The Immigrant Who Built Half of America's Libraries

Between 1883 and 1929, one man funded the construction of 2,509 libraries across the English-speaking world. By the time he stopped, Andrew Carnegie had paid for nearly half of all libraries in the United States. The Scottish immigrant who arrived in Pennsylvania as a poor teenager would become the architect of American public knowledge—quite literally, since his foundation eventually started dictating how the buildings should be designed.

But Carnegie's library philanthropy wasn't simply about generosity. It was a calculated philosophy about who deserves help and how they should receive it. His approach would revolutionize how libraries operated, spark controversy about wealth and obligation, and leave behind buildings that still stand in thousands of communities today.

From Borrowed Books to Billions

To understand why Carnegie built libraries, you need to understand where he came from.

Andrew Carnegie was born in Dunfermline, Scotland, in 1835. His family emigrated to America when he was thirteen, settling in Allegheny, Pennsylvania—now part of Pittsburgh's North Side. As a teenager working for the local telegraph company, Carnegie had no access to formal education. What he had was Colonel James Anderson.

Anderson was a local businessman who opened his personal book collection to working boys every Saturday. Carnegie would later write in his autobiography about how Anderson provided an opportunity for "working boys"—young men that some people said should not be "entitled to books"—to acquire the knowledge they needed to improve themselves.

This experience shaped Carnegie's entire worldview. He believed in merit. He believed that anyone who worked hard could become successful. And he believed that the role of the wealthy was not to give handouts, but to create opportunities for those "industrious and ambitious" enough to seize them.

Carnegie's first library was personal: in 1880, he commissioned a public library in his birthplace of Dunfermline. It opened in 1883. His second was in Allegheny, commissioned in 1886 and opened in 1890. His third was in Braddock, Pennsylvania, about nine miles up the Monongahela River from Pittsburgh—and conveniently, the site of one of Carnegie Steel Company's mills.

Notice the pattern. Carnegie wasn't yet a philanthropist with a grand vision. He was a successful businessman honoring the places that had shaped him.

The Carnegie Formula

Everything changed in 1897 when Carnegie hired James Bertram as his personal assistant.

Bertram transformed Carnegie's sporadic generosity into a systematic operation. When a town wanted a Carnegie library, Bertram sent them a questionnaire. How large was the population? Did they already have a library? How many books? What were the circulation figures? And crucially: how much was the town willing to pledge for annual maintenance?

This last question was the key to what became known as "the Carnegie formula."

Carnegie didn't simply give towns money for buildings. He required them to demonstrate need, provide the building site, and commit to funding operations entirely through public taxation—not private donations. Specifically, the town had to pledge at least ten percent of the construction cost annually for staff, books, and maintenance.

Why such strict requirements? Carnegie explained his reasoning bluntly:

An endowed institution is liable to become the prey of a clique. The public ceases to take interest in it, or, rather, never acquires interest in it. The rule has been violated which requires the recipients to help themselves. Everything has been done for the community instead of its being only helped to help itself.

This was Carnegie's philosophy distilled to its essence. He would help people help themselves. Nothing more.

The Women Who Actually Built the Libraries

Here's something the standard Carnegie story often overlooks: the buildings didn't materialize simply because Carnegie offered money.

Beginning in 1899, Carnegie's foundation funded a dramatic increase in library construction. This timing was not coincidental. It aligned precisely with the rise of women's clubs in post-Civil War America. These organizations—often the only civic groups women could join—took the lead in establishing libraries across the country.

The women did the unglamorous work. They organized long-term fundraising campaigns. They lobbied their communities to support library operations. They convinced skeptical town councils to commit public funds. By some estimates, women's clubs led the establishment of seventy-five to eighty percent of libraries in communities across America.

Carnegie provided the capital. The women provided everything else.

Separate Libraries for a Segregated Nation

Carnegie's belief in merit had a glaring blind spot: race.

Under segregation, Black Americans were systematically denied access to public libraries throughout the Southern United States. Carnegie faced a choice. He could have insisted that any library bearing his name serve all citizens equally. He did not.

Instead, Carnegie funded separate libraries for African Americans. In Houston, he paid for a "Colored Carnegie Library." In Savannah, Georgia, he funded a library that opened in 1914 specifically to serve Black residents who had been excluded from the segregated white public library.

The Savannah case reveals how the Carnegie formula intersected with Jim Crow. A group called the Colored Library Association of Savannah had raised money and collected books to establish a small "Library for Colored Citizens." By demonstrating their willingness to support a library—by helping themselves, in Carnegie's terms—they qualified for his funding.

One of the children who used that Savannah library was Clarence Thomas, who would grow up to become a United States Supreme Court Justice. In his 2008 memoirs, Thomas wrote about frequently visiting the Carnegie library as a boy, before the public library system was desegregated.

Carnegie's accommodation of segregation raises uncomfortable questions. Did his libraries advance opportunity for Black Americans, or did they legitimize a system designed to deny it? The answer is probably both.

How Carnegie Changed Library Design Forever

If you've ever wandered through a library, browsing shelves and pulling down whatever catches your eye, you're experiencing Andrew Carnegie's most revolutionary contribution to library science.

Before Carnegie, libraries operated on what was called a "closed stacks" policy. You couldn't browse. You approached a desk, requested a specific book, and a library staffer retrieved it from stacks that were off-limits to the public. This was the standard practice everywhere.

Carnegie changed it.

To reduce operating costs—remember, towns had to fund ongoing operations—Carnegie created what he called "open-shelf" or "self-service" access. Beginning with the Pittsburgh neighborhood branches that opened after the main library, patrons could walk directly into the stacks and choose their own books.

This seems obvious now. At the time, it was revolutionary. And it created a design problem: theft.

Carnegie's architects solved this by placing massive circulation desks just inside the front door. These desks were far larger than anything in modern libraries, spanning almost the entire width of the lobby. They served as both physical and psychological barriers between the entrance and the books.

The first "open stack" Carnegie library was the Lawrenceville branch in Pittsburgh, the sixth Carnegie library to open in America. Its design became the template for thousands of others. The stacks were arranged in a radial pattern so librarians could see down every aisle. Walls became glass partitions above waist level. And for the first time in any library anywhere, there was a dedicated room for children.

As architectural historian Walter Langsam later wrote: "The Carnegie libraries were important because they had open stacks which encouraged people to browse. People could choose for themselves what books they wanted to read."

The Buildings Themselves

Carnegie libraries were built in a remarkable variety of architectural styles: Beaux-Arts, Italian Renaissance, Baroque, Classical Revival, Spanish Colonial, and in Scotland, Scottish Baronial. Each community could choose its own style.

But certain elements appeared almost universally.

Nearly every Carnegie library featured a prominent doorway accessed by a staircase from ground level. This wasn't just practical—it was symbolic. The entry staircase represented a person's elevation through learning. You literally climbed toward knowledge.

Most libraries also featured a lamp post or lantern near the entrance, symbolizing enlightenment.

As the years passed, Bertram grew increasingly particular about design. He developed detailed architectural criteria: lecture rooms, separate reading rooms for adults and children, staff rooms, centrally located librarian desks, ceilings twelve to fifteen feet high, and large windows positioned six to seven feet above the floor to maximize wall space for books below.

Fireplaces were discouraged. Not because they weren't pleasant, but because fireplace walls could hold more shelves.

Interestingly, there was no requirement to put Andrew Carnegie's name on the building. Many communities did anyway.

The Critics

Not everyone celebrated Carnegie's generosity.

Alice S. Taylor, the first secretary of the Iowa Library Commission, criticized communities for using Carnegie funding to build extravagant buildings rather than focusing on quality library services. Carnegie's money covered only construction. The books, the staff, the ongoing operations—those were the town's problem.

Small communities often struggled. Towns were happy to accept funding for impressive new buildings, but reluctant to allocate taxes for upkeep. The most frequent criticism of Carnegie libraries in hindsight is that gifting libraries to towns too small to support them actually slowed the development of cooperative regional library systems that those communities eventually came to rely on.

Other critics saw his donations as insulting—an implication that communities couldn't fund their own public works. Some viewed his push for public libraries as an attempt at social control, getting to decide what knowledge the masses could access.

Mark Twain, who generally supported Carnegie, nonetheless claimed he used philanthropy as a tool to buy fame.

The harshest criticism came from those who questioned whether philanthropy could ever offset how the wealth was accumulated in the first place. William Jewett Tucker argued from a religious viewpoint that Carnegie's contributions did not justify the "evils" of capitalism that had made them possible.

Carnegie's own steel workers had the most pointed response. They argued that his wealth would be better distributed as fair wages than as gifts from above. The Homestead Strike of 1892, in which Carnegie's company violently suppressed a labor dispute, cast a long shadow over his philanthropic reputation.

The Numbers

The scale of Carnegie's library philanthropy is difficult to comprehend.

Almost fifty-six million dollars went for construction of 2,509 libraries worldwide. Of that, forty million dollars funded 1,670 public library buildings in 1,412 American communities. Another 660 libraries were built in the United Kingdom and Ireland, 125 in Canada, and dozens more scattered across Australia, South Africa, New Zealand, Serbia, Belgium, France, the Caribbean, Mauritius, Malaysia, and Fiji.

Small towns received grants of around ten thousand dollars—a massive sum in that era—enabling them to build libraries that immediately became among the most significant public amenities in their communities.

The timing mattered enormously. Carnegie's philanthropy coincided with a peak in new town development across America and a period when states were beginning to take active roles in organizing public libraries. His funding filled a tremendous need at precisely the moment when communities were ready to use it.

Carnegie continued funding new libraries until shortly before his death in 1919. By then, he had funded nearly half of all the libraries in the United States.

What Remains

Thousands of Carnegie library buildings still stand today, though many have been repurposed. Some remain active libraries. Others have become museums, community centers, offices, or private residences. A few have been demolished.

But Carnegie's most lasting contribution isn't architectural. It's philosophical.

The open-stack policy he pioneered became standard everywhere. The idea that libraries should be funded through public taxation rather than private endowment shaped how Americans think about civic institutions. The physical design elements he standardized—children's rooms, central circulation desks, reading rooms with natural light—influenced library architecture for generations.

Even the Carnegie formula itself, requiring communities to demonstrate commitment before receiving help, became a model for philanthropy more broadly. It's the intellectual ancestor of every matching grant and every challenge fund.

Carnegie believed that wealth created obligation. He believed the rich should use their fortunes to help others help themselves. And he believed that books—that knowledge itself—was the surest path to advancement for anyone willing to climb those symbolic stairs.

Whether that philosophy was noble or paternalistic, generous or controlling, probably depends on who you ask. But walk into nearly any American town of a certain age, and you'll likely find a handsome old building with high ceilings and large windows, perhaps with a lamp post near the door. Someone climbed those stairs once, pulled a book from an open shelf, and found something that changed their life.

That was always the idea.
