Erasmus Darwin
The last two leaves of Darwin's A plan for the conduct of female education in boarding schools (1797) contain a book list, an apology for the work, and an advert for "Miss Parkers School". The work probably resulted from his liaison with Mary Parker. The school advertised on the last page is the one he set up in Ashbourne, Derbyshire for their two illegitimate children, Susanna and Mary.
