Personal Biography

Rosalind Franklin was born in London, England on July 25, 1920. She died on the 16th of April, 1958 in London. Her father was against higher education for women. He wanted her to be a social worker. She attended one of the few girls' schools in London that taught chemistry and physics. Her father finally agreed to her going to school. She attended Newnham College, Cambridge. She graduated in 1941.


Franklin studied X-ray diffraction techniques in Paris. After she was finished there, she moved back to England. She became a research associate in John Randall's lab at King's College, London.

Franklin met Maurice Wilkins in that lab. They both worked on DNA, although Wilkins thought Franklin was just a technical assistant.

Franklin came close to solving DNA structure but was beaten to publication by Crick and Watson. The solution came to Watson after Wilkins had shown him one of her crystallographic photographs of DNA. The article was published in Nature. A supporting article about Franklin was also included.


Franklin is known for being responsible for much of the research and discovery work that led to the understanding of DNA.

Personal Biography

Francis Crick was born in Northampton, England, in June 8,1916. He attended University College College. He died July 28, 2004. Crick disapproved of royalty and disliked religion. He was also very private.

Scientific Biography

Crick developed radar and magnetic mines during World War 2. Crick also researched the structure of DNA with the University of Cambridge Medical Research Council with James D. Watson. Watson and Crick published the structure of DNA in 1953. He earned the Nobel Prize for Physiology or Medicine along with Watson and Maurice Wilkins.

BIology Legacy

Francis Crick is responsible for discovering the double-helix structure of the DNA strand along with James Watson and genetic code.

Personal Biography

Watson was born in Chicago on April 6, 1928. He studied at the University of Chicago. He also studied at Indiana University at Bloomington. He is unmarried, likes to birdwatch and walk.

Scientific Biography

Watson received a Ph.D. in Zoology. He got interested into learning genetics due to birdwatching. After Maurice Wilkins showed him the X-ray diffraction pattern of crystalline DNA he wanted to change the direction of his research to structural chemistry.

He met Crick later and worked together to solve DNA structure.

He is now part of the Harvard Biology Department.

Biology Legacy

Along with Crick he solved the structure of DNA.
