The Story
When the United States entered the First World War in 1917, William Sims commanded American naval forces operating in European waters, coordinating with the Royal Navy against the German submarine campaign that was strangling Allied shipping. A sharp-penned naval writer and reformer, he had left this small Huntingdon County community for the U.S. Naval Academy back in 1876, and his family lived in the house opposite this marker for nearly two decades. His career bridged the age of sail-trained officers and the modern steel navy that fought a global war.
Why it matters
Sims embodies how figures from small American towns helped shape the country's emergence as a world naval power during World War I.
The story behind this marker
AI contextThe era
William Sims's story begins in a small community in Huntingdon County, in the ridges and valleys of central Pennsylvania — far from any ocean. Yet from here, in 1876, a young man set out for the U.S. Naval Academy and a life at sea. His family lived in the house opposite this marker from 1883 to 1902, anchoring him to this quiet corner of the state even as his career carried him across the world.
His lifetime spanned an extraordinary transformation in naval power. When he entered the service, warships still bore the traditions of the age of sail; by the height of his career, navies were steel, steam-driven, and armed with weapons of a wholly new order. Sims came of age precisely as the modern navy was being invented.
That sweep — from a landlocked Pennsylvania town to the command of American naval forces in a world war — is the backdrop against which the marker asks you to remember him.
People & events
Sims made his name partly as a reformer and a critic. He was a naval writer unafraid to point out where the service fell short — in gunnery, in ship design, in readiness — and that willingness to challenge comfortable habits helped push the American navy toward modern standards. It's a rarer kind of courage than battlefield bravery, and it shaped him.
When the United States entered the First World War in 1917, that reputation carried him to the top. He was placed in command of American naval forces operating in European waters, where the central threat was the German submarine campaign — the U-boat war that was sinking Allied ships faster than they could be replaced and threatening to starve Britain into surrender.
Sims's work was as much cooperation as combat: coordinating closely with the Royal Navy, helping knit American and British efforts into a single response to the submarine menace. It was a war fought through convoys, escorts, and hard coordination across an alliance, and he stood at the center of the American part of it.
Its place in the American story
Sims embodies a larger truth about the era: this was when the United States stepped onto the world stage as a genuine naval power, its fleet and its officers now central to a global war rather than a regional afterthought.
His career also captures the human side of that rise. The country's emergence as a sea power was built on individuals — many from small inland towns with no seafaring tradition at all — who trained hard, argued for reform, and then shouldered enormous responsibility when the moment came. That a boy from a Huntingdon County community could rise to command American naval forces in European waters says something about the opportunities and the demands of the age.
The cooperation he helped lead mattered too. Fighting the submarine campaign required allies to pool their ships, ports, and plans, and that habit of joint operation would echo through the century of alliances that followed.
If you visit
The pleasure of this stop is the contrast. You're deep in the ridges and valleys of central Pennsylvania, about as far from a saltwater harbor as you can get — and yet this is the boyhood community of a man who would command American naval forces across the Atlantic. Let that distance sink in as you read the marker.
Look to the house opposite, where his family lived for nearly two decades. It's an ordinary building in an ordinary town, which is exactly what makes it worth a moment: great national careers often begin behind very plain front doors.
Rockhill and the surrounding countryside reward slow travel, and this marker adds a surprising thread — a naval story tucked into the mountains — to a day of exploring the region. Stand here, imagine the young man leaving for the Naval Academy in 1876, and let the small town open onto the wide ocean.

McCoy Home
Lewistown, PA · est. 1967
This Lewistown home was the birthplace of Frank R. McCoy, a West Point graduate whose long career carried him from the Spanish-American War through both World Wars. A soldier-diplomat as much as a general, he served on international commissions and led the Foreign Policy Association, helping shape how Americans understood their growing role in the world. His life spanned the era in which the United States rose to global power.
28th Division Shrine
Harris Township, PA · est. 1947
Pennsylvania's 28th Infantry Division traces its lineage to 1917, and it went on to earn a fierce reputation in the trenches of the First World War and again in the hedgerows and forests of the Second. Colonel Theodore Boal founded this hillside shrine to honor the division's fallen, and Pennsylvania made it an official state memorial in 1932. The site gathers the memory of two generations of Keystone State soldiers into one place of reflection.
Bedford Furnace
Cromwell Township, PA · est. 1947
Completed around 1788, Bedford Furnace was the first iron furnace in the Juniata region, launching an industry that would define central Pennsylvania for generations. Built along Black Log Creek, it produced charcoal iron—smelted using vast quantities of hardwood charcoal from the surrounding forests—and became renowned for quality. It stood at the leading edge of the young nation's westward-spreading iron industry just as the Constitution was being ratified.
Juniata Iron
Cromwell Township, PA · est. 1947
Between 1790 and 1850, the streams of the Juniata region powered dozens of charcoal iron furnaces and forges whose ruins still dot the landscape. Juniata iron earned a reputation as the finest in America, prized for its purity and strength in an age before industrial steelmaking. The industry's reign ended in the mid-19th century as ironmakers shifted to coal and coke fuel, drawing production toward the coalfields and cities.
