Ten Historic Female Scientists You Should Know
When it comes to the topic of women in science, Marie Curie usually
dominates the conversation. After all, she 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.
Emilie du Chatelet (1706 – 1749)
Gabrielle-Emilie Le Tonnelier de Breteuil, the daughter of the French
court’s chief of protocol, married the marquis du Chatelet in 1725. She lived
the life of a courtier and bore three children. But at age 27, she began
studying mathematics seriously and then branched into physics. This interest
intensified as she began an affair with the philosopher Voltaire, who also had
a love of science. Their scientific collaborations—they outfitted a laboratory
at du Chatelet’s home, Chateau de Cirey, and, in a bit of a competition, each
entered an essay into a contest on the nature of fire (neither won)—outlasted
their romance. Du Chatelet’s most lasting contribution to science was her
French translation of Isaac Newton’s Principia, which is still in use
today. At age 43, she fell in love with a young military officer and became
pregnant; she died following complications during the birth of their child.
Caroline Herschel (1750 – 1848)
Herschel was little more than the household drudge for her parents in
Hanover, Germany (she would later describe herself as the “Cinderella of the
family”), when her older brother, William, brought her to England in 1772 to
run his household in Bath. After she mastered the art of singing—to accompany
William, who was the organist for the Octagon Chapel—her brother switched
careers and went into astronomy. Caroline followed. In addition to assisting
her brother in his observations and in the building of telescopes, Caroline
became a brilliant astronomer in her own right, discovering 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, when
William, who had been named the king’s personal astronomer after his discovery
of Uranus in 1781, persuaded his patron to reward his assistant with an annual
salary. After William’s death in 1822, Caroline retired to Hanover. There she
continued her astronomical work, compiling a catalogue of nebulae—the
Herschels’ work had increased the number of known star clusters from 100 to
2,500. She died in 1848 at age 97 after receiving many honors in her field,
including a gold medal from the Royal Astronomical Society.
Mary Anning (1799 – 1847)
In 1811, Mary Anning’s brother spotted what he thought was a crocodile
skeleton in a seaside cliff near the family’s Lyme Regis, England, home. He
charged his 11-year-old sister with its recovery, and she eventually dug out a
skull and 60 vertebrae, selling them to a private collector for £23. This find
was no croc, though, and was eventually named Ichthyosaurus, the
“fish-lizard.” Thus began Anning’s long career as a fossil hunter. In addition
to ichthyosaurs, she found long-necked plesiosaurs, a pterodactyl and hundreds,
possibly thousands, of other fossils that helped scientists to draw a picture
of the marine world 200 million to 140 million years ago during the Jurassic.
She had little formal education and so taught herself anatomy, geology,
paleontology and scientific illustration. Scientists of the time traveled from
as far away as New York City to Lyme Regis to consult and hunt for fossils with
Anning.
Mary Somerville (1780 – 1872)
Intrigued by the x’s and y’s in the answer to a math question in a ladies’
fashion magazine, 14-year-old Mary Fairfax of Scotland delved into the study of
algebra and mathematics, defying her father’s injunction against such pursuits.
Her studies were sidetracked by a marriage, in 1804, to a Russian Navy captain,
but after his death she returned to Edinburgh and became involved in intellectual
circles, associating with people such as the writer Sir Walter Scott and the
scientist John Playfair, and resumed her studies in math and science. Her next
husband, William Somerville, whom she wed in 1812, supported these efforts, and
after they moved to London, Mary became host to her own intellectual circle,
which included the astronomer John Herschel and the inventor Charles Babbage.
She began experimenting on magnetism and produced a series of writings on
astronomy, chemistry, physics and mathematics. She translated astronomer
Pierre-Simon Laplace’s The Mechanism of the Heavens into English, and
although she was unsatisfied with the result, it was used as a textbook for
much of the next century. Somerville was one of the first two women, along with
Caroline Herschel, to be named honorary members of the Royal Astronomical
Society.
Maria Mitchell (1818 – 1889)
Young Maria Mitchell learned to observe the stars from her father, who used
stellar observations to check the accuracy of chronometers for Nantucket,
Massachusetts, whalers and taught his children to use a sextant and reflecting
telescope. When Mitchell was 12, she helped her father record the time of an
eclipse. And at 17, she had already begun her own school for girls, teaching
them science and math. But Mitchell rocketed to the forefront of American
astronomy in 1847 when she spotted a blurry streak—a comet—through her
telescope. She was honored around the world, earning a medal from the king of
Denmark, and became the first woman to be elected to the American Academy of
Arts and Sciences. In 1857 Mitchell traveled to Europe, where she visited
observatories and met with intellectuals, including Mary Somerville. Mitchell
would write: “I could not help but admire [her] as a woman. The ascent of the
steep and rugged path of science has not unfitted her for the drawing room
circle; the hours of devotion to close study have not been incompatible with
the duties of wife and mother.” Mitchell became the first female astronomy
professor in the United States, when she was hired by Vassar College in 1865.
There she continued her observations, particularly those of the Sun, traveling
up to 2,000 miles to witness an eclipse.
When
Lise Meitner finished school at age 14, she was barred from higher education,
as were all girls in Austria. But, inspired by the discoveries of William
Röntgen and Henri Becquerel, she was determined to study radioactivity. When
she turned 21, women were finally allowed into Austrian universities. Two years
of tutoring preceded her enrollment at the University of Vienna; there she
excelled in math and physics and earned her doctorate in 1906. She wrote to
Marie Curie, but there was no room for her in the Paris lab and so Meitner made
her way to Berlin. There she collaborated with Otto Hahn on the study of
radioactive elements, but as an Austrian Jewish woman (all three qualities were
strikes against her), she was excluded from the main labs and lectures and
allowed to work only in the basement. In 1912, the pair moved to a new university
and Meitner had better lab facilities. Though their partnership was split up
physically when she was forced to flee Nazi Germany in 1938, they continued to
collaborate. Meitner continued her work in Sweden and after Hahn discovered
that uranium atoms were split when bombarded with neutrons, she calculated the
energy released in the reaction and named the phenomenon “nuclear fission.” The
discovery—which eventually led to the atomic bomb (“You must not blame
scientists for the use to which war technicians have put our discoveries,”
Meitner would say in 1945)—won Hahn the Nobel Prize in 1944. Meitner,
overlooked by the Nobel committee, refused to return to Germany after the war
and continued her atomic research in Stockholm into her 80s.
Irène
Curie-Joliot (1897 – 1956)
The
elder daughter of Pierre and Marie Curie, Irène followed her parents’ footsteps
into the lab. The thesis for her 1925 doctor of science was on the alpha rays
of polonium, one of the two elements her mother discovered. The next year, she
married Frédéric Joliot, one of her mother’s assistants at the Radium Institute
in Paris. Irène and Frédéric continued their collaboration inside the
laboratory, pursuing research on the structure of the atom. In 1934, they
discovered artificial radioactivity by bombarding aluminum, boron and magnesium
with alpha particles to produce isotopes of nitrogen, phosphorus, silicon and
aluminum. They received the Nobel Prize in chemistry the next year, making
Marie and Irène the first parent-child couple to have independently won Nobels.
All those years working with radioactivity took a toll, however, and Irène died
of leukemia in 1956.
Barbara
McClintock (1902 – 1992)
While
studying botany at Cornell University in the 1920s, Barbara McClintock got her
first taste of genetics and was hooked. As she earned her undergraduate and
graduate degrees and moved into postdoctoral work, she pioneered the study of
genetics of maize (corn) cells. She pursued her research at universities in
California, Missouri and Germany before finding a permanent home at Cold Spring
Harbor in New York. It was there that, after observing the patterns of
coloration of maize kernels over generations of plants, she determined that
genes could move within and between chromosomes. The finding didn’t fit in with
conventional thinking on genetics, however, and was largely ignored; McClintock
began studying the origins of maize in South America. But after improved
molecular techniques that became available in the 1970s and early 1980s
confirmed her theory and these “jumping genes” were found in microorganisms,
insects and even humans, McClintock was awarded a Lasker Prize in 1981 and
Nobel Prize in 1983.
Dorothy
Hodgkin (1910 – 1994)
Dorothy
Crowfoot (Hodgkin, after her 1937 marriage) was born in Cairo, Egypt, to a pair
of British archaeologists. She was sent home to England for school, where she
was one of only two girls who were allowed to study chemistry with the boys. At
18, she enrolled in one of Oxford’s women’s colleges and studied chemistry and then
moved to Cambridge to study X-ray crystallography, a type of imaging that uses
X-rays to determine a molecule’s three-dimensional structure. She returned to
Oxford in 1934, where she would spend most of her working life, teaching
chemistry and using X-ray crystallography to study interesting biological
molecules. She spent years perfecting the technique, for which she was awarded
a Nobel Prize in 1964, and determined the structures of penicillin, vitamin B12
and insulin. In 2010, 16 years after her death, the British Royal Mail
celebrated the 350th anniversary of the Royal Society by issuing stamps with
the likenesses of 10 of the society’s most illustrious members, including Isaac
Newton and Benjamin Franklin; Hodgkin was the only woman in the group.
Rosalind
Franklin (1920 – 1958)
James
Watson and Francis Crick get credit for determining the structure of DNA, but
their discovery relied on the work of Rosalind Franklin. As a teenager in the
1930s, Franklin attended one of the few girls’ schools in London that taught
physics and chemistry, but when she told her father that she wanted to be a
scientist, he rejected the idea. He eventually relented and she enrolled at
Cambridge University, receiving a doctorate in physical chemistry. She learned
techniques for X-ray crystallography while in Paris, returning to England in
1951 to work in the laboratory of John Randall at King’s College, London. There
she made X-ray images of DNA. She had nearly figured out the molecule’s
structure when Maurice Wilkins, another researcher in Randall’s lab who was
also studying DNA, showed one of Franklin’s X-ray images to James Watson.
Watson quickly figured out the structure was a double helix and, with Francis
Crick, published the finding in the journal Nature. Watson, Crick and Wilkins
won a Nobel Prize in 1962 for their discovery. Franklin, however, had died of
ovarian cancer in 1958.
