In 1843, Ada, Countess of Lovelace, contributed to the field of computing by publishing "Notes" on Charles Babbage's Analytical Engine. This work is considered one of the first instances of computer programming, as she described how the machine could be instructed to perform various operations. Her insights laid the groundwork for future developments in computing and highlighted the potential of machines to execute complex calculations.

In 1847, George Boole made a significant advancement in logical reasoning by introducing an algebraic approach to understand truth values, which later became known as Boolean logic. By the 1890 census, this logical framework helped in efficiently tabulating data, showcasing the practical applications of Boole's theories. Walter Isaacson's book "The Innovators" connects these historical milestones, illustrating how a collaboration of inventors and thinkers helped shape the digital revolution.
