Early History of the Field

Computers weren’t always the sleek electronic machines we know and love. They weren’t even electric. Formerly, humans who performed computing tasks served as human “computers.” As machines replaced them, the tools gained the title. Any device that calculated numerical tasks was a “computer” in that it helped us compute things. Mechanical calculators appeared in the early 1600s, with a few different versions popping up in the following century. By the 1800s, they became powerful enough for use in office environments. Soon after, various forms of computation arose, such as the use of punch cards.

Computer Science from the 1990s to Now

In the early- to mid-1900s, computer science as a field of study grew its roots. The founding of the Watson Scientific Computing Laboratory by IBM and the close relationship with the associated university led to a focus on scientific research in the field. Thus, computer science, as an academic discipline, was born. Although it is relatively new, computer science has still contributed much to society. Following the Agricultural and Industrial Revolutions, it tends to mark the Information Revolution. That now puts us in the Information Age. More specifically, computer science has accomplished feats such as breaking the Enigma code, thus contributing to the end of World War II.

The history of the field is quite extensive and can’t possibly fit here. But, you’ll be able to find computer science articles in this category that further explore its development over time.
