Johann Friedrich Grael

Johann Grael (9 January 1708 - 27 September 1740) was a German architect, one of the most important architects working under Frederick William I of Prussia. Grael was put in charge of rebuilding the structure but in 1733 it was reassigned to Gerlach, citing his failure to meet deadlines. In his last years Grael worked as a consultant and a designer to various projects but -thanks to his sudden death in Bayreuth - these were completed by J. G. Weise.
