What a gem the Rosenbach is! I hadn't been to the Rosenbach for years, but my granddaughter wanted to see it. The tour guide was excellent, the staff who welcomed us filled with enthusiasm. The highlight for me is Marianne Moore's room and the great insight into the Rosenbach brothers, two of the most cultured men of their time. If you love books, the history of Philadelphia, or the world of Marianne Moore, you should visit this gem.
