In the summer of 2020 I drew this sketch of him from a photo I found on the net. I had posted the picture to him at the time to ask, if I may post on social media and if he was happy with the likeliness of the portrait.
He was so kind to write that it is ok to post it and the likeness was very good (gently correcting my English ♥️).
We all learned so much from him. He influenced our way of communicating within the class very much, stressing clarity and comprehensibility.
