The first bat mitzvah ceremony was celebrated by Judith Kaplan Eisenstein, daughter of American rabbi, Mordechai Menachem Kaplan, founder of the Reconstructionist Branch of Judaism, in 1922. Judith’s ceremony was modelled after the bar mitzvah. Traditional Jewish communities do not formally celebrate bat mitzvah (“daughter of the commandments”), when Jewish girls turn twelve.
