In Jewish history, amongst the rishonim and achronim (and achrei achronim), who were known to be Talmidei Chachumim (either due to their seforim or just facts) and Businessmen (employee counts)?
I don't understand why this is marked as a duplicate of "Talmudic personages and their occupations": That question seems to be asking about people in the [Mishnah and] Talmud who had other occupations, whereas this one is asking about post-Talmudic people ("amongst the rishonim and achronim") who had other occupations.– Tamir EvanApr 30, 2020 at 15:49
@TamirEvan yup, exactly.– MosheApr 30, 2020 at 19:55
Not an exhaustive list by far, but here's a few:
Ramchal- Wikipedia claims that he was a diamond cutter. I remember reading that he made lenses and was involved in glass cutting and shaping.
Chayei Adam- merchant (he writes about it in his hakdama to chochmas adam)
Pischei Choshen (Rav Y.Y. Blau- dayan for the eide chareidis)- banker (During the hespedim given when he passed away, one of the speakers mentioned that he refused to work in rabbonus and supported himself as a banker. That's where he gained his expertise in Choshen mishpat and business matters. Eventually the Minchas Yitzchok convinced him to serve as a dayan on the Eida. I'm going to try to see if there's a source for it.)
(I believe the Levush worked in textiles, and there's a very interesting story about him fighting off a woman trying to seduce him that involved his clothing, and that's why he named his work the Levush. But I don't remember the story or where it can be found.)

This answer could be improved with your sources for these claims. Apr 29, 2020 at 18:15
@TamirEvan You're right. I quickly added a couple of sources. As I find more, I'll put them up.– BinyominApr 29, 2020 at 18:54
