The men profiled in Twelve Men are a diverse and colorful group: from Dreiser's equally famous brother, the songwriter Paul Dresser ("My Brother Paul"), to the entirely obscure railroad foreman Michael Burke ("The Mighty Rourke"), on whose work crew Dreiser had labored in 1903. The twelve narratives are compelling portraits of the men portrayed, but they also reveal many insights into Dreiser's own life and work. These factors elevate the significance of Twelve Men to a level consistent with other major works in the Dreiser canon.
