3. Hedy Lamarr: The Actress Who Invented Frequency-Hopping Technology
Hollywood star Hedy Lamarr was more than a glamorous actress; she was also a talented inventor. During World War II, she co-invented a frequency-hopping technology with composer George Antheil to help the U.S. military prevent enemy interception of radio-controlled torpedoes. Although initially overlooked, their invention became the foundation for modern wireless communication technologies, including Wi-Fi, GPS, and Bluetooth.

Legacy: Hedy Lamarr’s contributions to technology weren’t fully recognized during her lifetime, but today, she is celebrated as a pioneer in communications technology.
4. Wang Zhenyi: The Chinese Astronomer Who Challenged Tradition
In the 18th century, Wang Zhenyi defied social norms in China by pursuing her passion for science and mathematics. She educated herself and conducted experiments, writing papers on eclipses, planetary movements, and trigonometry. Her work challenged the conventional wisdom of her time and contributed to a deeper understanding of astronomy and physics, despite living in an era where women were discouraged from academic pursuits.
Legacy: Wang Zhenyi’s contributions have inspired Chinese scholars and are a testament to the role women have played in the advancement of science in China.
5. Rosalind Franklin: The Unsung Hero of DNA Discovery
Rosalind Franklin, an English chemist and X-ray crystallographer, made one of the most crucial contributions to the discovery of DNA’s double-helix structure. Her famous “Photo 51” provided key insights into DNA, though credit largely went to James Watson and Francis Crick, who used her findings without proper recognition. Franklin’s groundbreaking work on DNA, as well as her research on viruses, laid the foundation for much of modern genetics.
Legacy: Although her contributions were initially overshadowed, Rosalind Franklin is now recognized as a central figure in molecular biology and genetics.
