Nettie Stevens
Nettie Maria Stevens was born in 1861 in Cavendish,Vermont. She was an American biologist and geneticist, whose research proved that chromosomes determine the sex of an organism. She completed in only two years the four-year course at Westfield Normal School in Massachusetts. Nettie graduated with the highest academic scores in her class. She recieved her B.A. in 1899 and her M.A. in 1900 at Stanford.
Nettie studied Tenebrio molitor beetles and found that unfertilized eggs in female beetles always contain an X chromosome. Sperm from male beetles contain either an X chromosome or a Y chromosome. She found that eggs fertilized by sperm carrying the X chromosome produce female beetles. The combination of egg and Y-chromosome sperm produce male beetles.
Edmund Beecher Wilson, a biologist from Columbia University in New York City, made this same discovery at about the same time as Nettie. Nettie also established that chromosomes exist as paired structures in body cells.
Nettie Stevens was not credited very well for her discovery. Instead, someone else was given the credit even though Nettie had done all of the work.
Nettie gained notoriety after her death in 1912, from Thomas Hunt Morgan. He stated:
Modern cytological work involves an intricacy of detail, the significance of which can be appreciated by the specialist alone; but Miss Stevens had a shre in a discovery of importance, and her name will be remembered for this, when the minutiae of detailed investigations that she carried out have become incorporated in the general body of the subject.
Rebecca Skloot has done a marvelous job telling the story of Henrietta Lacks; the woman who changed science!
Many women scientist upheld and defended their positions as learned, scientific individuals. Marie Meurdrac, a French scientist, in a foreword to a publication stated clearly that women’s and men’s minds, if thought in the same manner would hold no difference.(Doc 2) Similarly, Dorothea Erxleben understood and explained why men and women alike look down on her for studying science because they feel that it is an insult.(Doc 9) Her experiences as a female scientist led her to truly grasp why her persecutors acted as they did towards her although this document shows no signs that she thinks the same. Maria Sibylla Merian, a German entomologist, discussed some of her scientific practices that encompass her dedication and fascination with science.(Doc 5) Another example of this whole-hearted dedication comes from Marquis...
..., the name of Henrietta Lacks needs to be introduced to the world since she is the woman who generated HeLa cells, because the name of the person who generated HeLa cells is still unknown. By doing this, her family will be honored and respected by others.
Prior to the successful cultivation of HeLa cells, failure was met with every attempt to grow cells in culture. This roadblock became the focused work of Dr. George Gey of Johns Hopkins University. Johns Hopkins served most of the impoverished black community seeking care in the immediate Maryland area. This provided a goldmine for medical research that was justified by its “generosity” and Samaritan charter. Henrietta Lacks decision to seek care for her cervical cancer unknowingly designated her as arguably the single greatest contribution to science and medicine. After the realization that human cells had finally been successfully harvested and reproduced, Dr. Gey immediately distributed the cells and his methodology to anyone who asked. As the explosion of research on HeLa cells swept across the scientific community many of Dr. Gey's colleagues urged him to publish or patent cells to take credit for his for work but his dedication to the work rather than the credit prevented him from doing much publishing if any at all. The implica...

He entitled his findings English Men of Science: Their Nature and Nurture (Galton, 1874). He also pioneered the use of twin studies. He would survey sets of twins, which resulted in findings that supported his theory of heredity. Galton found that the twins he surveyed showed many similarities, even if their environments had been very different for a long period of time. Twin studies are still used today to study the effects of nature versus nurture (Goodwin, 2012, p. 153-154).
Price Waterhouse should educate its partners and employees about accepted work practices and should institute diversity training in order to educate members that stereotyping is unacceptable. Ann Hopkins should be admitted as partner to the firm and welcomed as a valuable addition to senior management.
Female scientists such as Maria Merian and Marquise Emilie du Chatelet had an impact on western science, demonstrating how women were capable of contributing to the sciences despite society’s opinions. Merian published her book Wonderful Metamorphoses and Special Nourishment of Caterpillars during a time when women were criticized for publishing books and demonstrates how society was not able to completely repress women in science (Doc 5). Marquise Emmilie du Chatelet’s letter to the Marquis Jean Francois de Saint-Lambert also demonstrates how women refused to be repressed by society. She refuted his reproach of her translating Newton’s Principia, a translation so thorough it is still used today (Doc 11). Some men in the sciences also gained a respect for women and their contributions. Not all men at the time believed women were incapable of learning at a university level like Junker did. Gottfried Leibniz, a German mathematician, even went as far as to state “women of elevated mind advanced knowledge more properly than do men.” As a philosopher Leibniz likely thought beyond society’s opinions, which is why he did not conform (Doc 7). Johannes Hevelius and Gottfried Krich disregarded the notion that collaborating with women was seen as embarrassing, and both collaborated with their wives (Doc 4 and Doc
Susan Smith could have been a normal woman. If you passed her on the streets you wouldn’t know that she would turn out to be a killer. Susan had a secret though, a deadly secret. Susan Smith was a cold, calculating killer, capable of murder in cold blood. I believe Susan had many factors contributing to the state of mind she had before the murder of her two sons, like her traumatizing childhood and the many dysfunctional relationships she had.
Rosalind Franklin: Seeing a woman as a scientist during this time is somewhat rare, so the fact that she has taken up this profession show that she is persistent, dedicated, and smart. The only problem is that she is undervalued because of her gender. She is also very quiet and reserved because she’s in a different country.

When most people think of the Scientific Revolution, they think of scientists such as Galileo, Newton, Brahe, and Boyle. However, many people do not even know about the many women who played a vital role in the scientific advancements of this period. Even when these women were alive, most of society either ignored them or publicly disapproved their unladylike behavior. Because of this, these women were often forgotten from history, and very little is known about the majority of them. Although their names rarely appear in history books, the female scientists of the Scientific Revolution still impacted the world of science in several ways. In fact, all of the scientists listed above had a woman playing an influential role assisting them in their research. However, assisting men in their studies was not the only role open to women; several women performed experimentation and research on their own, or advancing science in some other way, even though the society of the time looked down upon and even resisted their studies.
