Today we commemorate #InternationalWomensDay by recognising one of our favourite 19th Century Mathematicians, Countess Ada Lovelace.

In 1995 the Powerhouse Museum acquired its specimen piece of Charles Babbage’s Difference Engine No1. Included in the auction lot were 2 letters addressed to Charles from Ada Lovelace. Later when the acquisition brought us in to contact with Charles’ descendants in Australia we acquired from them, among other items, a small envelope addressed to Babbage containing the calling card of Countess Lovelace.

Hand written on the back is the mysterious and tantalising “Very Interesting”. We are delighted to have these items in the Museum’s collection, evidence of Charles’ and Ada’s association.

From today’s perspective the culmination of this partnership is the much repeated writing of the ‘first computer programme’ by Ada in her description of Babbage’s Analytical Engine. The paper, written in 1843, is a translation from the French of a paper on the Analytical Engine written by Italian engineer (and later Italian Prime Minister) Luigi Menabrea. Menabrea had reported a lecture by Babbage on his Analytical Engine in Turin. But Ada’s paper included extensive notes of her own and incorporated a table or plan which shows how to set up the Analytical Engine to generate the numbers of the Bernoulli series - Matthew Connell, 2010.
