 From then until 1904 he taught at the Humboldtgymnasium, first as Oberlehrer and after 1882 as Professor.In 1904, due to poor health, the Prussian Ministry of Education forced him to retire with a pension.The pension was the same as that given to any other Gymnasium professor, and although it was surprising to others who were aware of Röhricht's fame and importance, he himself "ne sollicita point les hommages et ne rechercha pas les profitables honneures".
