Benjamin Feigenbaum (August 12, 1860 – November 10, 1932) was a Polish born Yiddish socialist, newspaper editor, translator, and satirist.
Feigenbaum was an associate editor of the Yiddish language papers The Forward, its predecessor Di Arbeter Tsaytung, and the literary monthly Di Tsukunft and a pioneer of the Socialist Party of America.During Jewish Holiday of Yom Kippur in 1899, Feigenbaum famously said in alternative event "If there is a God and if he is Almighty as the clergy claims he is, I give him just two minutes’ time to kill me on the spot, so that he may prove his existence!" after two minutes he declared "See! There is no God!".
Afterwards he announced a location for the workers to eat instead of fasting, as traditionally done during Yom Kippur.
