Short story: I visited my grandmother (90 yo, austrian); I'm in interested in history. When it came to my mind that she actually experienced the time of the second world war and before I thought I'd ask her about that time next time I see her. Only there's not specific that I'm interested in. More lof a general curiousity thing. So I wondered if there's like a spreadsheet of questions or something historians use for interviews. Or to put it more simply:
TLDR: If a historian were to ask a ww2 witness, what would be some of the questions asked?
Not to discourage any further discussion, but there was an excellent Monday Methods thread on oral history interviews a while back kicked off by u/commiespaceinvader.
