She was born as Isabella Helen Lugoski in Detroit, Michigan, on December 2, 1921, the daughter of immigrants from Poland.[1] She attended the local public schools; while at school, a female chemistry teacher led her to her pursuit of the field as a career.[2] She attended the University of Michigan on full scholarship, where she majored in physical chemistry and received a Bachelor of Science at age 19, followed by Master of Science and Ph.D. degrees in the field. During her graduate work she met her future husband and scientific collaborator Jerome Karle; the two were both advised in their Ph.D. studies by Lawrence Brockway.[3][4]: 89
She joined the United States Naval Research Laboratory (NRL) after the end of the war. At the NRL, her husband Jerome developed "direct methods" for analyzing structure of crystals. However, for many years the crystallographic community remained skeptical about their utility.[1][6] Isabella Karle was the first person to apply the method. She developed the symbolic addition procedure that connects the theoretical "direct method" apparatus and actual X-ray diffraction data.[6] These contributions advanced the field of X-ray crystallography by enabling determination of the structure of crystals. This technique has played a major role in the development of new pharmaceutical products and other synthesized materials.[5]
In 1985, Jerome Karle was awarded the Nobel Prize in Chemistry, together with mathematician Herbert A. Hauptman, for developing direct methods for analyzing X-ray diffraction data. Jerome Karle and many other members of the crystallography community strongly believed that Isabella Karle should have shared the prize.[6][1]
On July 31, 2009, Karle and her husband retired from the Naval Research Laboratory, after a combined 127 years of service to the United States Government, with Karle joining the NRL in 1946, two years after her husband.[5] Retirement ceremonies for the Karles were attended by United States Secretary of the NavyRay Mabus, who presented the couple with the Department of the Navy Distinguished Civilian Service Award, the Navy's highest form of recognition to civilian employees.[5]
