Who are the Russells based on? The Gilded Age merged two robber barons and one ballroom war

The Russells are a composite. George Russell (Morgan Spector) draws on two railroad rivals: Jay Gould, whom Fellowes has named as the inspiration on HBO's official podcast, and Cornelius "the Commodore" Vanderbilt, per FandomWire. Bertha Russell (Carrie Coon) is Alva Vanderbilt, and her season 1 ball is Alva's 1883 costume ball, lifted almost whole.

Season 4 premieres November 1 on HBO and HBO Max, and the official logline already sounds like a bill coming due: "Bertha Russell (Carrie Coon) changed Society at a cost."

The two robber barons inside George

Fellowes told The Hollywood Reporter that George is "in a way" based on Gould. The rest of the character is borrowed piece by piece:

• Jay Gould (1836–1892): The railroad magnate and financier gave George his ruthlessness and, according to The Direct, his warmth as a family man. Fellowes's own summary: "even the robber barons thought he was ruthless." The real Mrs. Astor kept Gould out of her Four Hundred, just as the show's Mrs. Astor keeps George at arm's length.
• Cornelius Vanderbilt: Gould's rival, who made his fortune in shipping and railroads. Season 1's third episode borrows an episode from the Commodore's life, and Fellowes has said that "trying to trick Commodore Vanderbilt was a serious mistake, and they paid."
• Henry Clay Frick: He isn't a model for George, but he supplied a scene. George nearly opening fire on striking workers in season 2, episode 6 comes from a real incident involving Frick and Andrew Carnegie.

Fellowes chose the composite on purpose. He explained at a Preservation Society of Newport County event why he didn't simply dramatize the Vanderbilts.

"You can't make them do things that they didn't do."

So George gets Gould's reputation without Gould's biography, and Fellowes gets to decide what he does. That freedom is how a man modeled on the era's most hated financier can also be the show's most devoted husband.

The ballroom war

Bertha's real-life counterpart was born Alva Erskine Smith and married William K. Vanderbilt in 1875. On March 26, 1883, she threw a costume ball to open her French château-style mansion at 660 Fifth Avenue, designed by Richard Morris Hunt, per the Museum of the City of New York. Here's what that night looked like:

• The guest list: Nearly 1,200 people, all in costume.
• The bill: About $250,000, roughly $6 million today, including $65,000 for champagne and $11,000 for flowers.
• The program: At 11:30 p.m., the hobby-horse quadrille opened the dancing, the first of five quadrilles performed by young society members down the grand staircase.

The famous part is the invitation that never arrived. Mrs. Astor's daughter Carrie was left off the list, and Alva supposedly said she couldn't invite Miss Astor because Mrs. Astor had never called on her. Mrs. Astor left her calling card at the Vanderbilt house, and the invitation came the next day.

The Gilded Age season 1 finale stages exactly that move, with Bertha holding Carrie Astor's invitation hostage until Mrs. Astor calls in person. Fellowes told Vanity Fair that when he read about Alva's ball, he decided he was "just going to lift the whole thing."

"I love the almost cynicism of that."

The catch is in the museum's own wording. MCNY calls the calling-card story an "apocryphal tale." The most historically faithful scene in The Gilded Age is a legend the historians themselves won't fully vouch for.

The divorce Alva had and Bertha hasn't

The Vanderbilt blueprint keeps running past the ballroom. Gladys Russell's arranged marriage to a duke draws on Consuelo Vanderbilt, Alva's daughter, who was married off to the 9th Duke of Marlborough. Alva's own marriage to William K. Vanderbilt ended in divorce, and she went on to marry Oliver Belmont.

The show hasn't gone there yet, though it's getting close. In the last seconds of the season 3 finale, George walks out on Bertha. They aren't divorced, and Spector told TV Insider the Russells are trying to find their way back to each other.

"We haven't followed the [Vanderbilt] storyline yet, not to a T, so I'm hopeful."

Season 4 also casts Neal Huff as John D. Rockefeller, so the show that built George out of two robber barons will finally put a real one on screen under his own name. Fellowes invented the Russells so he wouldn't have to follow the Vanderbilts' history, and the one chapter of Alva's life Bertha hasn't lived yet is the divorce.
