Rabbi Nachman Shlomo Greenspan (Hebrew: נחמן שלמה גרינשפן; 1878 – August 1961) was a Talmudic scholar, rosh yeshiva of Etz Chaim in London, and an author of a number of Torah works.
Greenspan was born in the village of Lyakhovichi in the Minsk Governorate of the Russian Empire (present-day Belarus), where his father Yaakov Moshe was engaged in commerce.
[citation needed] Upon the outbreak of World War I, Rabbi Greenspan fled to Britain via Belgium with his children.
Among his more well-known students were future Chief Rabbi Lord Jakobovits, Dayan Pinchas Toledano, Judge Leonard Gerber and Arnold J. Cohen.
He left many Halachic and Talmudic writings, and a large number of his written manuscripts were destroyed in the First World War.
