History from below uncovers overlooked protagonists contributing to (inter)national endeavour often against considerable odds. Mrs T. Edward Bowdich then Mrs R. Lee (1791–1856) is indicative. When women allegedly cannot participate in early nineteenth-century scientific exploration, discovery and publication, Sarah's multiple specialist contributions to French and British natural history have attracted no book-length study. This first appraisal of Sarah's unbroken production of discipline-changing scientific work over three decades – in modern ichthyology, in historical geography of West Africa and in the next-generational dissemination of expert scientific knowledge – does more than fill this gap. The book also pivotally investigates the intercultural, interdisciplinary and multi-genre reach of Sarah's pioneering perspectives and contributions, and how she could achieve her work independently in her own name(s) over three decades. Sarah's larger significance is then to provide a very different narrative for women at work in expert nineteenth-century natural history-making. By everywhere challenging the secondary, minor and domestic frames for women's contributions of the period, the pioneering perspectives of Sarah's story also provide alternative paradigms to the 'leaky-pipeline' modelstill informing women's careers and work in STEM(M) today.

History from below has particular advantages. It uncovers overlooked protagonists in (inter)national endeavour for their importance and wider significance, and plots triumphs of discovery and contribution to knowledge where they are supposed not to occur. One such figure is (British-born) Sarah née Wallace, Mrs T. Edward Bowdich then Mrs R. Lee (1791–1856). Despite her multiple contributions to new natural history and its publication in both France and Britain in the first half of the nineteenth century, no monograph study has attended to her life's workin independent natural history-making for its interdisciplinary range and perspectives, or explored its intercultural significance through the double contexts of expert French and British natural history and publication.
