John Green

John Michael Green (born August 24, 1977) is an American author and YouTuber. His books have more than 50 million copies in print worldwide, including The Fault in Our Stars (2012), which is one of the best-selling books of all time. Green's rapid rise to fame and idiosyncratic voice are credited with creating a major shift in the young adult fiction market. Green is also well known for his work in online video, most notably his YouTube ventures with his younger brother Hank Green.

Born in Indianapolis, Indiana, Green was raised in Orlando, Florida, before attending boarding school outside of Birmingham, Alabama. He attended Kenyon College, graduating with a double major in English and religious studies in 2000. Green then spent six months as a student chaplain at a children's hospital. He reconsidered his path and began working at Booklist in Chicago while writing his first novel. His debut novel Looking for Alaska (2005) was awarded the 2006 Michael L. Printz Award. While living in New York City, Green published his second novel, An Abundance of Katherines (2006). Starting on January 1, 2007, John and his brother Hank launched the Vlogbrothers YouTube channel, a series of vlogs submitted to one another on alternating weekdays; the videos spawned an active online-based community called Nerdfighteria and an annual telethon-style fundraiser called Project for Awesome, both of which have persisted and grown over time.
