I just came across an article about him, posthumously, in his blessed memory - IN MEMORY OF IGOR BORISOVICH CHELPANOV (По русски)
It’s interesting that I noticed in this block of mine that he is my last authority HERE, 3 months after his death, which I only found out about now (4 years after..).
He had the greatest talent - Teacher of PhD students. I found him myself after a presentation (about the dynamics of robot grasping devises) made by one of his students, S.N. Kolpashnikov.
This was a turning point in my career (he was my dissertation supervisor) and my entire professional life!
I am immensely grateful to Igor Borisovich and remember him forever!
