Who Is Joanna Sturm?

Joanna Sturm sits at the intersection of American political history, personal tragedy, intellectual legacy, and active conservation. She is not a celebrity in the modern sense of the word. She does not pursue fame, maintain a social media presence, or seek public attention. 

What she does instead is something far more lasting: she serves as the living guardian of one of the most significant presidential legacies in United States history.

As the great-granddaughter of President Theodore Roosevelt and the granddaughter of Alice Roosevelt Longworth, arguably the most socially powerful woman in twentieth-century Washington, Joanna grew up surrounded by presidents, senators, diplomats, and the raw machinery of American political life. 

She sat at Alice’s famous dinner table at the Dupont Circle home, where guests included Presidents Kennedy, Johnson, and Nixon, alongside political figures like Henry Kissinger. That upbringing shaped everything that followed.

Joanna Sturm’s Family Background: The Roosevelt Connection

To understand Joanna Sturm fully, you need to understand the extraordinary family tree she carries.

President Theodore Roosevelt

Theodore Roosevelt, the 26th President of the United States, served from 1901 to 1909. He remains one of the most celebrated figures in American history, known for his conservation efforts, trust-busting policies, the construction of the Panama Canal, and the Nobel Peace Prize he won in 1906. His energy, intellectual curiosity, and fierce love of the natural world run like a thread through every generation that followed him, including Joanna Sturm herself.

Alice Roosevelt Longworth

Alice Lee Roosevelt Longworth was Theodore Roosevelt’s eldest daughter and the most publicly prominent member of the Roosevelt family for the better part of a century. Born on February 12, 1884, she lived until February 20, 1980, dying just eight days after her 96th birthday. 

During her lifetime, Alice met sixteen sitting U.S. presidents. She was renowned for her sharp wit, her fierce political opinions, and her ability to make and unmake political reputations with a single cutting remark. Washington insiders called her “the other Washington Monument.”

Alice’s marriage to Ohio Congressman and House Speaker Nicholas Longworth produced one daughter, Paulina, though Alice’s diaries confirm that Senator William Borah of Idaho was Paulina’s biological father. 

Alice reportedly acknowledged this by proposing the name “Deborah” for her daughter, a subtle nod to “de Borah,” before settling on Paulina after her husband refused.

Paulina Longworth Sturm

Paulina Longworth Sturm (February 14, 1925 – January 27, 1957) was Joanna’s mother and Alice’s only child. Biographers describe Paulina as an intensely private, deeply shy woman who struggled significantly under the enormous public shadow of her formidable mother. 

Her legal father, Nicholas Longworth, died when she was just six years old. Her relationship with Alice remained strained and emotionally complicated throughout her life.

In 1944, at nineteen years old, Paulina married Alexander McCormick “Sandy” Sturm, an artist, writer, and recent Yale graduate. 

Sandy came from a prominent family and co-founded Sturm, Ruger and Company, the American firearms manufacturer, alongside William Ruger. Together, Paulina and Sandy welcomed their daughter Joanna on July 9, 1946.

Tragedy struck on November 13, 1951, when Sandy died of hepatitis at just 28 years old. His death plunged Paulina into a severe depression that she never fully recovered from. 

She converted to Catholicism and sought spiritual meaning through social work, joining Dorothy Day’s Chrystie Street hospitality house in New York’s Lower East Side. On January 27, 1957, Paulina died of an accidental overdose of sleeping pills. She was 31 years old. Joanna was ten years old when her mother died.

Joanna Sturm Growing Up with Alice Roosevelt

Following Paulina’s death, Alice Roosevelt Longworth fought for and won full custody of her granddaughter, Joanna. The judge awarded guardianship to Alice, and Joanna moved into Alice’s famous Dupont Circle home in Washington, D.C., where she would stay for the next twenty-five years.

The relationship between Alice and Joanna stood in sharp contrast to the difficult bond Alice shared with her daughter, Paulina. Alice doted on Joanna completely. She described their bond as built from “twin cables of devotion and a healthy respect for each other’s tongue. 

” A 1969 American Heritage article called Joanna “a highly attractive and intellectual twenty-two-year-old” and named her “a notable contributor to Mrs. Longworth’s youthfulness.”

Friends who witnessed their relationship observed that Alice functioned as both father and mother to Joanna. The two discussed philosophy, poetry, Roman Catholic theology, horsemanship, and politics with equal ease. 

Joanna gave Alice intellectual companionship that kept her mentally sharp into her final decade, and Alice gave Joanna the stability, identity, and family she had lost with both her parents.

Vice President Richard Nixon served as a pallbearer at Paulina’s funeral in 1957, a fact that illustrates precisely how deeply embedded the family was in the highest levels of American political life.

Joanna Sturm’s Education

Joanna received her education in accordance with her mother, Paulina’s, Catholic faith. She attended Stone Ridge, the Sacred Heart day school in Bethesda, Maryland, where she graduated in 1963. 

She then enrolled at Newton College of the Sacred Heart in Newton, Massachusetts. After completing her undergraduate studies, she pursued graduate work at Georgetown University in Washington, D.C.

Her academic background in history and the humanities equipped her perfectly for the role she would later play as the primary living resource for Roosevelt family biographers and historians across five decades.

Joanna Sturm as Historian and Legacy Guardian

Joanna Sturm became one of the most important private historical resources in twentieth-century American biography. Over the past fifty years, scholars, journalists, and biographers writing about Theodore Roosevelt and Alice Roosevelt Longworth have consistently relied on her as a cited primary source.

At least twenty major books about Theodore Roosevelt and his children appeared in the past thirty years alone. At least six of those focused specifically on Alice Roosevelt Longworth. Joanna appears as a credited resource in virtually every significant work among them.

Her most important contribution to American historical preservation came through two oral history recordings she personally made of her grandmother Alice, recordings that she donated to the Library of Congress. These recordings preserve Alice Roosevelt Longworth’s voice, memories, and opinions for permanent public access, ensuring that a woman who knew sixteen presidents firsthand can still speak to future generations.

Joanna also accompanied her grandmother to both of Alice’s famous television appearances: her landmark 60 Minutes interview in 1969, when Alice was 85, and her follow-up appearance in 1974. These interviews marked the first time Alice Roosevelt Longworth appeared on American television, and Joanna was present at both.

In 2007, Joanna provided access to Alice’s private diaries to biographer Dr. Stacy A. Cordery, who used them to write her biography Alice: Alice Roosevelt Longworth, from White House Princess to Washington Power Broker. That book became the definitive account of Alice’s life, and it would not have been possible without Joanna’s cooperation and access.

Alice Roosevelt Sturm: Joanna’s Daughter

Joanna Sturm had a long-term relationship with Robert J. Hellman, PhD. (April 19, 1945 – March 9, 2008). Together, they welcomed a daughter, Alice Roosevelt Sturm, born on June 26, 1987. 

The name Alice Roosevelt Sturm carries the full weight of the family legacy intentionally, connecting the next generation directly to the great-grandmother who raised Joanna and to the great-great-grandfather Theodore Roosevelt himself.

Joanna brought young Alice to the Hat Ranch in Arizona when Alice was just one year old, beginning a decades-long family connection to the property that would eventually lead to one of Joanna’s most significant philanthropic acts.

Joanna Sturm Today: Conservation Philanthropy and the Hat Ranch

In April 2021, Joanna Sturm made the most public and consequential act of her philanthropic life. She provided the financial gift that allowed Northern Arizona University to purchase the historic Hat Ranch, a 300-acre property near Williams, Arizona. The donation established the Joanna Sturm Conservation Fund at NAU, which permanently protected the ranch from commercial development and large-scale cattle grazing.

The Hat Ranch carries its own extraordinary historical legacy. Isabella Greenway, Arizona’s first congresswoman and a close friend of Eleanor Roosevelt, built the ranch in 1928. Franklin D. Roosevelt visited it during his 1932 presidential campaign. 

Eleanor Roosevelt sent her two sons to work as summer cowhands there. In 1963, a sixteen-year-old George W. Bush worked his very first job at Hat Ranch, a story Joanna shared publicly during the donation announcement.

NAU now uses Hat Ranch for summer environmental science field courses, ecology and astronomy research, and conservation education programs. 

The ranch’s mission of connecting people to the Colorado Plateau’s natural world directly honors Theodore Roosevelt’s foundational commitment to American conservation.

“I would hope that it would be promoting research, conservation, and climate change solutions,” Joanna said during the donation announcement. “And I hope there’ll be a lot of birds there.”

As of 2026, She lives privately in Washington, D.C., approximately one mile from Alice Roosevelt Longworth’s former home. 

Her Washington residence holds Alice’s original oak dining table, a narwhal tusk likely given to Alice as a wedding gift, and numerous other family memorabilia. She continues to support conservation organizations, including the Grand Canyon Trust.

Joanna Sturm Net Worth

Joanna Sturm’s net worth is estimated between $5 million and $10 million. This estimate reflects her inherited family assets, the considerable financial capacity required to fund the Hat Ranch donation to NAU in 2021, and her long-term philanthropic activity. 

She has never publicly disclosed her financial details, and as a private individual, no verified net worth figure exists. Her connection to the Sturm, Ruger and Company fortune through her father’s legacy represents a potential historical component of her family’s financial background.

Little-Known Facts About Joanna Sturm

She lived with her grandmother for twenty-five years. After moving into Alice’s Dupont Circle home at age ten, Joanna stayed there until her mid-thirties. That home shaped her entirely.

She personally preserved Alice’s voice for the Library of Congress. Joanna recorded two oral history sessions with Alice Roosevelt Longworth that now sit permanently in the Library of Congress archives. Without her effort, those recordings would not exist.

Her biological grandfather was a U.S. Senator. Alice Roosevelt’s private diaries confirm that Senator William Borah of Idaho was the biological father of Paulina, making him Joanna’s biological grandfather rather than Nicholas Longworth, the legal grandfather.

George W. Bush held his first job at the ranch she donated. The Hat Ranch that Joanna donated to NAU in 2021 was the site of a sixteen-year-old George W. Bush’s very first job, a fact Joanna herself recounted during the donation announcement.

Her daughter carries Alice Roosevelt’s name directly. By naming her daughter Alice Roosevelt Sturm, Joanna ensured that the most celebrated name in her family’s history continues into the next generation as a living identity rather than just a historical record.

She kept Alice’s dining table. Joanna still owns the oak dining table at which Alice Roosevelt Longworth entertained presidents, senators, and diplomats for decades. It sits in Joanna’s own Washington home today.
