Washington D.C. in the 1850s was a tale of two cities. It was the Capitol city of a rapidly expanding new nation while at the same time ground zero for a politically fractured and divided nation hurtling toward disunion. Standing in the middle of it all was Montgomery C. Meigs, a military engineer who led the construction of two massive public works projects at the same time: the expansion of the Capitol building and an aqueduct to provide water to the residents growing city. Meigs would go on to serve as Quartermaster for the Union Army under Abraham Lincoln. Meigs was an innovator, public servant, and one of the most important patriots of the nineteenth century.
