According to Alexander Sharon, the Digital Library of Wielkopolska has published a list of all veterinarians in Poland in 1931. Click here for more information.
There were many Jews in the list of 1,364 Polish veterinarians.
At the website, go to page 34 in the PDF for an alphabetical listing.
Information includes: Surname, first name; practice affiliation (district - powiat; regional - sejmik, town - miasto); town location; district location; date of birth; religion (Jewish - mojzeszowa); nationality; graduation year; and university.
Sharon says that several Jewish veterinarians have native Polish-sounding surnames and first names, but that their religion is listed in column 7.
