Isabella Helen Karle (née Lugoski; December 2, 1921 – October 3, 2017) was an American chemist who revolutionized crystallography laying the foundation for three-dimensional structures of molecules which facilitates the study of the biological, chemical, metallurgical, and physical characteristics of the molecules. This information provides the ability to synthesize those molecules. Her method improved the speed and accuracy of chemical and biomedical analysis and enabled the development of new pharmaceutical products and other synthesized materials.

For her scientific work, Karle received the National Medal of Science from President Clinton in 1995 "for the development and application of a method for determining essentially equal-atom crystal and molecular structures by x-ray analysis, thereby having a profound effect on the practice of organic and biological chemistry". She received several honorary doctorates and the Navy Distinguished Civilian Service Award (which is the Navy's highest form of recognition to civilian employees).
