Marie Curie, born Maria Salomea Skłodowska in Warsaw, Poland, on November 7, 1867, was a physicist and chemist renowned for her groundbreaking research in radioactivity. She was the first woman to win a Nobel Prize and only the fourth person (and second woman) to win a Nobel Prize across two different disciplines, physics and chemistry. Marie's upbringing revolved heavily around education, she attended illegal underground classes during the repressive period of Russian occupation. Despite this setback, she obtained her degrees in mathematics and physics at the University of Paris-Sorbonne. It was here where she met her future husband, Pierre Curie, who would later become her scientific collaborator.

Together they discovered two new chemical elements, radium, and polonium, and coined the term radioactivity. Marie earned international notoriety for being the first woman to receive a doctorate in science from Sorbonne University and winning her first Noble Prize with Pierre for their work on radioactive substances, an accomplishment not seen before or since. After Pierre's passing, Marie became a professor at Sorbonne University, becoming one of France's leading researchers into radioactivity while also campaigning for women's rights within academia.

In 1911, Marie received a second Noble Prize—this time alone—for her discovery of two new elements, radium, and polonium, which ignited a global interest in studying radioactivity. During WWI, Marie set up mobile x-ray stations across battlefields in France, so wounded soldiers could be effectively treated, thus establishing x-ray therapy as an essential medical tool still used today.

Marie is one of the scientist's most influential pioneers—demonstrating that hard work can pay off despite any obstacles one may face. Her name lives on through innumerable worldwide monuments, awards, and scholarships that continue to inspire women to pursue scientific fields regardless of gender barriers or personal restrictions.

Ada Lovelace

Ada Lovelace is widely considered the world's first computer programmer. Her influence in computing and mathematics was so seminal that she became known as the "first lady of computers." Ada Lovelace, born Augusta Ada King, was born on December 10, 1815, in London. Raised by her mother and educated mainly at home, with a focus on mathematics and science, she developed a passion for these subjects at an early age. She also had an interest in literature and poetry, two fields of study encouraged by her mother's side of the family, who had many notable intellectuals within their ranks, such as Romantic poet Lord Byron (her father).

From an early age, Ada demonstrated great aptitude for mathematics, but it wasn't until she became acquainted with Charles Babbage that her true potential began to shine. She wrote programs for his Analytical Machine, undoubtedly becoming the world's first computer programmer through this process. Her notes are some of the most comprehensive ever written on Babbage's machine and the "the earliest real example of a computer program in action." Ada's work included ideas about how codes could be created for machines to handle letters and symbols instead of numbers, something revolutionary for its time and not fully exploited until almost 100 years later with the invention of the modern computer. In addition to this groundbreaking contribution, Ada devised theories about artificial intelligence and the possibility for machines to think for themselves; these remain largely unproven to this day but are nevertheless attributed to her forward-thinking nature regarding computing technology.

Ada's lasting legacy lies in popularising the underpinning concepts that still drive progress in computing today: "a fusion between humans and machines." By approaching computing from both theoretical and practical perspectives, she demonstrated that machines could take input from a human user or scientist, manipulate it according to set algorithms or rules within code, then produce a specific output or result—setting up our modern digital infrastructure step by step through her pioneering work over 150 years ago.

Grace Hopper, born December 9, 1906, in New York City, was an American computer scientist and United States Navy Rear Admiral. She is often referred to as "the first lady of software" due to her pioneering work in programming. Her career spanned almost six decades, from the 1940s until her death on January 1, 1992. Hopper took inspiration from mathematics from a young age and studied at Vassar College, graduating in 1928 with a bachelor's degree in mathematics and physics. She then continued her studies at Yale University, earning a master's degree and later a Ph.D. in mathematics in 1934.

After receiving her Ph.D., Hopper became a professor of mathematics at Vassar College until 1942, when she joined the Women Accepted for Volunteer Emergency Service (WAVES) during WWII. It was while working with WAVES that Hopper began researching computers, and she became one of the first programmers of the Harvard Mark I computer, arguably one of the earliest computers ever built. In 1959, Hopper introduced the world to Cobol—or Common Business Oriented Language—which revolutionized programming language and is still used in some cases today. The same year she also released her influential book "Understanding Computers and Computation," which detailed many concepts still used today, such as optimization problems and memory storage.

In addition, Hopper worked on other significant projects, such as Compiler language development and time-sharing systems. Hopper's incredible accomplishments are globally recognized with numerous awards, including the National Medal of Technology from President Reagan (1991), and IEEE Computer Pioneer Award (1994), among others.  Additionally, in 2016 Google honored Hopper with a Doodle celebrating what would have been her 110th birthday. These accolades speak volumes about the importance of Hopper's legacy; even today, she continues to influence computing science across the globe, proving that there will always be room for pioneering women like Grace Hopper.
