Behind the walls of 1600 Santa Barbara Street is the story of a woman who quietly helped change the course of the 20th century.
Katharine Dexter McCormick was an MIT-trained biologist, suffragist, philanthropist and the driving financial force behind the development of the birth control pill. For more than a decade, this remarkable Santa Barbara property was the place she called home.

A Life Shaped Early On
Katharine was born in 1875 in Dexter, Michigan, and raised in Chicago in a wealthy, well-connected family. But her early life was marked by loss. Her father died when she was 14, and not long after, her only brother contracted meningitis while attending Harvard and died.
Those experiences helped spark a fascination with the human body and medicine, and Katharine decided she wanted to pursue science — an ambitious choice for a woman in the 1890s.
She was admitted to MIT and graduated in 1904 with a degree in biology, becoming one of the first women to do so. While there, she wasn't afraid to challenge the establishment. In one now-famous example, she pushed back against rules requiring women to wear feathered hats in the laboratory, pointing out the obvious danger of combining feathers with open flames.
Her plan was to attend medical school next. Instead, she met Stanley McCormick, heir to the McCormick reaper fortune. The two married, and her life took an unexpected turn.

Marriage, Medicine & Advocacy
Just two years into their marriage, Stanley was diagnosed with schizophrenia and institutionalized. Katharine would spend decades advocating for a voice in decisions surrounding his treatment and estate, sometimes taking those battles to court.
Her scientific interests never disappeared. In 1927, she founded and funded the Neuroendocrine Research Foundation at Harvard Medical School, supporting research into possible treatments for Stanley's illness for the next twenty years.
At the same time, Katharine was becoming a formidable advocate for women.
She became deeply involved in the women's suffrage movement, served as an officer of the National American Woman Suffrage Association and later helped establish the League of Women Voters.
Her activism went even further.
During the 1920s, Katharine used trips to Europe to bring more than a thousand diaphragms into the United States for Margaret Sanger's birth control clinics — at a time when distributing contraception was illegal.
It was the beginning of a partnership that would eventually change women's lives around the world.

Funding the Birth Control Pill
Stanley died in 1947, leaving Katharine an estate of approximately $15 million and giving her full control of substantial financial resources.
Then, in 1953, Margaret Sanger introduced her to biologist Gregory Pincus, who was working on something revolutionary: a hormonal contraceptive pill.
The science showed promise. What the project lacked was money.
Katharine stepped in.
She became its primary financial backer, ultimately contributing roughly $2 million of her own money and remaining closely involved throughout its development.
In 1960, the FDA approved the birth control pill her funding had helped make possible — one of the most consequential medical developments of the twentieth century.
Her philanthropy also came full circle at MIT. She funded Stanley McCormick Hall, a women's dormitory that dramatically expanded the university's ability to house female students.
Her Final Years
Katharine died in Boston in 1967 at the age of 92.
Her will left $5 million to Planned Parenthood, which later established the Katharine Dexter McCormick Library in New York in her honor.
Despite the extraordinary scope of her life, her death received relatively little attention in the press. Only in more recent decades has her pivotal role in the development of the birth control pill — and the broader advancement of women — received greater recognition.
And that brings us back to Santa Barbara.
The House She Called Home
At 1600 Santa Barbara Street stands one of the remaining physical connections to Katharine's remarkable life.
Originally built in 1940 as a wellness facility and designed by noted Santa Barbara architect Chester Carjola, the property was later transformed into a private residence and became Katharine's Santa Barbara home.
Her relationship with the Santa Barbara Museum of Art extended well beyond the house. Katharine was a generous supporter of the Museum and funded the Stanley R. McCormick Gallery in honor of her husband.
Upon her death in 1967, Katharine bequeathed 1600 Santa Barbara Street to the Santa Barbara Museum of Art, along with important works from her personal art collection. The property would go on to serve the Museum and the Santa Barbara community for decades, eventually becoming the Ridley-Tree Education Center at McCormick House.
Today, the estate encompasses nearly 12,500 square feet on approximately .72 acres, with remarkable original spaces still intact, including its grand ballroom and historic living room.
After approximately 85 years without ever being sold, 1600 Santa Barbara Street is now under escrow and preparing for its next chapter.
It's difficult to imagine a more fitting legacy for a house once occupied by a woman who spent so much of her life challenging convention — and shaping what came next.
