" If the ‘heathen’ — that is, the German and the French teachers — were regarded with little respect, the teacher of writing, Ebert, who was a German Jew, was a real martyr. To be insolent with him was a sort of chic amongst the pages. His poverty alone must have been the reason why he kept to his lesson in our corps. The old hands, who had stayed for two or three years in the fifth form without moving higher up, treated him very badly; but by some means or other he had made an agreement with them: ‘One frolic during each lesson, but no more’ — an agreement which, I am afraid, was not always honestly kept on our side.
One day, one of the residents of the remote peninsula soaked the blackboard sponge with ink and chalk and flung it at the calligraphy martyr. ‘Get it, Ebert!’ he shouted, with a stupid smile. The sponge touched Ebert’s shoulder, the grimy ink spirted into his face and down on to his white shirt.
We were sure that this time Ebert would leave the room and report the fact to the inspector. But he only exclaimed, as he took out his cotton handkerchief and wiped his face, ‘Gentlemen, one frolic — no more to-day! The shirt is spoiled,’ he added in a subdued voice, and continued to correct someone’s book.
We looked stupefied and ashamed. Why, instead of reporting, he had thought at once of the agreement! The feelings of the whole class turned in his favour. ‘What you have done is stupid,’ we reproached our comrade. ‘He is a poor man, and you have spoiled his shirt! Shame!’ somebody cried.
The culprit went at once to make excuses. ‘One must learn, sir,’ was all that Ebert said in reply, with sadness in his voice.
All became silent after that, and at the next lesson, as if we had settled it beforehand, most of us wrote in our best possible handwriting, and took our books to Ebert, asking him to correct them. He was radiant, he felt happy that day.
This fact deeply impressed me, and was never wiped out from my memory. To this day I feel grateful to that remarkable man for his lesson. "
