Margaret Cavendish, Duchess of Newcastle-upon-Tyne (1623 – 1673) was a poet, philosopher, writer, playwright, and scientist!
She published under her own name when it was not very acceptable to do so (most woman had to publish anonymously). She even wrote a science-fiction romance novel titled The Blazing World. In addition to her 21 published works ranging in subjects from natural philosophy and modern science to romance and poetry, she was one of the very first animal advocates.
