Randall Munroe is the creator of the webcomic xkcd and bestselling author of What If?, Thing Explainer and xkcd: Volume 0. Randall was born in Easton, Pennsylvania, and grew up outside Richmond, Virginia. After studying physics at Christopher Newport University, he got a job building robots at NASA Langley Research Center. In 2006 he left NASA to draw comics on the internet full time, and has since been nominated for a Hugo Award three times. The International Astronomical Union recently named an asteroid after him: asteroid 4942 Munroe is big enough to cause mass extinction if it ever hits a planet like Earth.
