All the Offenbach neophytes were buried in the city cemetery, though some years later this cemetery began to interfere with plans to expand the town, and it was ultimately liquidated in 1866. The bones of those buried there were carefully collected and respectfully reburied elsewhere. Jacob Frank’s skull was removed from his grave, and, thoughtfully recorded as “a skull belonging to a Jewish patriarch,” it passed into the hands of the historian of the city of Offenbach. Many years later, under unknown circumstances, it made its way to Berlin, where it underwent detailed measurement and research and was labeled a prime example of Jewish racial inferiority. After the Second World War, it vanished without a trace—either it was destroyed in the turmoil and chaos of war, crumbling to dust, or else it is still lying around somewhere in the underground storage facility of some museum.
