     Elizabeth Blackwell was bom in England in 1821, and moved

to New York City when she was ten years old. One day she decided

that she wanted to become a doctor. That was nearly impossible for

a woman in the middle of the nineteenth century. After writing

many letters asking for admission (录取) to medical schools, she

was finally accepted by a doctor in Philadelphia. She was so

determined that she taught school and gave music lessons to get

money for the cost of schooling.

     In 1849, after graduation from medical school, she decided

to further her education in Paris. She wanted to be a surgeon(外科

医师) , but a serious eye problem forced her to give up the idea.

start her own practice because she was a woman. By 1857

Elizabeth and her sister, also a doctor, along with another woman

doctor, managed to open a new hospital, the first for women and

children. Besides being the first woman physician and founding

her own hospital, she also set up the first medical school for women.
