ALD 2009's Pledge

Ada Lovelace Day started with a simple promise on Pledgebank:

"I will publish a blog post on Tuesday 24th March about a woman in technology whom I admire but only if 1,000 other people will do the same."
— Suw Charman-Anderson

Tuesday 12 October 2021 is Ada Lovelace Day, an international day celebrating the achievements of women in science, technology, engineering and maths.

With thanks to our partners

Ada Lovelace Day is dependent on the generosity of its partners, volunteers and supporters for survival. If you would like to sponsor Ada Lovelace Day, please get in touch. We would like to thank the following organisations for their support of Ada Lovelace Day and women in STEM.
