Lesson 1: Women who changed science
A global timeline of discoveries and the women behind them.
Start here
Rita Levi-Montalcini was barred from her university laboratory, so she built one in her bedroom out of sewing needles and a watchmaker's forceps. The work she did there won a Nobel Prize.
In this lesson you will
- Describe contributions made by women in neuroscience and related STEM fields.
- Explain how access and opportunity shaped who was able to contribute.
- Connect a historical discovery to a question researchers still study today.
Science is often taught as a list of findings, which makes it easy to forget that findings come from people working under particular conditions. Many of the women in this lesson made their discoveries while excluded from laboratories, salaries, or credit. Their work is now standard textbook science.
Excluded, and still contributing
For most of modern scientific history, women were formally or informally barred from universities, laboratories, professional societies, and authorship. The contributions in this lesson happened despite those conditions — which tells you both what was achieved and what was likely lost.
Discovery is global
Important work came from Italy, Norway, India, the United States, Iran and beyond. Neuroscience and its neighbouring fields were never the property of one country or one kind of person, even when the published record made it look that way.
Credit is part of the story
Some discoveries were named after supervisors rather than the people who made them. Historians call this pattern the Matilda effect: the systematic under-recognition of women's scientific contributions. Recognising it is part of reading the history accurately.

1939
Bedroom laboratory, wartime Italy
Barred from academic work by Italy's racial laws, Levi-Montalcini ran experiments on nerve growth at home. Her later discovery of nerve growth factor — a signal that tells neurons to survive and extend — earned the 1986 Nobel Prize and underpins research on nerve repair today.

Match each contribution to the scientist. Every answer includes a short explanation.
Item 1 of 4
Discovered nerve growth factor, a signal that keeps neurons alive and growing.
Predict: what happened to the credit?
Make a prediction, then reveal the historical pattern.
In the mid-twentieth century, when a woman researcher made a major discovery in a laboratory she did not lead, what most often happened to the public credit?
Real-world connection: the record is still being corrected
Universities, journals and organisations such as UNESCO now run projects to document women's contributions that went unrecorded. When a textbook adds a name, that is not a courtesy — it is a correction to the scientific record.
Three Key Takeaways
- 1Women made foundational contributions to neuroscience and STEM, often while excluded from formal science.
- 2Discovery has always been global, including major work from South Asia.
- 3Credit was distributed unevenly, so the historical record needs active correction.
