"Hetty: the genius and madness of America's first female tycoon" by Charles Slack Harper Collins, 2004
Having learned about business and finance at her father's and grandfather's knees, Hetty Robinson used her knowledge to become this country's richest woman in the 1860s. Both before and after her marriage to Edward Green, she rigorously guarded her fortune, tying it up in trusts to prevent it from being dispersed outside her family. This account of Hetty's life, unfashionable and eccentric by her choice, illustrates the disconnect between her Quaker upbringing and the effects of her fabulous wealth on her immediate and distant family.
