Joseph Seligman arrived in the United States in 1837, with the equivalent of $100 sewn into the lining of his pants. Then came the Lehman brothers, who would open a general store in Montgomery, Alabama. Not far behind were Solomon Loeb and Marcus Goldman, among the “Forty-Eighters” fleeing a Germany that had relegated Jews to an underclass.

It was the most remarkable political about-face in American history. During the Civil War, General James Longstreet fought tenaciously for the Confederacy. He was alongside Lee at Gettysburg (and counseled him not to order the ill-fated attacks on entrenched Union forces there). He won a major Confederate victory at Chickamauga and was seriously wounded during a later battle. After the war Longstreet moved to New Orleans, where he dramatically changed course.

In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.

The celebrated painter Camille Pissarro (1830-1903) occupied a central place in the artistic scene of his time: a founding member of the new school of French painting, he was a close friend of Monet, a longtime associate in Degas's and Mary Cassatt's experimental work, a support to Cezanne and Gauguin, and a comfort to Van Gogh, and was backed by the great Parisian art dealer Paul Durand-Ruel throughout his career. Nevertheless, he felt a persistent sense of being set apart, different, and hard to classify.

From Colonial America's founding settlements through the Gilded Age to the present day, Gross traces the complex legacy of American WASPs through the lives of fifteen influential individuals and their very privileged, sometimes intermarried families. As the clans progress, prosper, and periodically stumble, defining aspects in the four-century sweep of American history emerge.
