And I've just learned that he's died last year.
So, in the spirit of making people's passing not-totally-sad (as in, it's better that they've existed and died compared to them not existing at all), some anecdotes about Dr. Włodzimierz Borkowski:
He specialized in neonatology. I don't remember how I know this, but one of the reasons for that was that he himself had joint problems that made walking over non-level surfaces hard for him that were caused by some perinatal issues.
He would treat his patients, whether young or adult, as people who should know what he's thinking. Apart from him actually answering questions of children (and not just saying something to make the child be satisfied), he'd point-blank admit when he didn't know something, or wasn't sure. (This created very polarized opinions about him among patients.)
So, something that happened at least once to my parents was that we went to see him (I don't remember what the problem was anymore, probably something related to pollen allergy); he in the end didn't have a good guess on the underlying cause, so he said so, gave some advice on symptom avoidance, asked us to try to make some observations, and to come back in 2 weeks or so. A few days later my parents got a phonecall: he thought about it in the meantime and had a new idea, that he wanted them to try.
