Frankie Knuckles, the DJ and producer who was known as the 'Godfather of House', has died suddenly at his Chicago home from diabetes-related complications.
He was 59 and had DJed in London just two days before his death [Monday March 31].
The Bronx-born Knuckles began to DJ in New York in the early 1970s but later moved to Chicago where his pioneering work helped to make house music a global phenomenon.
Among his most famous tracks are Your Love and The Whistle Song.
As a producer and remixer he worked with Michael Jackson, Diana Ross, Chaka Khan and En Vogue, among many others.
In 2004, the City of Chicago renamed part of Jefferson Street near the legendary club Warehouse - where the term 'house music' is believed to have originated - Frankie Knuckles Way. In 2005, Knuckles was inducted into the Dance Music Hall of Fame.
