Dev Hynes was born in Houston, Texas, and raised in Ilford, East London. He was educated at the Chadwell Heath Foundation School, now known as Chadwell Heath Academy. He has resided in New York since 2007. The name 'Lightspeed Champion' comes from a series of comic strips Hynes drew as a teenager in his school mathematics books. Hynes was voted the 49th 'coolest person in rock' in NME's 2007 Cool List, jumping to position 20 in the following year's list. From their formation in 2004 until their break-up in 2006, Hynes was a member of the band Test Icicles, playing guitar, synth, and occasionally performing vocals. They released only one full-length album (For Screening Purposes Only) in 2005.
