Jewish Roots of Poland [638]
No, this was during Polish independence.
In that case I see several possibilities:
1. Your father's colleague made it all up.
2. Your father's colleague misinterpreted his father's words.
3. His father made it all up.
4. His father didn't know why he was denied employment and simply assumed that it was due to antisemitism.
5. Your father's colleague wanted to make himself seem more important by stating that he hails from a family of doctors and not, say, farmers or building constructors.
6. His father competed for a job with a catholic and lost. Bitter, he blamed it on antisemitism.
7. The director of the hospital was antisemitic and didn't want to employ Jews so he lied that he's not allowed to do so by law.
Whichever one is true, the only way of proving him wrong is to present him with a list of Jewish doctors in pre-war Poland. The law was universal for the whole country so you don't have to search for them specifically in Tarnopol. My advice is to show him at least one full page of surnames, he won't be able to ignore that many. However, there's a possibility that he's simply too proud to admit that he was wrong or lying in which case he will never admit it, no matter how much evidence you present him with.
Also, from en.wikipedia.org/wiki/History_of_the_Jews_in_Poland
The major industries in which Polish Jews were employed were manufacturing and commerce. In many areas of the country the majority of retail businesses were owned by Jews who were sometimes among the wealthiest members of their communities. Many Jews also worked as shoemakers and tailors, as well in the liberal professions; doctors (56% of all doctors in Poland), teachers (43%), journalists (22%) and lawyers (33%)Hospitals would have to be seriously understaffed if 56% of doctors were refused employment.
