"We may say most aptly that the Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves. . . ." - so wrote Ada, Countess of Lovelace, in 1840. She invented some of the earliest computer programming concepts. You can read more about her here.

Today is Ada Lovelace Day, and bloggers are writing about women they admire in technology and science. I drew a sketch of Lovelace, based on a painting of her I found online. Today is also my mother's birthday - you can see some of her recent work here. Her first career was as a scientist, and since I admire her more than words can say, Sarah Hollis Perry is the woman I celebrate today. Happy Birthday, and may you continue to inspire and encourage us.


Hi Elizabeth,
I'am very impressed how long you are blogging!
I like your sketchbook, too.
