"Jurek was a ubiquitous person, in all ways sociable, he constantly acquainted people with one another and liked to be in the center of attention. He was extroverted, he felt best in company, which he liked to surprise with his funny sayings and stories and often controversial opinions on various life topics. He also liked to talk about himself and his achievements and belonged to a small group of people who took care of writing down the details of their biography and continually supplementing it with descriptions of subsequent events. Obtaining further awards or honorable functions was carefully recorded. When I once asked if it wasn't a waste of time for him, he retorted with his inborn charm and a specific sense of humor: "... of course not, this will be another line to my obituary. And yet, my dear, there are many indications that you will take part in writing it, so be happy that just in case you will have something like ready "crib sheet" and above all "first hand" data so at least you won't mess up anything." Jurek's prophetic words, it was so, I did not have to look for that data because I had it in my computer."
