Nobel chemistry laureate Omar Yaghi was born to Palestinian refugees in Jordan, a quiet, studious child in a "large, rowdy family" that shared a single room with cattle they raised.
Which made Wednesday's news that the chemist at the University of California, Berkeley was among 2025's class of Nobel winners all the more emotional, Yaghi told journalists.
He described how his parents spent "every minute of their time dedicated to their kids and to their kids' education, because they saw that as a way to lift themselves and the kids out of challenging situations."
Their home had no electricity or running water. His father had finished school through sixth grade and his mother could neither read nor write.
"We didn't have a lot of the conveniences that many others do, but we had a lot of love and a lot of care," the scientist said.
Yaghi won the 2025 prize together with Susumu Kitagawa of Japan and UK-born Richard Robson for their groundbreaking discoveries on metal–organic frameworks (MOFs), whose uses include capturing carbon dioxide and harvesting water from desert air.
Born in 1965, he spent his childhood in Amman, Jordan, before leaving for the United States at the age of 15, on the advice of his stern father who saw for his son an opportunity to thrive.
At that point young Yaghi had already grown enamored with molecular structures after being drawn to "unintelligible but captivating" images in a book.
"I fell in love with them, even before I knew they were molecules," Yaghi said.
'Equalising force' of science
He began at a community college in upstate New York before transferring and finishing a degree at the State University of New York at Albany, supporting himself by bagging groceries and mopping floors.
Yaghi completed his PhD at the University of Illinois at Urbana-Champaign in 1990 and went on to work at a number of US universities before landing at UC Berkeley in 2012.
Yaghi was en route to Brussels via Frankfurt for a chemistry conference when the Nobel organisers got in touch with him with news of his prestigious honor, which he said "surprised and delighted" him.
"You cannot prepare for a moment like that," he said.
Yaghi's accomplishments include leading a research group that extracted water from desert air in Arizona, work his students have told him has garnered more than 250,000 citations.
The child of refugees told the Nobel Foundation Wednesday that "science is the great equalising force in the world."
"Smart people, talented people, skilled people exist everywhere," Yaghi said.
"That's why we really should focus on unleashing their potential through providing them with opportunity."
