Henry L. Smith's X-Ray Experiments
Davidson, Mecklenburg County, North Carolina
Marker Inscription
X Ray Experiments. Prof. Henry L. Smith pioneered medical uses for x-rays. Conducted experiments and made radiographs Feb. 1896 in physics lab nearby.
Erected by North Carolina Department of Cultural Resources
The Story
Only weeks after Wilhelm Röntgen announced the discovery of X-rays, Davidson College professor Henry L. Smith was already experimenting with them in his physics laboratory. In February 1896 he produced radiographs and explored their medical uses, famously imaging a bullet lodged in a corpse's hand. His work placed a small Carolina college at the frontier of a revolutionary new science.
Why it matters
Smith's early experiments show how quickly American researchers seized on X-rays, a breakthrough that would transform medicine worldwide.
The story behind this marker
AI contextThe era
In the last weeks of 1895, a German physicist named Wilhelm Röntgen noticed that a mysterious kind of ray could pass straight through flesh and expose the bones beneath. He called them X-rays, for the unknown, and the news raced around the world by telegraph and journal in a matter of weeks. It was the kind of discovery that made even distant scientists drop what they were doing.
Davidson, North Carolina, in early 1896 was a quiet college town north of Charlotte, built around a small Presbyterian school. It was not the sort of place you would expect to sit at the leading edge of physics. Yet the late nineteenth century was an age when a single determined professor, a good laboratory, and a spark coil could put a village on the map of modern science.
The Progressive era prized exactly this kind of practical curiosity — the belief that new knowledge should be put quickly to human use. A ray that could reveal a broken bone or a lodged bullet was not just a marvel; it was a tool. At Davidson, that idea found a willing experimenter almost immediately.
People & events
Henry Louis Smith was a professor at Davidson College, a teacher of the physical sciences with the tinkerer's instinct that the new physics rewarded. When word of Röntgen's rays reached him, he did not wait for permission or for finer equipment. He set to work with the apparatus already in his physics laboratory.
By February 1896 — only weeks after the discovery was announced — Smith was producing radiographs of his own, among the earliest made anywhere in America. He was especially drawn to the medical promise of the rays, the ability to see inside the living body without cutting it open. In an era when a surgeon hunting for a bullet or a shattered bone worked largely by touch and guess, that was close to miraculous.
What makes the story remarkable is the speed of it. There was no established method to copy, no supplier of ready-made equipment, no textbook. Smith worked out by trial and patience how to coax an image from the rays, joining a tiny international fellowship of people who, in the first months of 1896, were teaching the world how to see through skin.
Its place in the American story
The X-ray is one of those rare discoveries that changed medicine almost overnight, and its American story is not only a tale of big-city hospitals and famous laboratories. It is also a story of small colleges and curious professors who read the news and reached for their equipment.
Smith's experiments show how fast a genuine breakthrough could travel and take root in the United States. Within a single winter, a technology born in a European laboratory was being tested in a Carolina college town, aimed squarely at the practical problem of healing the human body. That eagerness to seize a new idea and put it to work is a recurring thread in American innovation.
Every time a doctor today orders an X-ray to check a fracture or find a swallowed object, they are drawing on the same insight that a Davidson professor was chasing in February 1896. The marker honors not just one man's experiments but the larger moment when medicine gained the power to look inside us.
If you visit
You are standing in the heart of a classic Southern college town, where brick and shade trees and the rhythm of the academic year still set the tone. Take a moment to picture the campus as it was in 1896 — gas or early electric light, a modest physics lab, and a professor bent over a glowing tube.
As you read the marker, let the timeline sink in. The rays it commemorates were discovered only weeks before the experiments it describes. Few historic markers capture a moment when a town was, briefly, at the very frontier of world science.
Davidson makes an easy stop on a drive through the Charlotte region, and it pairs naturally with a walk around the college grounds. Bring the marker's story with you: it turns an ordinary campus stroll into a visit to one of the birthplaces of American medical imaging.

McLaughlin
Mecklenburg County, NC
This marker commemorates the Rev. Isaac Grier McLaughlin (1820–1906), a Presbyterian minister licensed to preach in 1848 who spent a remarkable half-century in the pulpit. He served congregations at New Lebanon in what is now West Virginia and, for four decades, at Back Creek in North Carolina. His long tenure spanned the antebellum years, the Civil War, and Reconstruction, ministering to a rural Piedmont community through the century's upheavals.
W. R. Odell
Concord, NC
W. R. Odell was a leading textile manufacturer in the Cabarrus County mill country and served in the state senate from 1905 to 1907. He built his career during the Piedmont's great cotton-mill boom, when the region became the heart of Southern textile manufacturing. Known as a friend of education, he lived a block west of this marker.
Barium Springs Home For Children
Iredell County, NC
In 1891 the Synod of North Carolina opened the Presbyterian Orphans' Home on this Iredell County site, part of a wave of church-founded orphanages that spread across the post-Reconstruction South to care for children left without parents. The Reverend Jethro Rumple, a prominent Presbyterian minister and historian, served as the first chairman of its Board of Regents. Later renamed Barium Springs Home for Children, the institution grew into a lasting refuge and school for generations of young people.
Barber-Scotia College
Concord, NC
Founded in 1867 by the Rev. Luke Dorland under Presbyterian auspices, Scotia Seminary set out to educate Black women in the wake of emancipation. In 1930 it merged with the Barber Memorial Institute to form Barber-Scotia College, and it opened to men in 1954. For generations it trained teachers and leaders across the segregated South.
