Stephen Ambrose

Building a transcontinental railroad, writes the prolific historian Stephen Ambrose, was second only to the abolition of slavery on Lincoln's presidential agenda. Through an ambitious program of land grants and low-interest government loans, he encouraged entrepreneurs such as California's "Big Four"--Charles Crocker, Collis Huntington, Mark Hopkins, and Leland Stanford--to take on the task of stringing steel rails from ocean to ocean. The real work of doing so, of course, was on the shoulders of immigrant men and women, mostly Chinese and Irish. These often-overlooked actors and what a contemporary called their "dreadful vitality" figure prominently in Ambrose's narrative, alongside the great financiers and surveyors who populate the standard textbooks.
