Global recognition of women’s remarkable contributions to the fields of science, technology, engineering, and math (STEM). It is indeed to highlight the important work that women in STEM are now doing and to motivate the next generation of young girls to pursue careers in STEM.
Here are ten women who changed the tech world:
- Ada Lovelace: the first computer programmer in history
Lord Byron, a romantic poet, and his wife, Anna Isabella-Byron, were the parents of Ada Lovelace. Early on, her aptitude for mathematics was evident, and she developed a working connection with Charles Babbage thanks to her knowledge of and interest in machines. Babbage was the creator of the “Analytical Engine,” a complex machine that bore similarities to current computers but was never built. Ada is frequently referred to as the “world’s first computer programmer” as a result of her work on the project. Alan Turing drew inspiration from Ada Lovelace’s notes on the Analytical Engine when he was working on the first modern computer in the 1940s.
- Grace M. Hopper: The legendary computer scientist
Rear Admiral Grace M. Hopper, a renowned computer scientist and one of the first computer programmers to work on the Harvard Mark, is unquestionably well-known in the tech industry. Her efforts contributed to the creation of COBOL, a pioneering computer language that is still in use today. She is credited with discovering the first real computer glitch in the world in 1947 and with coining the proverb “it is frequently simpler to ask for forgiveness than to ask for permission.”
- Hedy Lamarr: WiFi’s Inventor
Hedy Lamarr was a self-taught inventor and actress who received a patent for her “secret communication system” in 1942. She had collaborated with composer George Antheil on its creation. During the war, this frequency hopping system was designed to throw radio-guided torpedoes off course, but the concept later became the basis for Bluetooth, Wi-Fi, and GPS, all of which are widely used today.
- Annie Easley: The NASA Rocket Scientist
NASA rocket scientist Annie paved the way for racial and gender diversity in STEM. She was one of only four black employees at the Lab when she was employed. 34 years later, she had made countless contributions to programs as a computer scientist, motivated people with her contagious enthusiasm for outreach initiatives, and dismantled barriers as an equal employment opportunity counselor. Easley’s crucial work on the Centaur rocket project while he was employed by NASA established the groundwork for upcoming space shuttle launches.
- Mary Wilkes: the first person to use a home computer
Mary used to create logic and program computers.
Her most notable work is the software she created for the LINC, one of the first interactive personal computer systems. She was the first person to use a home computer when she used a LINC in 1965, and her contributions are honored in the National Museum of Computing in Bletchley Park.
- Adele Goldberg: The GUI’s Inspiration
The original Apple computer was influenced by the programming language Smalltalk-80, which Adele helped create. According to reports, Adele described the choice to display Steve Jobs’ Smalltalk as a “kitchen sink giveaway.” She probably had a point. We use graphical user interfaces (GUI) on a daily basis thanks to the ideas Adele and her colleagues developed.
- Radia Perlman: The Internet’s Grandmother
Radia, known as the “Mother of the Internet,” developed the algorithm that forms the basis of the Spanning Tree Protocol (STP), which is a key component of the modern internet. Her work greatly influenced how networks self-organize and move data, and it established the fundamental guidelines for internet traffic.
Radia continues to work for Dell EMC as an engineer and computer programmer despite having given keynote addresses all around the world.
- Katherine Johnson: a mathematician for NASA
The first-ever US space voyage was a success thanks to Katherine’s trajectory analytic work for NASA. She also played a crucial role in later space flights, including John Glenn’s historic orbital flight. Her intricate manual computations. At Glenn’s request, Katherine manually entered the numbers that were programmed into the NASA computer for the trip. If she thinks they’re good, as he said, Katherine recalls, “then I’m ready to go.” President Obama presented her with the Presidential Medal of Freedom, the nation’s highest civilian honor when she was 97 years old.
- Karen Sparck-Jones: The Pioneer in Information Science
Karen was a pioneer in the field of information science, and some of her work has received the most citations.
She created the Inverse Document Frequency (IDF), a weighting factor used by web search engines to rate a page’s relevancy to a search query. IDF measures how significant a word is to a document. In 2007, she was awarded the prestigious Lovelace Medal!
- Elizabeth Feinler: The First Search Engine
Elizabeth oversaw the Network Information Center in California, a sort of “pre-historic Google,” from 1972 to 1989. The NIC created the initial “white pages” and “yellow pages” directories and was the first site to post resources and directories for the Internet. The domain naming structure that includes.com,.edu,.gov,.net and many more that we use so frequently today was also created by her group.
