Why have the discoveries of women scientists been attributed to men throughout history?


Women scientists lead revolutionary scientific research, however, despite their extraordinary discoveries, women worldwide represent only 30 percent in science, according to data from the United Nations (UN). Female scientists are rarely recognized for their achievements – only three percent of Nobel Prizes in science have ever been awarded to women, and only 11 percent of women are in senior research positions leading projects in Europe.

Globally, the enrollment of female students is particularly low in information and communication technologies – three percent, in natural sciences, mathematics and statistics – five percent and in engineering, manufacturing and construction – eight percent.

Today, women make up half of the workforce, earn more university degrees than men and, according to some estimates, represent the single largest economic force in the world. Still, gender gaps in science persist more than in other professions, especially in cutting-edge, math-intensive fields like computer science and engineering.

Many cultural barriers to women continue to stand in the way of science, from directing girls to other occupations, gender bias, stereotypes and sexual harassment in a male-dominated workplace to possible career restrictions for women due to childbearing. The contribution of women to science that remained unrecorded is not surprising because since the emergence of professional science in the 19th century, women scientists, with notable exceptions, often did not receive credit for their work. Also, the work of those who collaborated with men, most often relatives, was often attributed to the work of their brothers, fathers or husbands.

Science and gender equality are vital to achieving internationally agreed development goals, including the 2030 Agenda for Sustainable Development, according to the UN. Over the past 15 years, the global community has invested a lot of effort in inspiring and involving women and girls in science. However, women and girls are still excluded from full participation in science.

Ever since the UN General Assembly declared February 11 as the International Day of Women and Girls Scientists in 2015, the goal has been to raise awareness of the issue that celebrates female excellence in science. Throughout history, although famous scientists like Marie Curie and Jane Goodall were eventually recognized for their contributions to science, a significant number of female scientists were overlooked and marginalized simply because of their gender. However, despite the challenges of gender discrimination and lack of recognition in the scientific community, countless inspiring women in these fields have made historic contributions to science and helped advance our understanding of the world around us. Many were not recognized during their lifetime, but their achievements helped new generations of female scientists.

Women in science, neglected in history

One of the closest examples of the omission of women from the history of science in the Balkans is the story of Mileva Marić, a Serbian physicist and mathematician, Albert Einstein’s first wife. The marriage of Albert Einstein and Mileva Marić was the relationship of two brilliant minds, one of which characterized the 20th century, and the other became an example of a stumbling block encountered by female scientists.

Mileva Marić (1875-1948) was a physics student in Switzerland when she met Albert Einstein, who was 17 years older.

Mileva Marić did not publish any research or claim credit for any of Einstein’s discoveries; any work they did together was done in privacy. All arguments for and against her participation in Einstein’s discoveries are circumstantial. But the lack of direct evidence has never stopped debates about her contribution. The letters Milevi wrote to Einstein in which he talks about the ideas of relative motion and molecular forces – for which he later became famous – contain the words “we” and “our” referring to research.

As Nature magazine writes, the controversy about Mileva’s contribution to science and Einstein’s research was stirred up by the biography of Mileva Marić from 1969, prepared by high school teacher Desanka Trbuhović-Gjurić. The book claimed that Mileva’s contribution to Einstein’s success was “large and significant”. That assessment was based on the testimony of contemporaries, Mileva’s early academic success, and Einstein’s 1921 Nobel Prize legacy as part of the divorce settlement. Later, the linguist Senta Troemel-Ploetz and the physicist and parapsychologist, Evan Harris Walker, interpreted the letters the pair wrote to each other as evidence that Mileva’s ideas were central to Einstein’s pursuit of science.

Lise Meitner (1878-1968) was a nuclear physicist born in Vienna who was the first woman with the title of professor of physics in Germany.

She worked with fellow scientists Otto Hahn and Otto Robert Frisch and was part of a small team that discovered nuclear fission, a process that would later help develop nuclear weapons and generate electricity.

Meitner not only suffered gender discrimination in the workplace during the 1930s, but also the greater threat of ethnic cleansing. She lost many prestigious academic positions because of the anti-Jewish laws enforced by the Nazis. She eventually fled to Sweden and acquired dual citizenship there.

Although she received numerous prestigious awards later in life, Lise Meitner was not the winner of the 1944 Nobel Prize in Chemistry, which was awarded solely to her fellow scientist Otto Hahn for the discovery of nuclear fission. Many scientists later said that the exclusion of Lisa Meitner by the Nobel committee was “unfair”.

Rosalind Franklin (1920-1958) was a British chemist who researched DNA.

The data from her research was the first to show the basic dimensions of DNA chains and revealed that the molecule is in two matching parts, which go in opposite directions. Her discoveries were used by James Watson and Francis Crick to supplement their research on the DNA model. These studies were published as supplementary data along with research articles by Watson, Crick and Maurice Wilkins in the journal Nature.

Many in the scientific community argue that Rosalind Franklin should have received the Nobel Prize together with Watson, Crick and Maurice Wilkins in 1962 “for their discoveries concerning the molecular structure of nucleic acids and its importance for the transmission of information in the living organism”. Sadly, Rosalind died of ovarian cancer in 1958, just four years before the prize was awarded. At that time, the Nobel Committee could also award the prize posthumously.

Nobel Prize in Chemistry 2022: Honors for three scientists developing click chemistry

The Americans Carolyn Bertozzi and Barry Sharpless, as well as the Dane Morton Meldal, are the winners of this year’s Nobel Prize in Chemistry for their work on joining molecules – in the field known as click chemistry.

Click chemistry is a branch of science that deals with the study of how to connect different molecules into a single whole. Their work is used in cell research and the monitoring of biological processes, and it can also be applied to drugs for the treatment of cancer. The Nobel committee praised their work, which they say will make chemistry more efficient, adding that the impact of their research can be seen in science.

“With this year’s prize, we want to show that not everything has to be complicated, but that things can be made easy and simple,” says Johan Acquist, chairman of the Nobel Committee for Chemistry.

The winners will share a prize of ten million Swedish kronor (about 912,000 euros). Bertocci, a pioneer in bioorthogonal chemistry, is the eighth woman to win the Nobel Prize in Chemistry.

“I am delighted, I can hardly breathe,” said Bertossi after being informed of the prize by the Nobel committee.

Her discoveries can be applied in medicine and pharmacology, she explained. This means that scientists can “apply chemical research to the human body by monitoring whether the drug ends up in the right place and keeps it away from where it shouldn’t.” It’s also a “biological tool” that will help scientists spot molecules they didn’t know existed, she added. Barry Sharpless won the Nobel Prize for the second time. 21 years ago, he became a Nobel laureate thanks to his work on chiral catalysts.

Sharpless and Medal worked separately, but they
The Nobel Committee last year awarded the prize to scientists for developing ways to construct molecules. Swedish physicist Svante Pabo received the Nobel Prize in Physiology and Medicine for Neanderthal DNA research.

Three scientists, French Alain Aspe, American John Clausur and Austrian Anton Zeilinger, received the Nobel Prize in Physics on October 4, for research in the field of quantum mechanics – the science that describes nature using particles smaller than atoms.

Previous winners of the Nobel Prize in Chemistry

2021 – Benjamin List and David McMillen, awarded the Chemistry Prize for developing a new way to construct molecules.

2020 – Emmanuelle Charpentier and Jennifer Doudna won the prize for inventing tools to modify DNA.

2019 – John B. Goodenough, M. Stanley Whittingham and Akira Yoshino shared the prize for their work on lithium-ion batteries.

2018 – Francis Arnold, George P. Smith and Gregory Winter were awarded for the discovery of enzymes.

2017 – Jacques Dubochet, Joachim Frank and Richard Henderson were awarded for advancing the picture of biological molecules.

2016 – Jean-Pierre Sauvage, Fraser Stoddart and Bernard Feringa won the prize for a machine made of molecules.

2015 – Tomas Lindahl, Paul Modric and Aziz Sankar were awarded for their work on DNA repair.

Marie Curie – the first world-famous and recognized scientist

“There is nothing to be afraid of in life. Life just needs to be understood.”

“Life is not simple for any of us. How to deal with it? We must persevere and above all believe in ourselves. We must believe that we are gifted for something and that it must certainly be achieved.”

Marie Curie is not only the first woman to receive the Nobel Prize, but also the first person to receive the award twice, and the only woman to receive it in two different categories. Secluded, dignified and modest, she gained the admiration of scientists all over the world.

Marie Curie valued education from an early age and as a child stood out above other children. At the age of 5, Maria learned to read and write, listening to her sister learn the alphabet. From the beginning of her schooling, she was a brilliant student, and at the end of high school she was awarded a gold medal for her success. However, her homeland, Poland, was then under Russian domination, and women could not attend university. As her desire for education was strong, Marie Curie (then Sklodowska) found a solution and soon connected with a group of young people who organized their studies in a non-compulsory organization called the Mobile University.
In 1891, she went to Paris to live with her sister and studied mathematics, physics and chemistry at the Sorbonne. She finished her studies at the Sorbonne as the best student, first in the physics and chemistry class, and second in the mathematics class.

She met her future husband, Pierre Curie, who was then a doctoral student in Becquerel’s laboratory, in 1894 and married him the very next year, after Pierre defended his doctorate.

She began her first research under the influence of Becquerel, who discovered in 1896 that uranium salts emit rays that are as penetrating as x-rays. Encouraged by this discovery, Marie Curie decided to study uranium rays as part of her doctoral dissertation. She showed that this radiation originates from the atom itself. She then continued her systematic studies of radioactive substances, especially uranium, and came to the discovery that uranium pitch has four times stronger radiation than elemental uranium, which led to the conclusion that some other elements are also present. Through various researches, she came to the discovery that this activity of uranium particles is also characteristic of some other substances (thorium) and decided to call this phenomenon radioactivity. Her husband, Pierre Curie was intrigued by her discoveries and decided to join her.
In 1898, the Kiri couple discovered the existence of a new element. The newly discovered element was called “polonium”, in honor of Mary, the homeland of Poland. A few months later, they announced other results of their research and the existence of another element. Because of its high radioactivity, it was called “radium”. They came to this discovery after painstaking work in a laboratory located in a shed and extensive research in which they processed 8 tons of uranium ore, and only in 1902 did they isolate one tenth of a gram of radium.

The crown of all research came in 1903. years. Pierre Curie, Marie Curie and Henri Becquerel received the Nobel Prize in Physics, in recognition of their outstanding achievements in the field of radioactivity. Thus, Mrs. Curie became the first woman to be awarded by the Swedish Royal Academy of Sciences.

In the same year, Maria received her doctorate from the University of Paris and became the first woman in France to achieve that academic degree. After these successes, recognitions from other European countries followed.

The Kiri couple not only discovered new elements, but also the effects of radioactivity on cells. They made an important discovery – that sick, cancerous cells exposed to radiation are destroyed much faster than healthy ones. In order to enable the operation of this, the first laboratory in the world, which carried out experiments by treating cancer cells with radioactive substances, it sought the help of other countries, and the USA was one of the countries from which it received valuable help. President Harding, on behalf of the women of America, gave her 1 gram of radium for her institute, which for her was “countless times more precious than gold”.

This discovery played a huge role in the subsequent research and development of therapy for the treatment of many forms of cancer. Radiological therapy is still the main therapeutic method in the treatment of cancerous diseases.

After becoming an unfortunate widow in 1906, Marie Curie was asked to take over her late husband’s university professorship. That’s how she became the first woman professor at the Sorbonne.

She continued to work hard and dedicatedly, and in 1910, with the help of her colleague, she isolated pure metallic radium. The award for all the research and discovery of the chemical elements radium and polonium, for the isolation of radium and the study of the nature of that element and its compounds, arrived the following year in the form of another Nobel Prize. This time it was the Nobel Prize for Chemistry. Thus, Marie Curie became the first scientist with two Nobel Prizes.

Through further research, she realized that X-rays can help locate foreign objects in the body and thus facilitate the surgeon’s work. During the First World War, Marie Curie, with the help of her daughter Irene, who she also included in her scientific activities, devoted herself to developing the medical application of radiography. She designed a vehicle that was used for radiography, and which was sent to the front to help wounded soldiers. The vehicle became known as the “little kiri”, as it was fondly called. Marie Curie personally brought him to the front line. The vehicles were equipped with radon, a radioactive gas derived from radium, which Maria personally collected and placed in gas pipes.

At the time when Marie Curie was researching the harmful effects of radiation, they were still unknown, so the Curie couple conducted research without any protection from radioactive substances. It was even said that Marie Curie loved the beautiful blue-green light with which substances glowed in the dark, and that she even carried test tubes with radioactive isotopes in her pocket and kept them in her desk drawer. The intensity of radioactivity to which the Curies were exposed was so high that their laboratory equipment, books and notes are still considered too dangerous to handle.

Marie Curie died of leukemia on July 4, 1934. She was buried in the cemetery in Scow next to her husband Pierre. In honor of their achievements, in 1995 the French moved their remains to the Panthéon in Paris.
