The unsung architects of STEM: Women who changed the world without recognition

Figures like Marie Curie and Ada Lovelace are widely celebrated, but many other women in science, technology, engineering, and mathematics made groundbreaking contributions that often went unrecognised. These pioneers reshaped medicine, space exploration, mathematics, and technology, quietly transforming the world. (unsplash)

Chien-Shiung Wu (Physics): A brilliant experimental physicist, Wu played a key role in disproving the law of conservation of parity, a discovery that revolutionized particle physics. Although her male colleagues received the Nobel Prize, Wu’s experiment made the breakthrough possible. (wikimedia commons)

Dr. Asima Chatterjee (Organic Chemistry): An Indian chemist whose research led to important anti-malarial and anti-epileptic drugs. Her work significantly advanced medicinal chemistry in India and earned her some of the country’s highest scientific honours. (wikimedia commons)

Hedy Lamarr (Technology and Engineering): Better known as a Hollywood actress, Lamarr co-invented a frequency hopping communication system during World War II. Her innovation laid the groundwork for modern Wi-Fi, Bluetooth, and GPS technology. (wikimedia commons)

Katherine Johnson (Mathematics): A NASA mathematician whose calculations were essential to early U.S. space missions, including John Glenn’s orbit around Earth. Her precise work helped ensure astronaut safety at a time when computers were still new. (wikimedia commons)

Mary Anning (Paleontology): A self taught fossil hunter in 19th century England, Anning made pioneering discoveries of prehistoric marine reptiles. Her finds contributed significantly to early understanding of extinction and Earth’s ancient history. (wikimedia commons)

Rosalind Franklin (Chemistry and Molecular Biology): Franklin’s X-ray diffraction images were crucial to understanding the double helix structure of DNA. Her work laid the foundation for one of the greatest scientific discoveries of the 20th century, though she did not receive equal credit during her lifetime. (wikimedia commons)
