I would say his mother. Some would argue that it was his father, but because his mother gave birth to him, it makes sense that it was her. On a serious note, what do you mean? Do you mean programming LANGUAGE?

Lady Ada Augusta Lovelace
She was the first "programmer".
As Ada Lovelace is often credited as the first computer programmer (in 1843, by the way) it would seem fair to credit Charles Babbage's Analytical Engine as the first machine for which a programming language was developed. That said, modern third generation programming languages weren't invented until Grace Murray Hopper designed COBOL in 1959. COBOL was not developed on any machine. It was specified to be machine independent and was simultaneously developed for both IBM and RCA computers in 1960.
Yes, Ada Lovelace is considered to be a mathematician. She is often regarded as the world's first computer programmer for her work on Charles Babbage's Analytical Engine, where she developed an algorithm that could be programmed into the machine. Lovelace's contributions to the field of mathematics and computing have had a lasting impact.
