Some Asian Women Pioneers of Chemistry and Pharmacy

At present, several countries on the Asian continent are still very closed off to the idea of allowing not only the work of women, but also even the fact that they can study university degrees and, after finishing them, go on to practice their professions. In addition, if we go back to the beginning of the 20th century, this situation was even more serious. However, this was not an impediment for some women from these countries to achieve their goals of pursuing higher education and then serving society with their work. This article is dedicated to showing the biographies of three of them, the Indian chemist Asima Chatterjee and Philippine pharmacists Matilde S. Arquiza and Filomena Francisco. The most relevant features of their personal and professional lives are presented and previous biographies about them are completed. The main objective of this work is to show these figures to society and hold them up as references to other people, and the methodology followed has been the search for data about their lives and work that would allow us to complete the previous existing biographies about them. A brief biography on Janaki Ammal, the first Indian woman to obtain a doctorate, is also included.


Introduction
There is not much information in the literature about Asian scientist women who have stood out in their fields of research in the first decades of the 20th century; however, there have been some among them, very unknown in wider society, who undoubtedly deserve to have that recognition by virtue of the achievements they made or because of the work they carried out in their professions.
This article is dedicated to showing the biographies of three of these women, one of them born in India, Asima Chatterjee, graduate in chemistry, who has the honor of being the first woman doctor in sciences in that country. The other two women are the Philippine pharmacists Matilde S. Arquiza and Filomena Francisco, of whom very little is known regarding their lives and works, yet who, however, are clearly pioneers of the profession in their countries and contributed to opening the door for the that the rest of the women who graduated in that discipline.
The main objective of the article is to complete the literature with novel data from the authors' own research the biographies already existing in the literature, in order to hold them up as references to society and as an example of women who had to overcome numerous difficulties throughout their lives, mainly barriers related to gender, to be able to achieve what they wanted: to study a university career, scientific in the case of the three, and be able to pursue a career in their studied areas upon completion. In 1945, she married Dr. Baradananda Chatterjee, an eminent physical chemist wh became Professor and Head of the Department of Chemistry, Geology and Metallurg and Deputy Director of the Bengal College of Engineering. Figure 2 shows Asima Chat terjee with her daughter, Julia and her husband. Her husband always exerted a great influence on her, inspiring and stimulating he on the one hand and helping her with some of her domestic tasks on the other, which allowed her to also dedicate herself to science and carry out her work. Thanks to the good work of her husband, the members of the laboratory that he directed considered them selves as a family. He also used to meet with them on Saturday nights and holidays, ad vising them even on personal problems that they mentioned to him [1]. For her part, sh always tried to instill in her only daughter, Julia, who had come very soon to the marriage the same taste and enthusiasm that she had for organic chemistry. Thanks to those effort of her mother, Julia, who married Professor Avijit Banerji, also from the Department o Chemistry at the same university-and had a son, Aniruddha Banerji-became Head o the Department of Chemistry at the University of Calcutta. In 1945, she married Dr. Baradananda Chatterjee, an eminent physical chemist who became Professor and Head of the Department of Chemistry, Geology and Metallurgy and Deputy Director of the Bengal College of Engineering.

With large quantities of these com pounds, she was able to study their mechanisms of action against diseases such as cancer epilepsy and malaria. As a result of her work and research, she received several award and distinctions: the Calcutta University Silver Medal and Prize and the Jogmaya Dev Gold Medal.

In the 1947-1948 academic year, Asima Chatterjee began a stay of several years in the United States, where she first worked with Professor Parks, from the University of Wisconsin, on natural glycosides. In 1948-1949, she worked with with Professor Zechmeister, of the California Institute of Technology (Caltech) of Pasadena, in carotenoids and provitamin A (in recognition of that work, she was awarded the Watumull Scholarship). In the 1949-1950 academic year, she worked with Professor P. Karrer of the University of Zürich on biologically active alkaloids. All these studies focused on the chemistry of natural products, allowing her to obtain anticonvulsant drugs, malaria drugs and chemotherapy drugs [1,4].
Returning to India in 1954, Asima Chatterjee ( Figure 3) worked at the College of Science, University of Calcutta, as a lecturer in Pure Chemistry. and in 1962 joined the prestigious Khaira Professorship of Chemistry at the University of Calcutta, a position she maintained until 1982 [1].

Unfortunately, the year 1967 was very sad for Asima. Firstly, she lost her father, and then her husband four months later. These two tragedies caused her to suffer a severe heart attack in the same Faculty of Sciences of the University of Calcutta, which caused her to be hospitalized in a critical condition, in which she remained for several days. It took her almost three months to recover, although eventually the support and affection of her students, colleagues and staff members in the Department of Chemistry helped her return to normal activities [1].

Figure 4 shows Asima Chatterjee with her students in 1997.  One of Asima Chatterjee's passions was learning about the medicinal properties of native Indian plants. She was a very prolific writer, who published around 400 articles in impact national and international journals [7], and all this despite the great economic difficulties she encountered. One of her doctoral students, S.C. Prakashi, remembered that [1]: One of Asima Chatterjee's passions was learning about the medicinal properties of native Indian plants.

One of her doctoral students, S.C. Prakashi, remembered that [1]: "Being one of her first doctoral students, I have witnessed her initial difficulties in establishing himself. Those were tough days for research, particularly in a poorly equipped university, laboratories with inadequate chemicals, and little financial assistance. Institutions like the Department of Science and Technology or the Department of Biotechnology under the government were yet to come and the Council for Scientific and Industrial Research (CSIR) was in the formative stage." Throughout her academic life and as a result of her work, Asima Chatterjee obtained many awards and distinctions in recognition of her scientific contributions. Among them, she became a Premchand Roychand Scholar at the University of Calcutta and was the second woman to obtain a doctorate from an Indian University, the University of Calcutta, in 1944 (she was the first woman to obtain a Ph.D. in science in India, but the first woman to obtain a doctorate in any discipline from an Indian university was Edavaleth Kakkath Janaki Ammal (1897-1984), an Indian botanist and cytologist who made important contributions to genetics, evolution, phytogeography and ethnobotany [8]). Further information on her can be checked in Appendix A and also on other Asian pioneer scientific women in Appendix B.
Asima Chatterjee ( Figure 5) was also made Khaira Professor of Chemistry, one of the most prestigious chairs at the University of Calcutta, from 1962 to 1982. In 1972, she was appointed Honorary Coordinator of the Special Assistance Program to intensify teaching and studies in natural chemistry, sanctioned by the Commission of Indian University Grants. In 1960, she was elected to the Indian National Science Academy, New Delhi. In 1961, received the Shanti Swarup Bhatnagar in Chemical Science, India's most prestigious science award [6], the first woman to do so (even though the award was first introduced in 1958, but it 'was not until 1960, that the "chemical sciences" category was introduced; Asima Chatterjee won the award for her contribution and achievements in phytomedicine: the study of plant extracts for therapy). It took over 14 years for another woman to win the same prize, and over 48 years for a woman to win it in the "chemical sciences" category [9].
In 1975, she was conferred with the prestigious Padma Bhushan, the third highest civilian award from the Government of India. That same year, precisely recognized as International Women's Year, she was honored by the Bengal Chamber of Commerce as Woman of the Year for her scientific contributions. She also won the S. S. Bhatnagar Award, the C. V. Raman Award and the P. C. Ray Award, all considered highly prestigious. She was also the first woman to be elected General President of the Indian Science Congress Association, a premier institution that oversees scientific research in the country, and was appointed Doctor Honoris Causa by several Universities and nominated by the Presidency of India as a Member of the Rajya Sabha from 1982 to 1990 [1]. phytomedicine: the study of plant extracts for therapy).

Her research, framed in the fields of organic chemistry and phytomedicine, focused on studies on vinca alkaloids and the development of drugs obtained from plant extracts for the treatment of epilepsy and malaria (vinca alkaloids, originally derived from" Catharanthus roseus", are antimicrotubule and mitotic inhibitor drugs that block cell growth by preventing mitosis; therefore, they are used in cancer treatment [1].

Some of these alkaloids are efficiently used during chemotherapy to prevent the multiplication of cells in cancer patients. These patented drugs have been widely marketed by several companies. Asima Chatterjee (Figure 6) also chemically analyzed coumarins, which came from the bael tree, a native species in India. It was she who brought to light that the fruits and bark of this tree could treat a variety of gastrointestinal disorders.
She was also the author of a considerable volume of texts, around 400 articles and books, on medicinal plants of the Indian subcontinent. At the request of Professor Satyendra Nath Bose, FRS, she wrote "Sarai Madhyamic Rasayan", a book in Bengali on Chemistry for high school students, which was published by Bangiya Bijnan Parishad, an Institute for the Popularization of Science founded by Professor Satyendra Nath Bose. According to the Indian Academy of Sciences, Asima Chatterjee [2]: "( . . . ) successfully developed the antiepileptic drug, Ayush-56 from Marsilia minuta and the antimalarial drug from Alstonia scholaris, Swrrtia chirata, Picrorphiza kurroa and Ceasalpinna crista".

Pioneering Filipino Women in Pharmacy
A year after being founded in 1904, the Pharmacy School of the Liceo de Manila, currently the Manila Central University (Figure 7), The Philippines, already more than five years independent from Spanish domination, offered women the opportunity to join the study of pharmacy, a field that until then was forbidden to women, which at that time was a profession with the same prestige as medicine (which was also closed to them). The first women to obtain their degrees, and later their licenses, were Filomena Francisco and Matilde S. Arquiza Arroyo, the only women who took the Pharmacy exams between July 1 and 3, 1908, obtaining two of the first three places, according to the results indicated by the examiners. Only 25 of the 39 presented future pharmacists-to-be passed the exams:Filomena Francisco occupied the first place and Matilde S. Arquiza the third, while a man, Nemesio Dimanlig, occupied the second place [11].

This subsection presents the biographies of those first two Filipino women to graduate in Pharmacy. As indicated above, Filomena Francisco was the Filipino woman who ranked first in the examinations held in the islands in 1908 for applicants aiming to become future pharmacists.
Filomena Francisco Guerrero (née Filomena Francisco) was born in 1886, somewhere As indicated above, Filomena Francisco was the Filipino woman who ranked first in the examinations held in the islands in 1908 for applicants aiming to become future pharmacists.
Filomena Francisco Guerrero (née Filomena Francisco) was born in 1886, somewhere in the Philippines, on day and month still unknown, in the bosom of a large family with limited economic resources, in which the idea that the children would be able to study was considered an unthinkable luxury. Her father was Gabriel Beato Francisco, a downtrodden journalist who had been the manager of "El Comercio", the main business newspaper during the Spanish regime.
At the age of 15, Filomena Francisco ( Figure 9) entered domestic service in the house of a family with a very good economic position and managed to convince the owners of the house to allow her to study at night, to which they agreed, as that way, she was able to get to university. However, at one point, the owners thought that the school of pharmacy was not for girls, so they forced her to choose between continuing her work at home or pursuing her career. She chose the latter and continued studying pharmacy at the university, also obtaining the best qualifications in her class. To pay for her studies, she began teaching at the Centro Escolar de Señoritas (currently Centro Escolar University) in 1907, graduating in 1908, after which she established her pharmacy in Manila, the "El Carmen Pharmacy", in 1910 [13].
It is important to note that Filomena Francisco finished her Pharmacy degree after marrying Dr. Alfredo León Guerrero and assuming the role of "submissive and obedient wife and mother", since her in-laws considered that it is "unethical for a doctor's wife to have a pharmacy" [15].
The couple had three children, León, Mario X. and Carmen, two of whom, León and Carmen, would later become very important figures in the Philippines, as would their granddaughter, Gemma Cruz-Araneta Guerrero, daughter of Carmen.
Not much information is known about Filomena Francisco related to her person or her profession as a pharmacist. Regarding her personal characteristics, it is known that in December 1907, the Filipino, American and Spanish communities began to nominate candidates for the queens of the first Manila Carnival. The official list included Josefina Ocampo, Purita Villanueva, Leonarda Limjap and Pilar Reyes Cobarrubias, all of them beautiful and above all wealthy women, but the opinion of the inhabitants of Manila meant that Filomena Francisco ought to be also included, because she was a "student at the Liceo de Manila, known for its intellect and moral values".
Regarding the exercise of her profession, it is known that she researched in chemistry and biology, studying the relationship between pharmacopoeia and bacteria. Together with Ramón Diokno, she was the founder of the "School Association of the Philippines" and also participated in 1905 in the founding of the "Female League for Peace" along with To pay for her studies, she began teaching at the Centro Escolar de Señoritas (currently Centro Escolar University) in 1907, graduating in 1908, after which she established her pharmacy in Manila, the "El Carmen Pharmacy", in 1910 [13].

In addition, Filomena Francisco wrote some successful novels at the time, although no references to the details of these were found. Pedro V. Paterno, from Nacional High School, dedicated to her, among other women, his collection of short novels entitled "Aurora social" [16].
Filomena Francisco died in 1949, presumably in Manila, although no source reports her death.

Discussion
This article is dedicated to recalling the figures of some Asian women, specifically from India and the Philippines, who were pioneers of science, specifically of pharmacy and chemistry, with the aim of making them known and holding them up as references to the society, having been able to first face and then overcome all the barriers related to their gender imposed on them to study and practice their professions in countries in which at that time the role of women was not valued. Note that the fact that these women in Asia chose the path of academic learning and that, above all, they did so apart from the maternal discipline expected of them. Higher education simply did not include women, neither in those countries nor in many other countries throughout the world. As an example, in 1913, literacy among women in India was less than 1%, meaning fewer than 1000 women in total across the country were enrolled in school.
The women discussed in this article are the Indian Asima Chatterjee and the Filipinos Matilde S. Arquiza and Filomena Francisco.
As well as being a leader in Phytomedicine, Asima Chatterjee was a pioneer in science for women. As already noted, she founded the department of chemistry at Lady Bradbourne College, University of Calcutta, and her Ph.D. was the first Ph.D. in science awarded to a woman by an Indian university. She was the recipient of the Shanti Swarup Bhatnagar Prize in Chemical Sciences (the first woman to receive the prize), a fellow of the Indian National Academy of Sciences, and the first female General President of the Indian Science Congress Association. She passed on her passion for science, and in particular, for chemistry, to her daughter, Julie, thanks to which she became a successful organic chemist. She also served as an inspiration and mentor to numerous students and colleagues [1].
In her 40-year career, she developed several drugs that were used to treat epilepsy and malaria, among others that were used in chemotherapy. The anti-epilepsy drug Ayush-56, discovered by Asima Chatterjee, is still used. She also wrote many books in English and Bengali.
Asima Chatterjee further presented a great example of the much-desired work-life balance: she enjoyed cooking, spending time with her family and the simple joys of family life. She worked until the end of her life, passing away peacefully at the age of 90. Her daughter followed in her footsteps and also became a chemist [17].
For their part, the first two Filipino women pharmacists, Matilde S. Arquiza and Filomena Francisca, were the ones who first opened the door: after them came many other Filipino women, who also contributed to the development of science in their country.
Although not much information is available about all of them in the literature, overall, in the case of the Filipino women, for the reasons mentioned above alone, they deserve to be remembered and recognized.
Allow us, therefore, to finish the biographies of these exceptional women by showing our admiration and respect towards them.

Appendix A
Although she has not been dealt with in this article, because she was not a woman who dedicated herself to chemistry or pharmacy, but to botany, the authors believe it is fair to dedicate a few lines of this article to also remember the figure of Edavaleth Kakkath Janaki Ammal (Figure A1), the first Indian woman to obtain a doctor's degree, although she did not obtain it at a university in her country, but at Queen Mary's College of the University of Michigan. Edavaleth Kakkath Janaki Ammal (4 November 1897-15 February 1984) was the first Indian woman to earn a Ph.D., and in 1931, the first female scientist to become a member of the Indian Academy of Sciences, and probably the first female salary earner at the John Innes Institute and the first to be awarded a Padma Shri in 1977. She was botanist and cytologist and made important contributions to genetics, evolution, phytogeography and ethnobotany.
She was the tenth child in a family of 19 brothers and sisters. Her father was Dewan Bahadur Edavalatt Kakkak, a sub-judge of the Madras Presidency and her mother was Devi. She grew up in Tellicherry (now Thalassery), in the Indian state of Kerala. In the family, girls were encouraged to engage in intellectual pursuits and fine arts, and she chose to study botany. Indeed, her family home had a garden that they cared for and shared, and especially involved was her father, a nature lover who came to write two books about the native birds of the North Malabar region. It was in this environment that Janaki Ammal found her affinity for the natural sciences [18].
As she grew older, Janaki Ammal saw how many of her sisters were destined for arranged marriages. Unprecedented, when the time came, he made three very important decisions that marked her life: the first, to remain single all her life, so as not to be subordinated to those family burdens; the second, to dedicate herself to the study of plants; the third, to leave her country and move to study in the United States.
In this way, afer schooling in Tellicery, she moved to Madras, where she obtained the bachelor´s degree from Queen Mary´s College and an honours degree in Botany from Presidency College in 1921.
Later, her university career took place at Queen Mary's College in the University of Michigan, where she majored in Botany and Cytology. In 1925, she earned a master's in science and six years later she received her Ph.D.
Therefore, she was the first indian woman to obtain a Ph.D.-in her case, botany, in the U.S., in 1931-and remains one of the few Asian women to be conferred an Honoris causa doctorate by her alma mater, the University of Miichigan. Her Ph.D. thesis, titled Edavaleth Kakkath Janaki Ammal (4 November 1897-15 February 1984) was the first Indian woman to earn a Ph.D., and in 1931, the first female scientist to become a member of the Indian Academy of Sciences, and probably the first female salary earner at the John Innes Institute and the first to be awarded a Padma Shri in 1977.

Therefore, she was the first indian woman to obtain a Ph.D.-in her case, botany, in the U.S., in 1931-and remains one of the few Asian women to be conferred an Honoris causa doctorate by her alma mater, the University of Miichigan. Her Ph.D. thesis, titled "Chromosome studies in Nicandra Physaloides", was published in 1932. During that time, she was living at Ann Arbor, in the Martha Cook building, an all-female residence [17].
In the early 1950s, she returned to India at the request of Jawaharlal Nehru, the country's prime minister after gaining independence from British rule in 1947. Nehru called her because India was recovering from the war that left India suffering famines throughout the country, with millions of people dying from malnutrition. Nehru wanted her to return to her country to organize and improve the botanical foundations of the country's agriculture.
In her work in India, she facilitated the identification of native plant varieties that could be crossed with the so-called "Saccharum" to produce a sugarcane crop more suited to the country's tropical environmental conditions. She also crossed dozens of plants to determine which Saccharum hybrids produced the highest sucrose content and developed several more hybrids by crossing various grass genera: Saccharum-Zea, Saccharum-Erianthus, Saccharum-Imperata and Saccharum-Sorghum. Above all, she began to use her influence to preserve endangered native plants.
Among the works she published, the following deserve to be highlighted: She entered the Indian Academy of Sciences in 1935 and the Indian National Academy of Sciences in 1957.
Throughout her personal career, she received several distinctions and recognitions: the University of Michigan conferred an honorary LLD on her in 1956 and the Government of India awarded her the "Sri Padma" award in 1957. India's Minister of Environment and Forests instituted and used her name for the National Taxonomy Award in 2000, intending to promote work of excellence in taxonomy and encourage young students and academics working in this field.
As an anecdote, which at first could seem humerous, but deep down it is not at all, it can be said that in her eagerness to preserve Indian plants, she was the only woman who in 1955 attended an international symposium in Chicago, ironically entitled "The role of man in changing the face of the Earth" [18].
The abbreviation "Jan.Ammal" is used to indicate Edavalath Kakkath Janaki Ammal as the authority on the scientific description and classification of plants.

Appendix B
To finish the article and to contextualize its content and give rise to possible comparisons, we include in this Appendix some references to other women who were either born or worked on the Asian continent in the first decades of the 20th century and who achieved important milestones in the course of their academic careers or in the exercise of their professional practice, although in disciplines other than Pharmacy and Chemistry. Sorted by date of birth, those born in or before 1930 were the following (see [19][20][21] for further information): Ogino Ginko (1851-1913) was the first registered female doctor to practise modern medicine in Japan.
