Innovators: Ada Lovelace

Episode Summary

Ada Lovelace was born in London, England in 1815 to Lord and Lady Byron. Her mother, Lady Byron, was a mathematician who wanted to suppress Ada's imagination, so she ensured Ada was educated in logic, math, and science. This led Ada to develop a love of numbers. At age 17, Ada met mathematician Charles Babbage, who showed her a prototype for his difference engine, an early mechanical calculator. This began a lifelong correspondence between them about math and computing. In 1842, when Babbage began plans for an analytical engine, considered the first computer, Ada became its interpreter. She published notes on the engine, including the first computer program - an algorithm to calculate Bernoulli numbers. Her notes demonstrated the machine's potential beyond pure calculation, such as for music and art. She envisioned many of the capabilities of modern computers. Ada offered to be the public face of the analytical engine, but Babbage rejected her because of sexist views about women's abilities. Although not fully recognized during her lifetime, Ada Lovelace's contributions to computing are now considered pioneering. She died of cancer in 1852 at age 36. In the 1980s, the U.S. Department of Defense named a software language "Ada" in her honor.

On LinkedIn, important conversations are happening around what it means to be a professional. Right now, LinkedIn members are talking about things like needing more flexibility around where we work, how we work, and even taking time away from work to focus on family or mental health. Because those things should not stunt career development and growth. Instead, they should enhance it as we show up on our own terms. Professional is ours to define. And your authentic self is your professional self. Post your truth. Show the world the authentic professional you. And join the conversations redefining professional on LinkedIn. LinkedIn, welcome professionals. Hello, from Wonder Media Network, I'm Jenny Kaplan, and this is Womanica. This month, we're highlighting innovators, women who helped shape the world we live in today, from inventors to activists. Today's innovator is known as the first computer programmer. Despite living during a time when women were not considered scientific thinkers, her contributions to computer science are indispensable and indisputable. Let's talk about Ada Lovelace. She was born on December 10th, 1815 in London, England, to Lord and Lady Byron. Lord Byron was a famous poet, and Lady Byron was a mathematician. The two were opposites. Lady Byron was a woman of logic and science. Lord Byron was a man of imagination and romance. Shortly after Ada's birth, she was born in London, England. Shortly after Ada's birth, Lady Byron left and moved Ada out of their family home. In an effort to keep Ada from inheriting her father's fanciful behaviors, Lady Byron educated her daughter in arithmetic, music, and French. She wanted to suppress Ada's imagination, fearing that it was dangerous and potentially destructive. ["The Star-Spangled Banner"] Lady Byron provided Ada with the best tutors. In turn, Ada fell in love with numbers. One of her tutors was Mary Somerville, a scientist and writer. Mary was responsible for introducing Ada to two very important people in her life, her husband and her mentor. When Ada was 17, she made her debut into society. At the party, Mary introduced Ada to the renowned mathematician Charles Babbage. Charles captivated Ada with his most recent invention, a two-foot-high brass mechanical calculator called the difference engine. After seeing the prototype in action, Ada began an almost two-decade-long correspondence with Charles. When Ada was 19 years old, she married William King. Three years later, William became an Earl and Ada became the Countess of Lovelace. William and Ada had three children together and remained married until her death. But married life did not keep Ada from her first love, math. In 1842, Charles Babbage had set his sights on a new invention called the analytical engine. Ada was once again taken with the idea and became its interpreter. Although the machine was never built, the plans for it are believed to be the world's first digital computer. It had all of the necessary components and features of a modern-day computer. With the hopes of securing financing for the project, Charles had an Italian mathematician write a paper on the machine. The paper was published in a Swiss academic journal in October of 1842. The next year, Ada published the English translation with her own notes. While the original paper was about 8,000 words, Ada's version was 20,000. Ada's notes are considered her greatest contribution to computer science. They went beyond simply describing how the engine worked. Ada explained that this machine would be able to understand symbols and could be used to create music and art. She also included a plan for using the analytical engine to calculate Bernoulli numbers. This plan is known as the first computer program. Ada had developed a personal philosophy that she called poetical science, a combination of science and imagination. She saw math and logic as creative and imaginative. Ada envisioned a world in which computers could perform faster and more accurate analyses than humans. She imagined the modern-day, general-purpose computer a century before its creation. In August of 1843, Ada wrote Charles a letter offering to be the public face of the machine. In modern-day terms, Charles was the Steve Wozniak of Apple. He needed Ada to be a Steve Jobs. But because of Charles' sexist view of women, he couldn't see Ada as more than an interpretus of his work. He rejected her offer, and the evolution of the computer was delayed by a century. ["The Although Ada's contributions are highly regarded today, this was not always the case. Years after her publication, scholars challenged the significance of Ada's work. They believed her talents were blown out of proportion. As the importance of computer programming grew, Ada's work was a huge opportunity, even if it's a small one." Ada died on November 27, 1852, at the age of 36, from uterine cancer. ["The In 1980, the U.S. Department of Defense developed a software language called Ada. It brought together several different programming languages. Founded in 2009, the second Tuesday of every October marks Ada Lovelace Day.

Tune in tomorrow for another episode about an innovator. Talk to you then. SPEAKER_04: Hey there. It's Jenny with some exciting news. Womanika is hosting our first in-person event since the pandemic started. In honor of Women's History Month, we're teaming up with New York's first women-owned brewery, Talaya, to host a Womanika-themed trivia night. We'll have specialty cocktails and beer, plus prizes for the top three teams. We'll also be joined by the board chair of the ERA Coalition, Kimberly Peeler Allen, and ERA Coalition staffer Vivian Pong, to talk with us about the work they do. The event is free to attend, and a link to sign up can be found in the show notes or on the Womanika Instagram. So grab your friends, brush up on your history, and join us at the Talaya Taproom on Wednesday, March 9th at 7 p.m. See you there.
