Ada Lovelace is considered the first computer programmer. Even though she wrote about a computer, the Analytical Engine, that was never built, she realized that the computer could follow a series of simple instructions, a program, to perform a complex calculation.

the Analytical Engine
She also added thousands of words of her own notes to the paper. Lovelace realized that the Analytical Engine could carry out an extensive sequence of mathematical operations. The example she wrote of one such sequence—how to calculate Bernoulli numbers—is regarded by computer historians as the first computer program.

English mathematician Ada Lovelace, the daughter of poet Lord Byron, has been called “the first computer programmer” for writing an algorithm for a computing machine in the mid-1800s.

Ada Lovelace
About a century before Konrad Zuse designed the first programmable computing machine, in the 1840s, Ada Lovelace wrote the first computer programme in the world.

Charles Babbage
Charles Babbage, who was born in 1791, is regarded as the father of computing because of his research into machines that could calculate. Babbage’s Difference Engine Number 1 was the first device ever devised that could calculate and print mathematical tables.

Practical Universal Computing Machines
Turing himself referred to computers (in the modern sense) as ‘Practical Universal Computing Machines’.

1840s
In the 1840s, Ada Lovelace became the first computer programmer, inspite of the fact that the Analytical Engine (the computer that she designed the programs for) wasn’t ever manufactured. She was also the first person to suggest that a computer could be more than just an oversized calculator!
