Maria Sibylla Merian
Maria Sibylla Merian (2 April 164713 January 1717) was a German-born naturalist and scientific illustrator, a descendant of the Frankfurt branch of the Swiss Merian family. Merian was one of the first naturalists to observe insects directly.
Maria of Orange-Nassau (1642–1688)
Maria kept up a correspondence with her two surviving sisters after her marriage. Like her sisters Louise Henriette with the Oranienburg, Albertine Agnes with the Oranienstein and Henriette Catherine with Oranienbaum, Maria built herself a new palace after her marriage - she completed hers in 1669 at Bad Kreuznach and named it Schloss Oranienhof. Maria died in 1688 after six days of pneumonia and Schloss Oranienhof was destroyed by French troops in the Nine Years' War a year later.
