Dynasty of Death — Taylor Caldwell

An epic multigenerational saga stretching from 1837 to the eve of World War I, about the Bouchard and Barbour families, who grow their small munitions factory into a great international corporation.

Joseph Barbour is a servant, who becomes a successful businessman and arms manufacturer. His son Martin is not interested in money, he is an idealist and altruist. Ernest, the elder son, is an egoist and believes that money is the greatest power in the world. Ernest loves Amy Drumhill, the niece of Gregory Sessions, owner of a steel factory. However, she marries Martin, who establishes a hospital, and dies in the American Civil War. Ernest's hardness ruins Joseph, and he is cursed by his mother.

This story of the Bouchard clan is continued through World War II in Caldwell's later novels The Eagles Gather (1940) and The Final Hour (1944), although the Pittsburgh setting is largely left behind as the family takes its place on the world stage
