Ada Lovelace was an English mathematician and writer in the 1800s who is considered the first computer programmer for her work on Charles Babbage's proposed mechanical general-purpose computer called the Analytical Engine. The Analytical Engine was designed by Charles Babbage to be a mechanical computer that could be programmed to compute arbitrary formulas and sequences, and Ada Lovelace wrote the first computer program for it, which was published alongside an article on the Analytical Engine.

2. WHO WAS ADA LOVELACE?
(UK 1852-1815)
Augusta Ada King, Countess of
Lovelace was an English
mathematician and writer, chiefly
known for her work on Charles
Babbage's proposed mechanical
general-purpose computer, the
Analytical Engine. [YT 4:26]
She is considered to be the first
computer programmer.

5. WHAT IS THE ANALYTICAL
ENGINE?
The Analytical Engine was a
proposed mechanical general-
purpose computer designed by
English mathematician and
computer pioneer Charles
Babbage. It was first described in
1837 as the successor to
Babbage's difference engine, a
design for a simpler mechanical
computer. [YT 13:26]
