What Elsner's view of teaching was may be gathered from one of his letters to his pupil.

The gist of his remarks lies in this sentence:-- That with which the artist (who learns continually from his surroundings) astonishes his contemporaries, he can only attain by himself and through himself.
Elsner had insight and self-negation (a rare quality with teachers) enough to act up to his theory, and give free play to the natural tendencies of his pupil's powers.

That this was really the case is seen from his reply to one who blamed Frederick's disregard of rules and custom:-- Leave him in peace [he said], his is an uncommon way because his gifts are uncommon.

He does not strictly adhere to the customary method, but he has one of his own, and he will reveal in his works an originality which in such a degree has not been found in anyone.
The letters of master and pupil testify to their unceasing mutual esteem and love.

Those of the master are full of fatherly affection and advice, those of the pupil full of filial devotion and reverence.
