 Max Herz was an outstanding historian of architecture but his heavy workload at the Comité did not allow him to develop his capacities in this field to the level of his abilities and desires.At the same time, all his publications are worthy of our attention, because they were written by a highly gifted and well educated specialist who lived among the monuments of Cairo over the course of 35 years, in everyday contact and continuous interaction with them.He subjected many of them to interventions of varying degrees, ranging from thorough examination to complete reconstruction.
