Today I want to honour a true hero in medical history - Vivien Thomas.
Many people may not know his name, but families like mine will forever be grateful for his brilliance and courage.
Vivien Thomas was the pioneer behind the surgical procedures used to treat Tetralogy of Fallot (TOF) - a congenital heart condition that once meant very little hope for babies born with it. At a time when opportunities were limited and recognition was scarce, he worked tirelessly to develop the techniques that would go on to save thousands upon thousands of lives.
My son is a TOF baby.
And because of the procedures that began with Vivien Thomas’ groundbreaking work, my son is now well.
There are no words strong enough to express the gratitude I feel. What was once a frightening diagnosis is now a story of survival, strength, and hope - all because one man refused to give up on finding a solution.
Vivien Thomas may not have worn the title of surgeon at the time, but his hands, his mind, and his determination changed the world of heart surgery forever.
Today, I celebrate him.
Today, I honour him.
And today, I say thank you - from one grateful parent whose child is alive and thriving because of your legacy.
💙 Forever Thankful
Vivien Thomas was not a doctor.
He never went to medical school.
Yet he became one of the most important pioneers in heart surgery in the twentieth century.
He was born on August 29, 1910, in New Iberia, Louisiana. He grew up in Nashville, Tennessee. After high school, he enrolled at Tennessee Agricultural and Industrial College, now Tennessee State University. He wanted to become a doctor.
Then the stock market crash of 1929 destroyed his savings. He could not afford to continue school.
In 1930, he took a job at Vanderbilt University as a laboratory assistant to surgeon Alfred Blalock. He had no formal medical training. But he showed great skill and a sharp understanding of surgical research.
Over time, he became Blalock’s main research partner. He performed complex surgeries on animals and helped develop new knowledge about surgical shock.
In 1941, Blalock became Chief of Surgery at Johns Hopkins Hospital. He brought Thomas with him.
Even with his growing expertise, Thomas was listed as a technician. He was paid far less than white colleagues because of racial discrimination.
At Johns Hopkins, Blalock worked with pediatric heart doctor Helen Taussig. She was searching for a way to help babies born with tetralogy of Fallot, a heart defect that caused severe oxygen loss. People often called it blue baby syndrome.
In the laboratory, Thomas developed and refined a new operation. It connected the subclavian artery to the pulmonary artery to increase blood flow to the lungs.
The procedure became known as the Blalock Taussig shunt.
On November 29, 1944, Blalock performed the first surgery using this method on a 15 month old baby named Eileen Saxon at Johns Hopkins. Thomas stood behind him in the operating room. He guided the steps based on the work he had done in the lab.
The surgery was a major breakthrough. It helped launch the field of pediatric heart surgery.
But the procedure carried the names of Blalock and Taussig. Thomas’s role was not included, even though his laboratory work made it possible.
For decades, Thomas trained young surgeons at Johns Hopkins. Many of them later became leaders in heart surgery. They learned their skills from a man who never held a medical degree.
In 1971, Johns Hopkins named him Instructor of Surgery. In 1976, the university awarded him an honorary Doctor of Laws degree to honor his contributions.
Today, his portrait hangs at Johns Hopkins Hospital.
Vivien Thomas died in 1985 at age 75.
In 2004, his life was told in the HBO film Something the Lord Made. The film introduced his story to a wider audience.
Today he is remembered as a brilliant surgical researcher whose skill and creativity changed heart surgery forever.
His life also tells another story.
A story about talent that was overlooked.
About barriers placed in front of Black scientists and medical professionals.
And about a man who helped save countless children, even when the world did not fully see him.
