Every year, on the second Tuesday of October, is Ada Lovelace Day. It's an informally recognised international day celebrating the achievements of women in science, technology, engineering, and maths (STEM).

What is Ada Lovelace Day?

Ada Lovelace Day (ALD) celebrates women's achievements in science, technology, engineering, and maths (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls to pursue STEM careers and support women already working in STEM.

Who was Ada Lovelace?

Born in 1815, Ada Lovelace was an English mathematician and writer who is most famous for her collaboration with mathematician and inventor Charles Babbage on his early mechanical general-purpose computer, the Analytical Engine. Her approach of "poetical science" inspired her to inquire about the Analytical Engine (as evident in her notes), exploring the interaction between individuals and society with technology as a collaborative tool.

In 1843, Lovelace released a computer program to calculate Bernoulli Numbers, now considered the first of its kind. Although Babbage had previously created partial programs, Lovelace's program was the most comprehensive and intricate and was the first to be published.

Lovelace was the first person to envision the engine's potential for creativity. She articulated how it could go beyond basic number calculations and produce music and art with the appropriate programming and inputs. Her foresight into the possibilities of computing surpassed that of her contemporaries and went unnoticed for a hundred years.

How long has Ada Lovelace Day been observed?

Established in 2009, the event is now conducted every year on the second Tuesday of October. Aside from the day, Ada Lovelace has been commemorated in various ways, reflecting her influence as a pioneer in mathematics and computing:

  • Several buildings are named after her, including the Ada Lovelace Building at the University of Bristol, the Ada Byron Building at Zaragoza University, and the Ada Lovelace House in Nottinghamshire.
  • Google Doodles honoured her in 2012 and 2017, and a Google blog post celebrated her birthday.
  • In 2013, Ada Developers Academy was founded to help diversify the tech industry.
  • A BBC Radio 4 episode on "Great Lives" featured her in 2013.
  • British passports since 2015 include an illustration of Lovelace and Charles Babbage.
  • In 2018, Satellogic named a micro-satellite after her, and the U.S. Senate designated 9 October as National Ada Lovelace Day.
  • Trinity College Dublin commissioned a bust of her in 2020, and in 2022, a statue of her was unveiled in Westminster, London.
  • Nvidia named a GPU microarchitecture after her in 2022.
  • In 2023, the UK’s Royal Mint issued commemorative coins in her honour.
