Drachman was born to parents who were immigrants from Galicia and Bavaria. After studying in a Hebrew preparatory school, Drachman earned a B.A. from Columbia College. He earned a scholarship at the Jewish Theological Seminary of Breslau where he received his rabbinic ordination. He also earned a Ph.D from the University of Heidelberg.
In 1890, Drachman began serving as rabbi in the Park East Synagogue, where he led for the next fifty-five years. Drachman was president of the Orthodox Union and professor at the Jewish Theological Seminary.
This was ironic as the works of Zecharias Frankel of Breslau, a man Drachman considered an important Orthodox leader had been condemned by Hirsch as heretical. Historically, Frankel is considered the founder or at least a forerunner of Conservative Judaism.
