• What life was like when Rosalind grew up

4
1920's

• Life was very exciting! WW1 had ended and
  everyone was very happy. Kids loved to play
  outside with all their friends. They liked to
  create friendship clubs and play imaginative
  games. They also liked to listen to their
  favorite radio shows since there were no TVs.

5
1930's

• The stock market crashed in 1929 and lots of
  things changed. People lost their jobs and their
  money.
• Kids had to quit school and help their families
  make money.
• People became very sad, which is why we call
  this time the Great Depression!

6
1940's

• The Great Depression was over and children went
  back to school and began playing again and having
  fun.
• Now children were
• playing war games because
• the whole world was at war,
• now known as WWII.

Rosalind Franklin(1920 1958)
Life as a scientist
8

• Rosalind Franklin always liked facts. She was
  logical and precise, and impatient with things
  that were otherwise. At 15 years old, she
  decided to become a scientist.

9
1938

• In 1938, Franklin passed the examination for
  admission to Cambridge University.
• This sparked a family crisis.
• Although her family was well-to-do and had a
  tradition of public service and philanthropy, her
  father disapproved of university education for
  women.
• He refused to pay.
• An aunt stepped in and said Franklin should go
  to school and she would pay for it.
• Franklins mother also took her side until her
  father finally gave in.

10
1941

• Franklin graduated from Cambridge University
  and began to work on her doctorate.
• Then she went to work with the British Coal
  Utilization Research Association where her work
  focused on a wartime problem the nature of coal
  and charcoal and how to use them most efficiently.

11
1945

• Franklin earned her PhD from Cambridge
  University.

12
1947 - 1950

• Franklin became proficient at applying x-ray
  diffraction techniques to imperfectly crystalline
  matter such as coal.
• Franklin published 5 landmark coal-related
  papers on graphitizing and nongraphitizing
  carbons.

13
1951 - 1953

• Rosalind Franklin went to Kings College where
  she first worked on living cells and DNA.
• In the spring of 1953, Franklin moved to
  Birkbeck College where she celebrated her work
  with J. Desmond Bernal on RNA viruses such as TMV
  (tobacco mosaic virus).

14

• Franklin made marked advances in x-ray
  diffraction techniques with DNA. She adjusted
  her equipment to produce and extremely fine beam
  of x-rays. She extracted finer DNA fibers than
  ever before and arranged them in parallel
  bundles. And she also studied the fibers
  reactions to humid conditions. All of these
  allowed her to discover crucial keys to DNAs
  structure.

15

• She began working with Maurice Wilkins. At this
  time women were not excepted in the field and she
  was not treated as an equal.
• Rosalind continued to work hard on her
  experiments. Her goal was to figure out what DNA
  looked like.

Maurice Wilkins
16
DNA is the code inside each person that makes us
all different. No one has the same DNA.
17

• Rosalind was taking pictures of DNA, and trying
  to put it all together when Maurice Wilkins took
  her pictures and showed them to Rosalinds
  competitors, Watson and Crick. When they saw
  these pictures they figured out what DNAs
  structure was.

Watson Crick
18

• Watson and Crick took all the credit for
  Rosalinds work.
• She worked so hard and Maurice Wilkins stole
  her work and showed it to other people.

1956 - 1958

• While on a professional visit to the United
  States, Franklin had episodes of the pain that
  she had soon learned were ovarian cancer. She
  continued working over the next two years,
  through 3 operations and experimental
  chemotherapy and a 10-month remission. She
  worked up until a few weeks before her death in
  1958 at age 37.
