Was there someone in particular who is credited with turning "cooking with gas" (doing something fast, efficiently, with great results) into the German/Yiddish "cooking mit gas"? Or should I say, popularizing it. It seems to have been a little bit of a catch-phrase-- branching off from another catch-phrase.
My mom (born 1925 in Illinois) brought it up. She had some older German-American relatives, but I'm thinking maybe somebody in radio or movies liked to use the phrase?
Of course there is a sickening Holocaust image which comes to mind now, spoiling the cuteness of the German OR Yiddish version-- whichever it would be.
Just the other day, I heard a skit from "Good News of 1940" where Lou Holtz and Fanny Brice are among the "British" characters, and "Now we're cooking with gas!" is one of the lines.
