This is a really good point. My wife and I produce a history podcast where, right now, a lot of it draws on primary sources such as letters, diaries, etc. from the late 1800's to early 1900's. The ones in German she translates into English, but it feels "wrong" to change someone's words that are already in English.
The net result is that it's easier (for me) to understand a letter written by someone in a translated foreign language than one written by someone in English from the same period.
What’s been your favorite episode to put together?
It's hard to pick a favorite - everyone brings their own perspective to their time. One of my early favorites was 'A Jew Who Stood Guard for Hitler'[1], the account of a kid who joined the Nazis for a while - till they found out he was Jewish and kicked him out. Ah, the naivety of youth.
