Binyamin Shlomo Hamburger

Binyamin Shlomo Hamburger (Hebrew: בנימין שלמה המבורגר‏) is a rabbi and author who is regarded as an expert on the subject of minhag Ashkenaz, the customs of German and Western European Jews, and their history.

Born in Basel, Switzerland, to German parents, he currently lives in Bnei Brak, Israel.

[1][2] A number of communities affiliated with the Institute, in Israel and the United States, now follow the Ashkenaz custom.

[4] He is also the author of the 1989 book משיחי השקר ומתנגדיהם (Meshichei Ha-Sheker U-Mitnagdeihem, False Messiahs and their Detractors), a historical work detailing many of the people who claimed to be the Jewish messiah, as well as a multi-volume work on the Yeshiva in Furth.

[2] A second edition of משיחי השקר ומתנגדיהם was published in 2009; in the foreword Hamburger records the negative reception (including book burning) of the work by some groups when it first appeared.
