On the second Tuesday of October each year, we celebrate Ada Lovelace Day (ALD), founded in 2009 by journalist Suw Charman-Anderson to honor the many women in STEM (findingada.com); but you might be thinking, who in the world is Ada Lovelace? And why her? English mathematician Augusta King, Countess of Lovelace, more popularly known as Ada Lovelace, made her mark in history by publishing one of the first algorithms to be executed by a machine. And though the term computer didn’t exist in her time, this makes her the first published programmer.
