Introduction Marie Curie who discovered two elements, was the first women to win a Nobel Prize in 1903, and was the first person to win a second Nobel, in 1911. But Curie was not the first female scientist. Many other brilliant, dedicated and determined women have pursued science over the years. Hypatia Hypatia was a Roman woman who, unlike most women during her time, received a good education. Hypatia studied mathematics, astronomy and natural science, and was appointed as the head of the University of Alexandria. She taught mathematics and philosophy. Hypatia wrote many books about math, and even invented several scientific instruments. Because of her teachings, a new ruler became angry with Hypatia and she was murdered. Her writings were destroyed, but she is one of the most well known women scientists in history. Hildegard of Bingen Hildegard wrote natural history books as well as medical books, and was the first person to write about the need to boil drinking water for sanitation. Hildegard also taught religion and medicine, and she emphasized the importance of exercise and diet. She is the first woman whose scientific writings still exist today. Florence Nightingale As a nurse she started the Nightingale School and Home for Nurses, and helped improve hospital conditions in India and England. Florence wrote books on nursing and hospital design, emphasizing the need for organization, cleanliness and compassion for the sick. Caroline Herschel She was a brilliant astronomer and discovered new nebulae and star clusters. She was the first woman to discover a comet (she discovered eight in total) and the first to have her work published by the Royal Society. She was also the first British woman to get paid for her scientific work. Mary Anning She had little formal education and taught herself anatomy, geology, paleontology and scientific illustration. Scientists of the time travelled far to consult and hunt for fossils with Anning. She was a fossil hunter. In addition to ichthyosaurs, she found long-necked plesiosaurs, a pterodactyl and thousands of other fossils that helped scientists to draw a picture of the marine world 200 million years ago during the Jurassic Age. Maria Mitchell Young Maria learned to observe the stars from her fathers. When she was 12, she helped her father record the time of an eclipse. At 17 she begun her own school for girls teaching them science and math. In 1847 she spotted a blurry streak – a comet – through her telescope. Mitchell was the first female astronomy professor in the United States. She observed mainly the sun and travelled up to 2,000 miles to witness an eclipse. Maria Telkes She was a physical chemist and biophysicist and was known for the invention of the solar distiller and the first solar-powered heating system designed for use in the home. Mathilde Krim She was a medical researcher and health educator and was known for her work in combating AIDS and HIV through research and education. Elizabeth Blackwell Elizabeth was the very first woman doctor in the United States. Elizabeth's sister Emily started a hospital staffed only by women doctors, and Elizabeth then opened a medical school for women. Gertrude Belle Elion Gertrude was inspired to study chemistry when her grandfather died of cancer and she wanted to help research this disease. Gertrude wrote more than 280 papers on her discoveries about drugs, and discovered or developed drugs that help fight leukemia, herpes, malaria, AIDS, and aid organ transplants. Gertrude and Dr. George Hitchings won the Nobel Prize in medicine for their work in developing drugs. When Gertrude was 73, she was invited into the National Inventors Hall of Fame, the first woman. There are more than 45 patents for drugs that Gertrude developed. Sally Ride Sally became the first woman astronaut to orbit Earth in space. She experienced weightlessness and even grew an inch because her spine was not compressed by gravity as it is on Earth. While in space, she performed many experiments, which help people to learn how to adapt to life in space.
