Unsung Heroes: African American Innovators Whose Genius Still Shapes Southwest Virginia

 Unsung Heroes: African American Innovators Whose Genius Still Shapes Southwest Virginia




1. Alice H. Parker: The Reason We Stay Warm

In the mountains of Southwest Virginia, winter is no joke.

  • The Invention: In 1919, Alice Parker patented a gas-powered central heating furnace.

  • The Impact: Before her, people relied on wood or coal fireplaces in every room. Her design used ducts to spread heat throughout the entire house. If you are sitting in a home in Roanoke or Wytheville today with central heat, you are benefiting from her blueprint.

2. Garrett Morgan: The Traffic Light & Safety Hood

Whether you're driving down Route 11 or working in a hazardous environment, Garrett Morgan’s genius is present.

  • The Traffic Signal: He invented the three-position traffic signal (adding the "yellow" light).

  • The Safety Hood: He also invented an early gas mask. This was crucial for miners and firefighters. Given the rich history of coal mining in SWVA (places like Tazewell and Buchanan County), his "safety hood" saved countless lives in the shafts.

3. Frederick McKinley Jones: Keeping the Food Fresh

Agriculture and trucking are the lifeblood of our region’s economy.

  • The Invention: He invented the automatic refrigeration system for long-haul trucks (Thermo King).

  • The Connection: Every time you see a refrigerated semi-truck hauling produce or meat through the I-81 corridor, you’re seeing his invention in action. Without him, the "farm-to-table" supply chain in the Blue Ridge wouldn't exist as we know it.

4. Sarah Boone: The Modern Ironing Board

  • The Invention: In 1892, she patented a narrow, curved, and collapsible ironing board.

  • The Legacy: Before her, people used a simple wooden plank balanced on two chairs. She designed the board to make it easier to iron sleeves and women's garments. It’s a staple in nearly every laundry room in the region today.

Shadows of the Old Dominion: Why Virginia Is America’s Most Haunted State Dickerson/Melbourne house in Jonesville where the Union Army moved to a defensive position but saw their situation was dire and eventually surrendered to the Confederate Army, with 12 dead and nearly 400 captured.   Virginia is often celebrated as The Mother of Presidents and the birthplace of American democracy. But beneath the monuments, battlefields, and colonial streets lies another identity—one whispered in the rustle of Jamestown’s woods and the stillness of Fredericksburg’s Sunken Road. Virginia is widely regarded as America’s most haunted state , and the reasons run far deeper than ghost stories. The Old Dominion holds an unparalleled concentration of human history—triumph, tragedy, conflict, ceremony, and survival—all layered across 11,000 years. The result is a landscape where the past never fully loosens its grip. 1. Ancient Echoes: 11,000 Years of Human Presence Long before English s...

  Saturday Night in the "New York of the Hollows" By Jerry Buchanan If you looked at the census numbers for St. Charles in 1950, you’d see a modest count of 550 people. But if you stood on the sidewalk on a Saturday afternoon, those numbers lied. To us, St. Charles didn't feel like a small town; it felt like a mountain metropolis. The Saturday Swell Every Saturday, the sidewalks were so packed with miners and their families coming in from the camps—places like Bonny Blue, Kemmerer Gem, and Benedict —that you often had to step off the curb just to get around. The town was a transportation hub. We had a passenger bus running to Pennington Gap, but the real local "movers" were the taxis. The taxi stand usually had three or four cabs idling, manned by drivers like Carl Buchanan and George Gibson . Walt Gilley (related to "Blackie" Gilley) also drove for Carl from time to time. I’ll never forget the day Walt walked into the Cavalier Cafe looking for a co...

  From Lunch Pails to Free Plates: A St. Charles Journey Since 1956 By Jerry Buchanan The old brick walls of St. Charles: Where my journey began in 1956. The Heartbeat of St. Charles: A Journey Back to 1956 Looking at an old photo of the St. Charles school, I am instantly transported back to 1956, the year my journey began. While the finer details of those early years have faded like a sepia print, the rhythms of life in that building remain etched in my mind. The Midday Trek One of my most vivid memories isn’t of a lesson at a chalkboard, but of the midday bell. In those days, the cafeteria was tucked away behind the high school, but my siblings and I rarely saw the inside of it. There were no programs for free or reduced lunches then; if the cafeteria meal didn't fit the family budget, you simply went home. Rain or shine, we made the trek home for lunch. It was a testament to the times—our parents worked hard, but with multiple children, the budget was tight. I do remember one sm...
