After Daughter’s Brain Hemorrhage, Billionaire Bill Ackman Pledges $400 Million for Recovery Research
Ackman Oxman Institute to combine brain research, neurosurgery, rehabilitation, medical devices, artificial intelligence, and longevity work with a patient-focused model with “highly commercial instincts”.
A parent’s worst nightmare has become the catalyst for a bold and innovative effort to transform brain-injury care.
Billionaire investor Bill Ackman and his wife, Neri Oxman, have pledged $400 million to create a new research institute focused on brain research, recovery, rehabilitation, and technological innovation, following the recovery of Ackman’s daughter from a severe brain hemorrhage earlier this year
Ackman’s deeply personal account of his daughter Lucy’s survival, despite a grim prognosis and after an extraordinary delay in treatment, offers both a testament to exceptional medical care and a reminder of how much remains beyond modern medicine’s reach when it comes to traumatic brain injuries.
At midnight on February 6th, earlier this year, the doorbell to our apartment rang. The doorbell was followed by a pounding on the door. I answered the door and a security person in our building handed me his phone. It was my oldest daughter Eloise. She had found my 26-year-old…

In his X post, Ackman recounts how, in February, his 26-year-old daughter Lucy was found unconscious after a massive brain hemorrhage. More than 19 hours had apparently passed before emergency surgery, a delay which normally makes intervention unlikely. However, surgeons at Elmhurst Hospital performed a successful hemicraniectomy (a procedure in which a piece of the skull is removed to reduce the pressure from swollen brain tissue).
By about 2:30am with the results from a CAT scan, Lucy’s doctors had determined that she had a massive brain hemorrhage and would need an emergency hemicraniectomy to release the pressure on her brain and remove the blood from the hemorrhage. I called our wonderful friend and family doctor Eddie Fisher and explained what was going on.
He woke up Josh Bederson, Chairman of Neurosurgery at Mount Sinai, to find out more about Zach Hickman, the neurosurgeon on call that night. Dr. Bederson said Hickman was an excellent surgeon, which was comforting as we had no choice.
The surgery to save Lucy’s life began around 3:15am and finished around 5:30am. It was successful.
Lucy was later transferred to Mount Sinai for intensive treatment and rehabilitation. After weeks in a coma and initially being unable to breathe independently, walk, see, or speak, Lucy regained cognition and can walk short distances with assistance and has made progress toward speech.
Ackman credits her clinical teams, family, friends, and supporters, while expressing optimism that years of care, technological advances, and possibly brain-computer interfaces could help restore more function.
Motivated by her experience, Ackman and his wife are establishing the nonprofit Ackman Oxman Institute (AOI) in Manhattan. This non-profit center is intended to combine brain research, neurosurgery, rehabilitation, medical devices, artificial intelligence, and longevity work with a patient-focused model with “highly commercial instincts“.
While the AOI will be a non-profit, it will have highly commercial instincts. The AOI will have its own venture funding and will work to develop innovations to create companies that we will seed, assist, and spinout to ensure technologies, treatments, techniques, and drugs get to patients as promptly as possible.
On one 3.4 acre campus in what is still the greatest city in the world, we will do neurosurgery, neuroscience, rehabilitation, nutrition, BCI and device development, human trials, hyperbaric oxygen treatments, and life extension programs, and we will mandate and incentivize collaboration among the teams with no silos, politics, bureaucracy, or any other constraint that is inconsistent with the mission.
Mount Sinai will be an important partner and deservedly so, but it won’t be our only hospital or medical school partner as we don’t believe any institution has a monopoly on the best ideas or the best talent. We don’t believe in exclusive relationships because that is not in the best interest of patients.
Interestingly, Ackman notes the collapsing economic conditions in New York City as well as the deterioration in the academic environment at universities as contributing factors in the timing of this move. The billionaire investor believes that top medical researchers will be willing to work at the institute.
…The real estate needed for the project became available at a 70% discount. Universities, meanwhile, have become “a much less attractive place to work,” he wrote, citing campus politics, antisemitism and declining funding.
That claim fits into Ackman’s broader fight with elite universities. He helped lead the pressure campaign against former Harvard president Claudine Gay, criticized the university’s handling of antisemitism, attacked its DEI policies and later called for the ousting of several Harvard board members.
Ackman’s post didn’t mention data points about scientists leaving universities en masse. But his new institute is being structured around the idea that top researchers can be persuaded to leave, or at least work outside, the traditional university system.

Ackman stresses that AOI’s emphasis will be on patient care and recovery, not on academic papers.
He said the AOI would not be primarily focused on producing academic papers or winning scientific awards, but on developing treatments, devices and rehabilitation techniques that can reach patients more quickly.
“We will be laser-focused on cures, treatments, devices, rehabilitation and exercise equipment,” Ackman wrote, adding that the goal would be to accelerate the process “from idea to innovation to production to helping a patient.”
The power of a father’s love and care to save his daughter’s life, that led to the brilliant vision of the Ackman Oxman Institute, that will bring treatment, greater longevity, quality of life and cures to millions of others suffering from brain injuries and decline. https://t.co/eHGfle1GbH

I truly hope the Ackman Oxman Institute becomes the patient-centered hub of medical innovation that Ackman and his wife aspire to create.
Their daughter’s devastating brain hemorrhage may have led her parents to build the foundation that helps push brain-injury care beyond incremental rehabilitation and toward complete recovery…not only for her, but millions of others.
That prospect is especially meaningful for stroke survivors such as Legal Insurrection editor Mandy Nagy, whose family and friends continue to hope that emerging therapies and rehabilitation advances will one day expand the options available to her.
I wish Ackman all good success in the project, and will be keeping an eye out for updates.

Recovery care is critical but prevention and early intervention is the name of the game in brain injury.
That said, his approach will be interesting. Papers after the fact may be just as effective as before. They will take more time but have more data.
Mary Nagy came to mind when I first read Bill Ackman”s X post.
Mandy.
There are multiple billionaires around the world and quite a few in the
USA. We should be grateful The zillionaires like Bill Ackman, who see a problem, and in his case, a very personal and extreme problem and take a look at what they have, and ask: how can I help? What can I do?
When I see or read actions like these, I am constantly reminded of Andrew Carnegie who built almost 1700 community libraries and 100 academic libraries so everyone could access to books and learning and growth.
Too often, we forget that with great wealth comes great opportunity and so many Americans gave so much back to the rest of us. Unfortunately, too many of our youth do not understand that.
Prayers for Lucy and family.
May his new brain institute benefit his daughter and millions more.
Hey, recovered or not, she can still run for president. Or become a Senator who gets more sensible as the healing progresses.
A good friend of mine from my teenage years has had lightning strike against her, many times (long story. Will tell you later.).
But last year, she was supposed to be at her job as a teacher in Fort Bend County (TX) when she collapsed, due to a massive brain hemorrhage. She had the surgery and spent weeks in the hospital. Fortunately, her aunt, uncles and cousins all live in the Houston area and have pitched in for her long-term rehab and recovery. She had to sell her house and retire, though. Her daughter has had to deal with life as the child of a disabled mom.
She’s in a wheelchair nowadays. Her left side is paralyzed. She goes to PT often. Hopefully, there will be soon more done for patients like her.
If Bill Ackman finds trouble seeking the right place in NY for his institute, he can find a friendly environment here in Houston. We have the Texas Medical Center, the largest medical research facility in the world. He will find plenty of allies here.
And, I believe, my friend can afford some hope.
