Grenville Dodge

Major General Grenville Dodge was a soldier, engineer, and railroad builder whose work was central to opening the American West. Introduced to railroading as a teenager while laying track on a local farm, Dodge quickly discovered his life’s calling. He pursued engineering studies in New Hampshire and Vermont, becoming a skilled surveyor before moving west to work on major railroad projects. In the 1850s, Dodge surveyed routes across Iowa and selected Council Bluffs as a key Missouri River terminus, where he became acquainted with railroad lawyer Abraham Lincoln.

During the Civil War, Dodge commanded the Fourth Iowa Volunteer Infantry and oversaw reconstruction of vital bridges and rail lines. He was promoted to general for his bravery in battle. In 1866, Dodge became chief engineer of the Union Pacific Railroad. Construction surged under his leadership, culminating in the 1869 driving of the golden spike at Promontory Summit which united the nation by rail and reshaped America’s economic and geographic future.
