Ada Yonath, born in 1939, is an Israeli crystallographer known for her pioneering work on the structure of ribosomes. She was awarded the Nobel Prize in Chemistry in 2009 for her contributions to understanding the ribosome's structure and function. Yonath's research has not only advanced our knowledge of fundamental biology but also opened up new possibilities for developing antibiotics that target bacterial ribosomes. She is a trailblazer in the field of structural biology and continues to inspire future generations of scientists.
