In the Autobiography of Benjamin Franklin Dover Thrift edition.

Benjamin Franklin was completely supportive of educating females.

I mention this affair chiefly for the sake of recommending that branch of education for our young females, as likely to be of more use to them and their children, in case of widowhood, than either music or dancing, by preserving them from losses by imposition of crafty men, and enabling them to continue, perhaps, a profitable mercantile house, with establish'd correspondence, till a son is grown up fit to undertake and go on with it, to the lasting advantage and enriching of the family.
