Core Event
Renowned structural biologist Ada Yonath, the 2009 Nobel laureate in Chemistry, passed away at the age of 87. Yonath spent her career at the Weizmann Institute of Science in Rehovot, where she led the Ribosome Group and held the Institute’s highest academic rank, “Institute Professor.” Her death marks the loss of one of Israel’s most internationally celebrated scientists.
Background & Context
Born in Jerusalem in 1939 to Polish-immigrant parents, Yonath pursued chemistry at the Hebrew University of Jerusalem (B.Sc. 1962, M.Sc. 1964) and earned a Ph.D. in X-ray crystallography from the Weizmann Institute in 1968. After post-doctoral work in the United States, she founded Israel’s first protein crystallography laboratory at the Institute in 1970. At a time when many scientists believed the ribosome—a massive RNA-protein complex responsible for protein synthesis—could not be crystallized, Yonath persisted, conducting roughly 25,000 experiments before obtaining the first ribosome crystals in 1980. Over the next two decades she refined cryo-bio-crystallography techniques and, in collaboration with the Max Planck Institute, mapped the three-dimensional structures of bacterial ribosomal subunits in 2000—a discovery later highlighted by *Science* as one of that year’s top ten scientific achievements.

Verbatim Quotes
- “Ada was an extraordinary scientist who was not afraid to choose a path that others thought impossible and pursue it with determination, curiosity and courage for decades,” — Prof. Alon Chen, weizmann institute president
- “Her breakthrough in ribosome research changed our understanding of one of the most fundamental processes of life and opened new possibilities for combating antibiotic resistance.” — Prof. Alon Chen, weizmann institute president
Why It Matters
Yonath’s elucidation of ribosomal structure clarified how antibiotics bind to bacterial ribosomes and inhibit protein production. This insight has guided the design of new drugs aimed at overcoming antibiotic-resistant bacteria, a pressing 21st-century health challenge. Beyond her scientific contributions, Yonath’s career demonstrated that persistent inquiry can overturn prevailing assumptions, inspiring generations of researchers worldwide.
Legacy & Personal Notes
Yonath’s personal story—rising from a modest family, supporting herself after her father’s early death, and balancing a demanding scientific career with motherhood—has been highlighted by colleagues as a testament to resilience. She is survived by her daughter, Dr. Hagit Yonath, director of an internal-medicine department at Sheba Medical Center, and her granddaughter, Noa, who once presented her with a “World’s Best Grandma” certificate.
