Whitney and his daughter Dorothy, charter members of Ward McAllister’s Four Hundred, were personally endearing people, whose warmth of personality created a circle of affection around them. Moreover, both of them were intelligent and exceedingly able. But as Swanberg makes clear in this rich dual biography, there the similarity ended. As a businessman, Whitney was not so savory. He wasn’t quite in the robber-baron class: his arena for larceny—New York’s surface transit system—was too small. But by 1900 he had built himself a considerable fortune by fleecing small investors with watered stock and “wholesale stockjobbery.” His financial schemes were so arcane that few people in his lifetime could fathom their impropriety. And little has turned up since to untangle the mess.
