It sounds like a tall tale from a campfire. A guy with blue skin living in the hills of Kentucky, hiding away from a world that wouldn't understand. But it's real. Honestly, the story of the Fugate family and the rare condition that turned their skin the color of a summer bruise is one of the most fascinating intersections of genetics and social history in American medicine.
People usually stumble onto this topic and think it’s some kind of Internet hoax. Photoshopped, right? No. It’s a very specific medical reality called methemoglobinemia.
Who Was the Original Guy with Blue Skin?
The story actually begins in 1820. Martin Fugate, a French orphan, settled in Troublesome Creek, a remote corner of eastern Kentucky. Martin was the original guy with blue skin in the region, though historical records suggest he wasn't "Avatar" blue—more like a pale indigo or a light plum.
He married a local woman named Elizabeth Smith. Here’s the crazy part: by sheer genetic coincidence, Elizabeth carried the exact same rare, recessive gene that Martin did. In a tiny, isolated community where families stayed put for generations, the "blue" gene didn't just survive; it thrived. Out of their seven children, four were reportedly born with blue skin.
The Science: Why They Turned Blue
We need to talk about blood. Most of us have red blood because of hemoglobin, which carries oxygen. But in the case of the Fugates, they suffered from a deficiency of an enzyme called cytochrome-b5 methemoglobin reductase.
Basically, their hemoglobin was replaced by methemoglobin. This version of the molecule is less effective at releasing oxygen to the body's tissues. When your blood is saturated with methemoglobin, it loses that bright red hue and turns a dark, chocolatey brown. Through the skin, that brown-ish blood looks distinctly blue.

- The Genetic Factor: It’s an autosomal recessive trait. You need a copy from both parents.
- The Environment: The isolation of Troublesome Creek meant the gene pool stayed very small.
- The Outcome: Blue skin, but strangely enough, most of the family lived long, healthy lives.
Paul Karason and the Silver Mistake
If you’ve seen a more modern photo of a guy with blue skin, you’re likely looking at Paul Karason. This is a completely different situation from the Fugates. Karason wasn't born blue; he made himself blue.
He suffered from a condition called argyria. It happened because he spent years consuming colloidal silver and rubbing silver preparations on his face to treat dermatitis. Silver is a metal. When you ingest too much, it deposits in your skin and organs. Once it’s there, sunlight causes it to react—much like old-school photography film—turning the skin a permanent, deep grayish-blue.
Karason became a media sensation in the late 2000s. He was often called "Papa Smurf," a nickname he reportedly hated at first but eventually accepted. Unlike the Fugates, whose blue skin could actually be "cured" or managed, argyria is largely permanent.
How Do You Actually Treat Blue Skin?
It sounds counterintuitive, but the "cure" for the Fugates’ blue skin was more blue. Specifically, methylene blue.
In the 1960s, a hematologist named Dr. Madison Cawein heard rumors of the blue people and went hunting in the Kentucky hills. He eventually met Patrick and Rachel Stacy, descendants of the Fugates. He treated them with a dose of methylene blue dye.

It worked like magic.
Within minutes, the blue tint faded. The dye acted as an electron donor, helping the body convert methemoglobin back into normal, oxygen-carrying hemoglobin. It was a temporary fix—they had to take pills regularly—but for the first time in over a century, the guy with blue skin could walk into town and look like everyone else.
Living with the Stigma
Isolation wasn't just a geographical choice for these families; it was a survival tactic. People are mean. In the 19th and early 20th centuries, "blue" was seen as a mark of shame or a sign of inbreeding, even though the genetic reality was more about bad luck and a limited dating pool.
Benjamin Stacy, born in 1975, was the last known descendant to be born noticeably blue. When he arrived at a hospital in Lexington, doctors nearly called for a medical evacuation before his grandmother explained the family history. As Benjamin grew, he lost the blue tint, though his fingernails and lips would still turn purple when he got cold or angry.
Modern Cases and Warnings
Methemoglobinemia isn't just a historical curiosity. It can be "acquired" today through exposure to certain chemicals.

- Benzocaine: Found in some numbing gels.
- Nitrates: Often found in contaminated well water (leading to "Blue Baby Syndrome").
- Certain Antibiotics: Dapsone is a known trigger.
This isn't just about looking different. While the Fugates adapted, acute methemoglobinemia can be fatal if the oxygen levels in the blood drop too low. If you or someone you know suddenly develops a bluish tint to the lips or skin after taking medication, it is a genuine medical emergency.
What We Can Learn From the Blue Fugates
The story of the guy with blue skin teaches us about the "founder effect" in biology. When a small group of people starts a new population, their specific genetic quirks become the blueprint for everyone who follows.
It’s also a reminder that "rare" doesn't mean "impossible." The Fugates weren't monsters or aliens. They were a family that happened to carry a rare metabolic glitch. Today, the blue Fugates have largely blended back into the general population. Their genes are still out there, but because they’ve married people from outside the creek, the recessive trait has been pushed back into the shadows.
If you are researching this for health reasons or simply out of curiosity, keep a few things in mind. First, check your water source if you live in a rural area; high nitrates are the most common cause of "blue" symptoms today. Second, be wary of "miracle cures" involving silver. Paul Karason’s story is a tragic example of how unregulated supplements can fundamentally change your biology in ways you can't undo.
Actionable Steps for Further Understanding
If you suspect a genetic skin condition or are worried about methemoglobinemia, here is what you should actually do:
- Check Your Meds: If you use topical anesthetics like benzocaine frequently, be aware of "cyanosis" (bluing of the skin) as a side effect.
- Water Testing: If you use a private well, have it tested for nitrates annually, especially if you have infants in the house.
- Genetic Counseling: For those with a family history of rare blood disorders, a simple blood test can identify if you are a carrier of the reductase deficiency.
- Historical Research: Look into the work of Dr. Madison Cawein via the University of Kentucky archives if you want to see the original medical charts and color scales used to track the Fugate family’s progress.
