— This is very sad news. Mike was a wonderful scientist and a great colleague, with which we worked construvctively and always in good harmony for many years with INTEGRAL, in the TAC, in the IUG and in a variety of other capacities connected with our observatory. I had not been aware that he was so gravely ill, and it is very sad to hear htat he has passed away.
Please forward my condolences to his wife and family.

My thoughts are with his wife, children and family.

— please, bring our condolences to the family and all Russian colleagues from the whole IBIS team.
I had the priviledge to work with Mike for some time at the beginning of the survey and had a constructive exchange with him at his IUG time. As you all know was a very talented scientist, front line men and great person… he left an abyss for all of us.
