"One of them writes: "He conversed with us in our own language, took interest in every blow dealt us by pupils of the Philantropin, checked on the class of the stamps we exchanged, gave a rigorous examination to our footballs-in brief, he was our intimate." Another one relates : "He never raised his voice to a pupil. If he traveled to another city, he would say to him, 'Behave so that they will see you are a pupil of Rabbi Hirsch.' He influenced them by his personality; the look of his burning eyes was engraved deep in the memory of those he had educated.""
