Aharon Lichtenstein (May 23, 1933 – April 20, 2015) was an Orthodox rabbi, Israel Prize laureate[1] and rosh yeshiva[2] who was an authority in Jewish law (Halakha).

[4] He earned a BA at Yeshiva University in 1953, and semicha ("rabbinic ordination") at YU's Rabbi Isaac Elchanan Theological Seminary under Joseph B. Soloveitchik, whose daughter, Tovah, he would later marry.

[citation needed] He was committed to intensive and original Torah study and articulated a bold Jewish worldview embracing elements of modernity within the framework of a Torah life, reflecting the tradition of his teacher and father-in-law, Joseph B. Soloveitchik in line with Centrist Orthodoxy.

[10] Lichtenstein was awarded the Israel Prize for Jewish Literature on Israeli Independence Day: May 6, 2014.

[11] He was a source of inspiration for a wide circle of Jewry, for both his educational attainments and his intellectual and spiritual leadership.
