Ada Lovelace is credited as being the first computer programmer, but a lot has changed since she wrote the first computer algorithm in 1843. Over the decades that followed punch cards and vacuum tubes dominated the computer landscape until transistors paved the way for computer chips in 1956. Jack Kilby made the first integrated circuit out of transistors just two years later, propelling computer science forward at rocket speed for the next several decades. Now we have computers in our pockets more powerful than the first space shuttle just 50 years later. Learn more about the evolution of computer science from this infographic!
