Short Summary
Rosalind Franklin was a pioneering British scientist whose work significantly contributed to the understanding of DNA, RNA, viruses, coal, and graphite. She is most renowned for her X-ray diffraction images of DNA, which played a crucial role in the discovery of the DNA double helix structure. Despite facing discrimination in a male-dominated field, her meticulous research laid foundational insights into molecular biology. Her legacy continues to inspire and empower women in science.
Early Life & Education
Born in London on July 25, 1920, Rosalind Franklin was the second of five children in a well-to-do Jewish family. Her father, Ellis Franklin, was a banker, and her mother, Muriel, was active in community service. Franklin's inquisitive nature emerged early, and she excelled in academics, particularly in science and mathematics. She attended St. Paul's Girls' School, where she developed a passion for science. In 1938, she entered Newnham College, Cambridge, to study chemistry, later earning a Ph.D. for her work on the micro-structures of coal and carbon in 1945.
Career Highlights
Franklin's career began at the British Coal Utilisation Research Association, where her work on coal structure was highly regarded. In 1947, she moved to Paris to work at the Laboratoire Central des Services Chimiques de l'État, where she honed her expertise in X-ray crystallography. Returning to London in 1951, she joined King's College, where she conducted groundbreaking research on DNA. Her X-ray diffraction images, particularly Photo 51, provided critical insights into the structure of DNA. Later, at Birkbeck College, she shifted her focus to the study of viruses, making significant contributions to virology.
