Marie Stopes (1880-1958) is chiefly remembered as a birth control pioneer and sexologist, but in her twenties and thirties she carved out a highly successful career as a palaeobotanist and coal geologist. This paper outlines her early geological research on coal balls—carbonate concretions found within the Carboniferous coal seams of northern England, which preserve the remains of the peat-forming plants in beautiful anatomical detail. Stopes worked on coal balls during three intervals of her career. In the first phase (early 1903), she was Francis Oliver's postgraduate research assistant at University College London, during the critical period leading up to the ‘discovery of pteridosperms’ with D. H. Scott. Stopes's role was to hunt down key specimens in coal ball collections scattered across Britain. In the second phase (late 1904-1907), which followed a year of doctoral research in Munich, she grappled with the more broad-ranging questions of the origin of coal balls, their stratigraphic distribution, ...
