Born in 1815, Ada Lovelace is widely regarded as the world's first computer programmer. The daughter of the famous poet Lord Byron, Lovelace was introduced to mathematics at an early age by her mother, who wanted to steer her away from her father's artistic tendencies. Lovelace's talent for mathematics was quickly recognized, and she went on to study with some of the leading mathematicians of her time.
In 1842, Lovelace translated a paper by Italian mathematician Luigi Menabrea on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. In the process, she added her own notes and annotations, which were three times longer than the original paper. Lovelace's notes included the first algorithm ever intended for processing by a machine, making her the world's first computer programmer.
Lovelace's contributions to the field of computing were not recognized during her lifetime. She died in 1852, at the age of 36, after a long battle with cancer. It was not until the 1950s, when computer programming was becoming a recognized field, that Lovelace's work was rediscovered and her place in history as a computing pioneer was secured.
Grace Hopper was an American computer scientist and US Navy rear admiral who made significant contributions to the development of computer programming languages. Hopper earned a PhD in mathematics from Yale University in 1934 and joined the US Navy Reserve in 1943, where she was assigned to the Bureau of Ordnance Computation Project at Harvard University.
In 1952, Hopper developed the first compiler, a software tool that translates programming languages into machine code. This was a significant step towards the development of high-level programming languages and the democratization of computer programming. Hopper's work laid the foundation for the development of Cobol (Common Business-Oriented Language), a high-level programming language that was widely used in business and government applications.
Hopper's contributions to the field of computing were not limited to her technical achievements. She was a gifted teacher and communicator, and she played a key role in popularizing the use of computers in business and government. Hopper was awarded the Presidential Medal of Freedom in 1986, in recognition of her contributions to the field of computing.
Katherine Johnson is an African-American mathematician who made significant contributions to the field of aeronautics and space travel. Johnson was one of a group of African-American women who worked as 'human computers' at NASA's Langley Research Center in Virginia during the 1950s and 1960s. These women performed complex calculations by hand, long before the advent of electronic computers.
Johnson's work was critical to the success of several major space missions, including John Glenn's historic orbit of the Earth in 1962. Glenn famously refused to fly until Johnson had personally checked the calculations for his mission. Johnson's contributions were recognized in 2015, when she was awarded the Presidential Medal of Freedom by President Barack Obama.
Johnson's story was brought to the forefront of popular culture by the 2016 film 'Hidden Figures', which told the story of the African-American women who worked as 'human computers' at NASA. Johnson's legacy as a trailblazer and role model for women in science and engineering is a lasting tribute to her achievements and contributions to the field of computing.
Hedy Lamarr was an Austrian-American actress and inventor who made significant contributions to the field of wireless communication. Lamarr was born in 1914, and after a successful career as an actress in Hollywood, she turned her attention to inventing. In 1942, Lamarr and composer George Antheil developed a frequency-hopping signal technology that allowed radio-controlled torpedoes to avoid detection and jamming.
The technology developed by Lamarr and Antheil was not adopted by the US Navy until the 1960s, but it laid the foundation for the development of modern wireless communication technologies, including Wi-Fi, Bluetooth, and GPS. Lamarr and Antheil were posthumously awarded the Electronic Frontier Foundation Pioneer Award in 1997, in recognition of their contributions to the field of wireless communication.
Lamarr's story is a testament to the power of innovation and the need to recognize and honor the contributions of women in science, technology, engineering, and mathematics (STEM) fields. Despite facing significant barriers and discrimination, these pioneering women persevered and made lasting contributions to the field of computing and beyond.
