The Rabbinical Conference of Brunswick was a conference held in 1844 in Brunswick, convoked by Levi Herzfeld and Ludwig Philippson. Other attendees included Solomon Formstecher, Samuel Hirsch, Mendel Hess, Samuel Holdheim. Although he did not attend due to impending death, following the conference Áron Chorin, on his death-bed, wrote a declaration of his support of its conclusions. The following summer a synod at Frankfort-on-the-Main heard reports commissioned by the Brunswick session that dealt with various liturgical, practical, and theological topics. At this 1845 synod rabbis attending it declared that women count in a minyan, a formalization of a customary Reform practice dating back to 1811.
