Shmuel Brudny was an Orthodox Jewish rabbi in New York in the mid-twentieth century.

[3] He remained in Rameilles for three years before transferring to the Mir Yeshiva in 1932, where he was referred to as "the prodigy from Smarhon" and was given privileged treatment, receiving extra money from the rosh yeshiva (dean), Eliezer Yehudah Finkel.

[2][3] During World War II, the yeshiva fled to Vilna in Lithuania and later had to go into a hiding in the small town of Kėdainiai.

With much outside help, notably from Avraham Kalmanowitz and Japanese consul Chiune Sugihara, the Mir Yeshiva left Lithuania before the Nazi occupation and via Russia and Japan, resettled in Japanese-occupied Shanghai, where he studied with Chaim Shmuelevitz.

[2] After World War II, the yeshiva relocated to the United States.
