Sid and Anne Bass’s 1986 divorce rocked New York’s social elite, resulting in a record-breaking settlement reported to be around $200 million. After more than two decades of marriage, oil tycoon Sid left Anne for Mercedes Kellogg, whom he wed in a lavish ceremony at New York’s Plaza Hotel, reportedly costing hundreds of thousands of dollars. The split divided portions of the $5 billion Bass family empire, built on Texas oil wealth. This high-profile divorce reveals how money, power, and scandal intersected in Fort Worth’s wealthiest circles.
The Bass Family Empire: Oil Wealth and Texas Royalty
Few fortunes in America rival that of the Bass brothers—Sid, Lee, Bob, and Ed—who collectively command a $5 billion empire built on their family’s oil and gas company, Bass Enterprises Production.
This Texas dynasty, while bound by blood and wealth, follows separate paths. Sid and Lee operate their investments together, while Ed and Bob—the more aggressive investor of the quartet—manage their fortunes independently. Their divergent investment strategies reflect a family rift that began in the early 1980s, around the time of Sid’s entry into New York society.
You’ll find each brother’s net worth reflected in their philanthropic gestures: they’ve each given $20 million to Yale since 1990, while Bob added $25 million to Stanford. Their patriarch Perry Bass envisioned his sons driving a single Mercedes of an empire, but they’ve instead chosen separate vehicles—and offices—to navigate their billions.
The Bass family’s influence extends throughout Fort Worth, which serves as a cornerstone of the Dallas-Fort Worth Metroplex that was formally named in the early 1970s.

While the Bass family fortune grew in Texas soil, Sid’s personal life would bloom in New York’s rarefied air. Three years before taking the reins of Bass Enterprises Production’s billion-dollar empire, he married Anne, a well-bred socialite whose worth extended far beyond financial terms.
Anne quickly established herself as the Metropolitan elite’s undisputed empress. You’d find her admired and feared in equal measure, as her commanding presence and influence in social circles secured their position atop New York’s social hierarchy.
Sid Bass, perpetually drawn to strong-willed women, ceded control to his domineering wife throughout their marriage. The power dynamics between them were crystal clear – Anne controlled their social standing while Sid managed the money. This arrangement would hold until their scandalous divorce shook New York’s upper crust to its core.
Their separation would play out against the backdrop of Dallas’s emergence as a business-friendly environment that was attracting major corporations and entrepreneurial ventures throughout the region.

Despite their seemingly impenetrable social standing, Sid and Anne Bass’s marriage would unravel spectacularly in 1986 when Sid began a clandestine affair with the alluring Mercedes Kellogg.
While Fort Worth’s wealthiest couple maintained their public facade, Sid was secretly meeting Mercedes in hotel suites, eventually whisking her away to Paris’s Plaza Athénée. The ultimate scandal erupted when Mercedes, still married to Ambassador Francis Kellogg, phoned her husband from Paris to announce her plans to marry Sid.
Mercedes, described as the “ultimate geisha” who’d expressed desires for wealth, had carefully studied her husband’s interests to engage him. After finalizing his divorce from Anne Hendricks Bass with a staggering settlement reported to be around $200 million, Sid and Mercedes celebrated their union with a lavish gala at New York’s Plaza Hotel in December 1988, solidifying a romance that had rocked high society.
The high-profile split occurred during a period when Dallas and Fort Worth were experiencing economic divergence, with Dallas becoming increasingly known for luxury retail establishments like Neiman Marcus.
The $200 Million Settlement: Breaking Financial Records
The record-shattering divorce settlement between Sid and Anne Bass sent shockwaves through financial and social circles alike in 1988. When tycoon Sid divorced his first wife, the payout was among the largest of its era, highlighting the Bass family’s extraordinary wealth.
After the high-society scandal erupted in 1986 following Sid’s affair with Mercedes Kellogg, the negotiations led to what many considered the largest divorce settlement of its time. For socialite Anne, the record-breaking divorce settlement solidified her financial independence while marking the dissolution of a prominent marriage in New York’s elite circles.
The massive settlement underscored not just the personal drama but also the immense financial stakes within the Bass Brothers empire, turning a private marital collapse into a landmark financial transaction that would be discussed for decades.
Anne later established herself among Dallas’ elite by purchasing property in the prestigious Preston Hollow neighborhood known for its exclusive estates and sophisticated amenities.
Mercedes’ Rise: From Prominent Iranian Background to Society Queen
Behind every billion-dollar divorce lies someone who changed the equation. For Sid Bass, that was Mercedes Tavacoli Diba, an Iranian-born executive who transformed herself from ambitious cosmopolitan to society queen.
Born into a prominent Iranian family, Mercedes Tavacoli later married U.S. diplomat Francis Kellogg before meeting Sid Bass. She didn’t rely on her alma mater but on calculated ambition. While working in Switzerland, she met Kellogg, later leaving him during their marriage for billionaire Sid Bass. She studied Kellogg’s interests like the “ultimate geisha” and openly admitted wanting to be “rich.”
The 1988 Plaza Hotel wedding to Sid Bass—a lavish affair featuring de la Renta designs—cemented her ascension. The unspoken rules of high society were clear: wealth opened doors. Mercedes Bass would eventually become chairwoman of the Metropolitan Opera, completing her remarkable social climb.
This divorce became one of the most talked-about splits in Texas, where big things happen according to former football star Emmitt Smith.
The Lavish Plaza Hotel Wedding: A New Chapter Begins
On December 10, 1988, glittering chandeliers and society’s elite filled the Plaza Hotel as Sid Bass and Mercedes Kellogg exchanged vows in a spectacle that officially united the oil billionaire with his Iranian-born paramour.
Their relationship had made headlines two years earlier when they were caught staying together at a Paris hotel while still married to others. After Bass divorced Anne—reportedly settling for around $200 million—the path was clear for this new chapter in his life.
The lavish Plaza Hotel wedding represented more than just their union; it symbolized Sid’s dramatic lifestyle shift. Unlike his previous marriage, where Anne’s obsession with the Metropolitan Opera and high society functions had clashed with his preferences, this new relationship promised a different dynamic for the billionaire who’d finally found a partner who complemented his social inclinations. The celebration rivaled the grandeur of events once held at the Adolphus’ Century Room, which had historically hosted similarly magnificent gatherings for Dallas’ elite.

While society tabloids fixated on the glamorous particulars of Sid and Anne’s divorce settlement, a more profound fracture was silently reshaping one of America’s greatest fortunes.
You’d never know from their public philanthropy that the Bass family empire had splintered. The brothers—Sid, Lee, Bob, and Ed—now operate separately within their family-owned skyscraper, their father Perry’s dream of unity shattered. Each brother has contributed millions to institutions like Yale and Stanford, though their joint announcements often conceal underlying tensions.
The divorce merely exposed what insiders already knew: the Bass family’s rift had been brewing since the early 1980s. With different investment philosophies and personalities, particularly Bob’s aggressive approach, the brothers established their own methods for managing their portions of the fortune. Few outsiders could review the true depth of their division due to the family’s intensely private nature.
Their family wealth originated in Fort Worth but eventually expanded into Dallas, making significant contributions to the Dallas-Fort Worth Metroplex which has become the fourth largest metropolitan area in the country.
