Mistress of science: the story of the remarkable Janet Taylor, pioneer of sea navigation

It is hard to imagine a more male-dominated field in the nineteenth century than that of sea navigation; this was the high-point of the British Empire and sea navigation drove it. Yet in the midst of this domain Janet Taylor emerged as a young woman confident of her ability to match the best male minds in the business. Janet was one of the most remarkable scientists of the nineteenth century, and yet until now her story has never been told. A gifted mathematician, astronomer, author and instrument maker, Janet also possessed extraordinary skills as a teacher of navigation and business woman.
