Women have made remarkable achievements in science, technology, engineering, and mathematics (STEM). Throughout history, they have contributed significantly to uncovering the secrets of science, advancing human knowledge, and driving technological progress and innovation. Their role has been pivotal in shaping civilization across various fields. Here are some inspiring stories of women whose dedication and perseverance have made a global impact.
Marie Curie
Marie Curie, a Polish-born physicist and chemist, was the first woman to win a Nobel Prize and the first person to win it twice—in Physics and Chemistry. She was recognized for her groundbreaking discoveries of radioactivity, as well as the elements polonium and radium. Curie contributed to the development of X-rays and became the first female professor at the University of Paris.
In 1903, Marie Curie, along with her husband Pierre Curie and physicist Henri Becquerel, received the Nobel Prize in Physics for their joint work on radioactivity. Marie’s fascination with radiation began in 1895 after Wilhelm Conrad Roentgen discovered X-rays and Henri Becquerel discovered that uranium emitted invisible radiation. Marie studied uranium rays using electrical techniques developed by her husband, eventually isolating polonium and radium. For her outstanding contributions to chemistry, she received her second Nobel Prize in Chemistry in 1911.
Ada Lovelace
Born on December 10, 1815, in London, Ada Lovelace was the daughter of the poet Lord Byron and mathematician Annabella Milbanke. She is considered the world’s first computer programmer. In the 19th century, decades before the invention of the modern computer, she wrote the first algorithm intended for Charles Babbage’s “Analytical Engine.”
Lovelace envisioned computers going beyond mere calculations to tasks such as music and graphics. She translated and enhanced Babbage’s work, creating the first computer programming system. Her detailed notes included a method for using the machine to compute sequences of numbers—what we now recognize as the first computer program. Babbage referred to her as the “Enchantress of Numbers” for her mathematical talent and visionary thinking.
Katsuko Saruhashi
Katsuko Saruhashi (1920–2007) was a Japanese geochemist who pioneered methods for measuring carbon dioxide concentrations in seawater. Born in Tokyo, she graduated from the Imperial Women’s College of Science and began working at the Geochemistry Laboratory of the Observatory with her mentor Yasu Miyake.
In 1950, she began studying CO2 levels in seawater—a topic not considered significant at the time—and developed her own measurement techniques. She earned her PhD in Chemistry in 1957, becoming the first woman to do so in Japan. Saruhashi’s “Saruhashi Table” provided the world’s first accurate scientific method to measure oceanic CO2, influencing climate change studies. Later, she also studied nuclear waste, helping strengthen marine regulations for nuclear experiments.
Elizabeth Blackburn
Elizabeth Blackburn is an Australian-American biologist and professor at the University of California, San Francisco. She received the 2009 Nobel Prize in Physiology or Medicine along with Carol Greider and Jack Szostak for their discovery of the telomere structure—protective caps at the ends of chromosomes—and the enzyme telomerase.
Her research on telomeres and telomerase has been crucial in understanding cell division, DNA replication, cancer therapies, aging, and the biological effects of lifestyle on longevity. Blackburn emphasizes rigorous scientific methodology, ensuring all conclusions are data-driven and precise.
These women demonstrate that determination, vision, and persistence can break barriers and transform the world of science, leaving a lasting legacy for generations to come.
