Necessity is the mother of invention

International Women's Day is marked on March 8 every year and celebrates the cultural, social, economic, and political achievement of women around the world. Women of all walks of life have contributed to the development of science, technology, engineering, and medicine. Here are a few examples.

Sarah Goode (1855-1905), Inventor of the Folding Cabinet Bed

Goode was an entrepreneur who had many customers with very small apartments. She invented the folding cabinet bed to save space. It was a desk by day and a bed by night. When Goode registered her patent for the folding cabinet bed in 1885, she became the first Black American woman ever to get a United States Patent.

Her aim was to balance out the weight of the folding of the bed so that it could be easily lifted up, folded and unfolded, and to secure the bed on each side so that it would stay in place once it was folded. She provided supplementary support to the centre of the bed when it was unfolded.

Mary Golda Ross (1908-2008), engineer

Mary Golda Ross was the first known Indigenous female engineer, and the first female engineer in the history of Lockheed. She was Tsalagi (Cherokee). She was one of the 40 founding engineers of the Skunk Works project at the Lockheed Corporation. She worked at Lockheed from 1942 until her retirement in 1973. She is best remembered for her work on aerospace design – including the Agena Rocket program – as well as many "design concepts for interplanetary space travel, crewed and uncrewed Earth-orbiting flights, the earliest studies of orbiting satellites for both defense and civilian purposes."

Asima Chatterjee (1917-2006), chemist

Asima Chatterjee was a chemist who is greatly renowned for her contributions to organic chemistry and phytomedicine. She developed cancer medicines, anti-epileptic and anti-malarial drugs. She was the first woman to be named a Doctor of Science by an Indian university. She studied at the University of Calcutta and wrote several volumes of work on the medicinal plants of the Indian subcontinent. She was nominated by the president of India as a member of the Rajya Sabha.

Bette Nesmith Graham (1924-1980), Inventor of Liquid Paper

After she got divorced in 1946, Bette took a job as a secretary. Typewriters with carbon ribbons had just come into widespread use, and the old erasers that were previously used just smudged the paper. So, Bette, who had trained as an artist, came up with a mix of tempera paint to paint out her mistakes. Her boss never noticed the corrections. Soon other secretaries wanted a bottle of her special paint, and she realized that she had come up with something that would sell. When Liquid Paper (also known as Tippex and White-out) became a multi-million dollar company, she created two foundations to help women find new careers, especially unmarried mothers. The foundations also created college scholarships for older women and gave shelter and counselling to battered women. She described herself as a "feminist who wants freedom for myself and everybody else."

Fun fact: she was also the mother of Robert Michael Nesmith, the guitarist in the band The Monkees.

Frances Gabe (1915-2016), Inventor of the Self-Cleaning House

Before there was the Roomba, there was the self-cleaning house, with resin walls, waterproof furniture, no carpets, and a device in the ceiling that emits a jet of water, soap, and hot air to dry everything in the room after it has cleaned it. These labour-saving devices were invented by Frances Gabe, who went partially blind for 18 years after the birth of her first child, and grew up accompanying her architect father to work.

Lynn Conway (born 1938), inventor of new computer chip designs

Lynn Conway invented scalable, dimensionless design rules which hugely simplified chip design and design tools; and a new form of internet-based infrastructure for rapid-prototyping and short-run fabrication of large numbers of chip designs.

She was born in 1938 and transitioned to female in 1968. She was fired by IBM but went on to work for Xerox and DARPA.

She has five patents to her name, and retired to Michigan, USA. In Fall 2012, the Institute of Electrical and Electronics Engineers published a special issue of the IEEE Solid-State Circuits Magazine devoted to her career, including an autobiographical account of her career, and commentaries by the former Director of Engineering at HP, a Professor of EECS at U.C. Berkeley, and a Professor of Electrical Engineering and Biomedical Engineering at Columbia University.

Women's history 101

People often ask, why are there so few famous women writers, artists, scientists, and intellectuals?

They seem to be forgetting that, in previous centuries, it was rare for women to be educated. Women also often died younger due to infections contracted in childbirth.

Women were not allowed to attend university until the 1870s, and even then they were not allowed to graduate.

At the beginning of the 20th century it was very difficult for women to obtain a university education. In 1870 Emily Davies and Barbara Bodichon helped to set up Girton College, the first university college for women, but it was not recognised by the university authorities. In 1880 Newnham College was established at Cambridge University. By 1910 there were just over a thousand women students at Oxford and Cambridge. However, they had to obtain permission to attend lectures and were not allowed to take degrees.

Without a university degree it was very difficult for women to enter the professions. After a long struggle the medical profession had allowed women to become doctors. Even so, by 1900 there were only 200 women doctors. It was not until 1910 that women were allowed to become accountants and bankers. However, there were still no women diplomats, barristers or judges. (John Simkin)

The first social groups to routinely educate their daughters were the Unitarians and the Religious Society of Friends (Quakers), starting in the 1840s.

When women did succeed in producing literature or scientific research, quite often someone else got the credit for it, or their contribution or achievement was minimised. Even now, there are people who dispute that Ada Lovelace wrote programs for Babbage's calculating engine, and want to impute authorship of the Brontë sisters novels' to their brother Branwell. The scientific achievements of Lise Meitner, Cecilia Payne-Gaposchkin, Hedy Lamarr, Dorothy Hodgkin, Rosalind Franklin, Katherine Jones, Jocelyn Bell-Burnell, Caroline Herschel, and many others, are forgotten or sidelined. I did not learn about any of these women at school - I found out about them by researching on the internet, and reading blogposts from the Finding Ada project.

Many nineteenth-century female scientists and mathematicians were told that their scientific and mathematical activities were bad for their womb. Many were prevented from attending university, or not allowed to graduate, or made to work in a separate laboratory from the men.

The work of female writers, poets, artists, composers, and playwrights suffered a similar fate. Artemisia Gentileschi's paintings were attributed to her father. The Nobel Prize for Jocelyn Bell Burnell's discovery of pulsars went to her male PhD supervisor. The work of the women Pre-Raphaelite and Impressionist artists is largely forgotten.

A similar fate happens to Black & minority ethnic (BME) and LGBT scientists, authors, and heroes. And if you are a woman and BME and LGBT, then you are doubly or triply doomed to be sidelined. Just look at the marginalisation of Mary Seacole, Edward Carpenter, Goldsworthy Lowes Dickinson, and many another BME and/or LGBT person.

Even today, women's novels are marketed as less serious than novels by men. They also receive less reviews in serious journals. The novels of white male authors are taught on English literature courses; the novels of female authors are taught on courses of women's studies or women's literature. Maureen Johnson writes:

For much of history, women read the works of men. Every once in a while we see a woman cracking through, maybe changing her name, maybe hiding her work, or maybe breaking through the strength of her genius or good luck or both. Then we see a huge break in the early 20th century, a flux of brilliant women. Women start to climb into the bestseller charts, but not so much into the reading lists.

There is no doubt that women (despite massive disadvantages) have achieved great things in every field of artistic, literary, and scientific endeavour, but all too often, they are forgotten, sidelined, their achievements dismissed or diminished, their work not taught in schools or universities. The corpus of literature that is considered "the canon" is overwhelmingly by white men (usually dead white men, usually heterosexual). No-one is saying that these authors should no longer be taught; just that "the canon" should include women, BME people, and LGBT people.

Hedy Lamarr: an unlikely geek

In celebration of Ada Lovelace day 2010, here's a biography of someone you might not think of as a scientist and inventor:

Hedy Lamarr (born 1913)
Radio communications system

The Viennese-born femme fatale of 1930s and 1940s films is a lot more than just a pretty face.

The actress, whose real name is Hedwig Eva Maria Kiesler, immigrated to the United States during the early years of World War II. She is best known for sultry roles in such movies as "Ecstasy" and "Samson and Delilah," but she also coinvented a remote-controlled, anti-jamming communications system, a major contribution to U.S. defense technology.

According to Bethesda resident Anne Macdonald, author of a book about American women inventors and a patent-holder herself for a knitting machine, Lamarr learned about designs for military technologies while married to a wealthy Austrian arms dealer for three years. Soon after Nazi Germany invaded Austria in 1938, she left her husband and went to London, where Louis B. Mayer of MGM Studios changed her name and signed her up as his company's newest screen sensation.

In 1942, Lamarr and composer George Antheil received a patent for the communications system, which employed a feature known as frequency hopping. A radio signal, such as those used to direct torpedoes, would "hop" from one broadcast frequency to another at certain intervals. Therefore, if a receiver was not synchronized to receive the entire signal, the signal could not be "jammed" nor deciphered.

Lamarr's invention did not fit MGM's image of her as a glamorous movie star, and her creative side was a well-kept secret in Hollywood. Still, Lamarr was so passionate about helping the war effort that she seriously considered abandoning acting to join the National Inventors Council full-time.

Lamarr's system was never used during World War II, but long after her patent expired, the Sylvania Corp. adopted and further developed the idea.

The annual German Inventors' Day is held on her birthday, 9th November:

This lady is Hedy Lamarr, a Hollywood diva and inventor.
She is the prototype for the everyday life an inventor, not because she was an Edison, but simply because she was someone that tried to realise her idea.
She did not become rich or famous from her idea (as an actress she was already). Her invention however, the frequency hopping process is still in daily use and an integral process in our mobile phones.
Her birthday, 9th November, has been taken to represent all inventors and this Inventors' Day.
