Today we're marking the birth of a someone who is a hero to many of us at Google. Alan Turing was born 100 years ago into a world very different from our own—but he’s a founding father of every computer and Internet company today. In 1936, his paper “On Computable Numbers”  introduced two key concepts, “algorithms” and “computing machines," which now rank among the most important intellectual breakthroughs of the 20th century.

In the evolution of computing, all paths trace back to Turing—so we're proud to help commemorate and preserve his legacy. In 2010 we helped raise funds to preserve Turing's papers at Bletchley Park, and recently we’ve worked with curators at London’s Science Museum on their new exhibition “Codebreaker - Alan Turing’s Life and Legacy.” And of course, we couldn't let this occasion pass without a doodle. If you visit our homepage today, you'll find a simulation of his “Turing machine"—try your hand at programming it, and read more about Turing in our blog post:
