Despite a really impressive answer from Sgurr that fitted the clue perfectly, it was Mary Somerville’s “ground breaking” Physical Geography, in use as a the definitive standard textbook for nearly sixty years, that I was thinking of.
Coincidentally, both Mary Slessor and Mary Somerville have featured on bank notes.
