

Brooklyn (1971–1983)

In 1971 Kaplan moved to Brooklyn, New York, where he lived until the end of his life.^[10] Kaplan didn't hold any rabbinic positions in Brooklyn, but had many other positions which involved writing and editing religious publications:^[10]

• Chaplain at Hunter and Baruch colleges (New York), from 1971 to 1972,
• Associate editor of Intercom, and Orthodox Jewish Scientists, from 1972 to 1973,
• Editor of Union of Orthodox Jewish Congregations of America's Jewish Life magazine from 1973 to 1974,^[3] and
• Director of publishing at the NCSY from 1974 to 1975

Death

Kaplan died at his home of a heart attack on January 28, 1983, at the age of 48.^[17] He was buried in the Mount of Olives Jewish Cemetery, in East Jerusalem, off Aweiss street, in the part known as "Agudas Achim Anshei America", "Chelek Alef" (Portion 1).

Legacy

The Aryeh Kaplan Academy day school in Louisville, Kentucky is named in honor of Rabbi Aryeh Kaplan.^[38]

His monument says that he was successful at doing Kiruv.

Bibliography

Kaplan produced works on topics as varied as prayer, Jewish marriage and meditation; his writing was also remarkable in that it incorporated ideas from across the spectrum of Rabbinic literature, including Kabbalah and Hasidut. His introductory and background material contain much scholarly and original research. In researching his books, Kaplan once remarked: "I use my physics background to analyze and systematize data, very much as a physicist would deal with physical reality."^[39] This ability enabled him to undertake large projects, producing close to 50 books.^[4] His works have been translated into Czech, French, Hungarian, Modern Hebrew, Portuguese, Russian, German and Spanish.

Kaplan's major influence was Rabbi Zvi Aryeh Rosenfeld (1922–1978), who single-handedly introduced the teachings of Rebbe Nachman of Breslov to American shores beginning in the 1950s, inspiring many students at Brooklyn yeshivas, especially Torah Vodaas.^[4] Working together, Kaplan and Rosenfeld translated and annotated Rabbi Nachman's Tikkun (based on the Tikkun HaKlali). At Rosenfeld's suggestion, Kaplan also produced the first-ever English translation of Sichot HaRan ("Rabbi Nachman's Wisdom"), which Rosenfeld edited. He also translated and annotated Until the Mashiach: The Life of Rabbi Nachman, a day-to-day account of Rebbe Nachman's life, for the newly established Breslov Research Institute founded by Rosenfeld's son-in-law, Chaim Kramer. Kaplan's later writings further explored Hasidut, Kabbalah and Jewish meditation. (Kaplan himself utilized the meditative form of Kabbalah on a daily basis.^[42])

From 1976 onward, Kaplan's major activity was the translation into English of the recently translated (Ladino into Hebrew, 1967) anthology, Me'am Lo'ez. He also completed The Living Torah, a new translation of the Five Books of Moses and the Haftarot, shortly before his death.

Kaplan was described by Rabbi Pinchas Stolper, his original sponsor, as never fearing to speak his mind. "He saw harmony between science and Judaism, where many others saw otherwise. He put forward creative and original ideas and hypotheses, all the time anchoring them in classical works of rabbinic literature." His works reflect his physicist training—concise, systematic, and detail-oriented.^[4] His works continue to attract a wide readership, and are studied by both novices and the newly religious, as well as by scholars, where his extensive footnotes provide a unique resource.^[5]

Religious works

• The Living Torah, Rabbi Kaplan's best-known work, is a widely used, scholarly^[5] (and user friendly^[4]) translation into English of the Torah. It is noteworthy for its detailed index, thorough cross-references, extensive footnotes with maps and diagrams, and research on realia, flora, fauna, and geography (here, drawing on sources as varied as Josephus, Dio Cassius, Philostratus and Herodotus). The footnotes also indicate differences in interpretation amongst the commentators, classic and modern.^[47] It was one of the first translations structured around the parshiyot, the traditional division of the Torah text. (Moznaim, 1981, {{ISBN|0-940118-35-1}})
• "Handbook of Jewish Thought," produced early in his career, is an encyclopedic and systematic treatment of Judaism's fundamental beliefs.^[48] Because of the work's structure and detail, the references, with the index, can serve as a research resource across almost all of rabbinic literature. (Moznaim, Vol. 1, 1979, {{ISBN|0-940118-49-1}}; Vol. 2, 1992, {{ISBN|0-940118-79-3}})
• "Torah Anthology," a 45-volume translation of Me'am Lo'ez from Ladino (Judæo-Spanish) into English. Rabbi Kaplan was the primary translator.
• "Made in Heaven: A Jewish Wedding Guide" (Moznaim, {{ISBN|978-0940118119}})
• "Tefillin: God, Man and Tefillin"; "Love Means Reaching Out"; "Maimonides' Principles"; "The Fundamentals of Jewish Faith"; "The Waters of Eden: The Mystery of the Mikvah"; "Jerusalem: Eye of the Universe" — a series of highly popular and influential booklets on aspects of Jewish philosophy which span the entire spectrum of Jewish thought, as well as various religious practices. Published by the Orthodox Union/NCSY^[39] or as an anthology by Artscroll, 1991, {{ISBN|1-57819-468-7}}.
• Five booklets of the Young Israel Intercollegiate Hashkafa Series — "Belief in God"; "Free Will and the Purpose of Creation"; "The Jew"; "Love and the Commandments"; and "The Structure of Jewish Law" launched his writing career. He was also a frequent contributor to The Jewish Observer. (These articles have been published as a collection: Artscroll, 1986, {{ISBN|0-89906-173-7}})

• "If You Were God," his final work, was published posthumously in 1983. Moving beyond superficiality, the slender book encourages the reader to ponder topics concerning the nature of being and Divine providence.^[50]
• Kaplan translated and annotated classic works on Jewish mysticism — Sefer Yetzirah, Bahir, and Derekh Hashem — as well as produced much original work on the subject in English. His Moreh Ohr, a Hebrew-language work, discusses the purpose of Creation, tzimtzum and free will from a kabbalistic point of view.

Kaplan wrote three well-known books on Jewish meditation. These books seek to revive and reconstruct ancient Jewish practices and vocabulary relating to meditation. He also wrote and translated several works related to Hasidic Judaism in general, and to the teachings of Rabbi Nachman of Breslov in particular.
