Ada Yonath
Ada Yonath is an Israeli chemist who made pictures of ribosomes using X-ray Crystallography. Ribosomes are the part of cells in the human body that put together proteins. X-ray Crystallography makes pictures of molecules by bunching them into crystals. This method is only used to make models of single atoms. Yonath used this methods to crystallize ribosomes although they are made of many atoms and proteins. This made her work very difficult. She returned to the Weizmann Institute of Science in 1970. She started the first Protein Crystallography lab in Israel. She did research at the Max Planck Institute for Molecular Genetics in Berlin, Germany from 1979 to 1984. She began trying to make ribosomes into crystals in 1970.  [1]
