Her theory that DNA consists of two helical structures was later confirmed by scientists James Watson and Francis Crick. Working with Maurice Wilkins and a doctorate student Raymond Gosling, she was able to correctly assess the structure of DNA. Next she embarked on her most important discovery, the structure of DNA molecule. She used x-ray imagery of coal to understand the changes occurring at molecular level in carbon when amorphous coal changes to solid graphite. During one such study she was introduced to the technique of x-ray crystallography and Rosalind was intrigued by its scope thus deciding on pursuing a career in this field. She did an extensive study on coals and classified them into different category on the basis of their efficiency as a fuel. It was when she enrolled at Cambridge that her scientific career truly began. Achieving stellar grades in the matriculation examination she received a scholarship but her father asked her to give the scholarship to deserving refugee student. Born to rich family, she pursued her education from premier institutions and was a bright student. Rosalind Franklin was a renowned chemist from England who did pioneering work in the field of X-ray crystallography.
