Well talking about the first programmer, it was a female. To know the first programmer in history, let’s look at the history of computer because then it will be easy to understand the whole thing.
Everyone here knows that Charles Babbage (an English mathematician) is known as the father of modern computer.
In 1834, Babbage designed an analytical engine -first programmable digital mechanical computer that is known as the origin of modern computer.
Lady Ada Lovelace (an English mathematician and writer) is known as the first computer programmer and the reason behind this is that she was the strong supporter of Babbage’s work and she wrote many of the operating instructions for the experimental machine designed by Babbage.
Lady Ada Lovelace also presented some of the key elements of programing and program designs. She is chiefly known for mathematics and computing.
