You probably haven't thought about Great Lakes Carbon Company today. Honestly, most people haven't thought about them in decades. But if you’re looking at a skyscraper, driving a car, or even glancing at the aluminum foil in your kitchen, you’re looking at the ghost of this company’s influence. They were the invisible backbone of the 20th century.
It’s wild.
We tend to obsess over the tech giants of today—the Googles and the Apples—but Great Lakes Carbon was the "tech" of its era, specializing in the grit and heat of industrial production. They were once the world’s largest producer of calcined petroleum coke. That sounds boring. It sounds like something you’d skip over in a chemistry textbook. But without that specific material, the aluminum and steel industries would have basically ground to a halt.
The story of Great Lakes Carbon Company isn't just a corporate history; it’s a lesson in how a single, specialized commodity can move the needle on global economics. They weren't just making a product. They were fueling the infrastructure of the modern world.
The Skakel Dynasty and the Rise of an Empire
To understand Great Lakes Carbon Company, you have to understand the Skakel family. George Skakel started the company back in 1919. Think about that for a second. This was right after World War I, a time of massive industrial shift. Skakel wasn't some trust-fund kid; he was a powerhouse who saw a gap in the market for carbon products and drove a truck through it.
He built a dynasty.
The name Skakel might sound familiar for other reasons, too. George’s daughter, Ethel, famously married Robert F. Kennedy. This catapulted the family from "rich industrial owners" to "American royalty." It’s one of those weird intersections of heavy industry and high-stakes politics that you only really see in mid-century America. While the Kennedys were navigating the White House, the Skakels were navigating the global supply chain for petroleum coke and graphite electrodes.
The company grew like wildfire. By the middle of the century, they had plants scattered across the United States—places like Enid, Oklahoma; Port Arthur, Texas; and Niagara Falls. They weren't just a local player. They were an international force, with operations stretching into Europe and Asia.
What They Actually Made (And Why It Mattered)
Okay, let’s get into the weeds for a minute. What does a "carbon company" actually do?
Mostly, they dealt with petroleum coke.

When you refine crude oil, you get gasoline, diesel, and jet fuel. But at the bottom of the barrel, there’s this heavy, sludge-like byproduct. Through a process called "calcining"—which basically means heating the crap out of it in a rotary kiln at temperatures exceeding 2000 degrees Fahrenheit—Great Lakes Carbon turned that sludge into high-purity carbon.
- Aluminum Smelting: This is the big one. You need carbon anodes to smelt aluminum. No Great Lakes Carbon? No soda cans. No airplane wings. No lightweight engine blocks.
- Steel Production: They manufactured graphite electrodes. These are massive carbon rods used in electric arc furnaces to melt scrap steel. It’s a violent, high-energy process, and those electrodes have to be incredibly durable.
- Specialty Graphite: This went into everything from nuclear reactors to the nose cones of rockets.
It’s easy to overlook the "ingredients" of the world. We see the finished car, not the carbon electrode that helped forge its frame. Great Lakes Carbon lived in that invisible space. They were the masters of the "intermediate good."
The Pivot to SGL Carbon and the End of an Era
Nothing stays the same forever. By the late 1980s and early 90s, the industrial landscape was shifting. Globalization was kicking in. Environmental regulations were tightening (rightfully so, because carbon plants are notoriously dirty). The Skakel family eventually stepped back, and the company went through a series of massive structural changes.
In 1992, the graphite branch of Great Lakes Carbon merged with SIGRI GmbH (a subsidiary of Hoechst AG) to form SGL Carbon.
That was basically the end of the "Great Lakes Carbon" name as a standalone powerhouse. It was a massive consolidation. The move reflected a broader trend in the 90s: get big or get out. To compete on a global scale, you needed more than just American plants; you needed a unified European and American front.

SGL Carbon remains a massive player today, but the raw, family-owned grit of the original Great Lakes Carbon Company is a relic of a different time. It was a time when a few families controlled the literal building blocks of the nation. It was less about "apps" and "synergy" and more about heat, pressure, and raw materials.
The Environmental and Social Footprint
We can't talk about a massive carbon company without talking about the mess. Honestly, the legacy is complicated. Carbon plants aren't exactly eco-friendly parks. They involve massive amounts of dust, heat, and emissions. Over the years, the various iterations of the company faced scrutiny over air quality and worker safety.
And then there’s the Skakel family legacy itself, which became tabloid fodder. Most notably, the 1975 murder of Martha Moxley, which eventually led to the conviction (and later overturned conviction) of Michael Skakel, George’s grandson.
It’s a strange contrast. On one hand, you have this incredibly successful, vital business that literally helped build the 20th century. On the other, you have a family saga filled with tragedy, legal battles, and the kind of scrutiny that comes with extreme wealth and political ties. You can't really separate the company from the family that built it. They are intertwined in a way that modern corporations rarely are.
Why Should You Care Today?
You might think Great Lakes Carbon is just a footnote in a dusty business journal. But look at the current "Green Revolution."
Wait, what?
Yes, really. The irony is that the high-purity graphite and carbon products pioneered by companies like Great Lakes Carbon are now essential for the "clean" future. Graphite is a massive component in lithium-ion batteries. The anodes in your EV battery? They require the same kind of carbon expertise that George Skakel was honing back in the 1920s.
We are moving away from fossil fuels, but we are still incredibly dependent on the chemistry of carbon. The processes haven't changed that much; only the applications have. The technical knowledge developed in those old Great Lakes Carbon plants in Enid or Niagara Falls is the foundation for the battery plants of tomorrow.
Actionable Insights: Learning from the Carbon Giants
If you're a business owner or an investor, there are a few "real-world" takeaways from the rise and fall of this empire. It’s not just history; it’s a blueprint.

- Own the Bottleneck: Great Lakes Carbon didn't try to make everything. They focused on a specific, "must-have" ingredient for the world's most important industries (steel and aluminum). If you own the bottleneck, you own the market.
- Adapt to the "Bottom of the Barrel": They took a waste product (refinery sludge) and turned it into a high-value industrial necessity. There is almost always a way to monetize the "byproducts" of other industries.
- Watch the Consolidation Curves: The merger into SGL Carbon was a sign of the times. If you are in a capital-intensive industry, eventually, you will either have to merge to gain scale or be crushed by someone who did.
- Legacy is Double-Edged: High-profile leadership can bring doors open (the RFK connection), but it also brings a level of scrutiny that can distract from the core mission. Private companies often thrive in the shadows; Great Lakes Carbon found out what happens when the shadows disappear.
The Great Lakes Carbon Company is a ghost now, absorbed into global conglomerates and obscured by family drama. But every time you see a jet take off or a skyscraper catch the light, remember that it took a lot of heat, a lot of pressure, and a whole lot of carbon to make that happen.
If you want to understand where we're going with battery tech and green energy, start by looking at where we've been. Look at the carbon.
