Augusta Byron


 Major Contribution: Wrote the first computer program and contributed to the work of Charles Babbage.


Ada Lovelace was an English mathematician and writer chiefly known of rher work on Charles Babbage's early mechanical general-purpose computer, the Analysical Engine.

She understood the plans for the device as well as Babbage but was better at articulating its promise and potential.

 “Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”


She correctly perceived the engine as what is not referred to as a general-purpose computer. It was suited for "developing and tabulating any function whatever. . . the engine is the material expression of any indefinite function of any degree of generality and complexity." Her notes anticipated future developments.


Ada’s notes on the Analytical Engine include what is recognized as the first algorithm intended to be processed by a machine. Because of this, she is often considered the world's first computer programmer. The computer language Ada , was named after Ada Lovelace.


This type of analysis was a conceptual leap from previous ideas about the capabilities of computing devices, and foreshadowed the capabilities and implications of the modern computer. Thus, Ada Lovelace was the visionary half of the team that helped create the modern computer.
