The article posted by @maccrogenoff above was fascinating to me. Very disappointing to know that HBO’s new Julia Child series gets so much wrong. There’s a feast of accurate information that the series could have used.
Since you mentioned being disappointed in the set design of the series @eugenep, I wonder if you had seen Julia Child’s real-life kitchen, which you can visit at the Smithsonian’s National Museum of American History. Lots of photos and history at the link above if you are curious. Julia’s actual kitchen in her Cambridge, Mass. home was simple and practical.
