A memorial service for Frankie Knuckles was took place in Chicago yesterday, with family and friends of the late, great "Godfather of House" paying their respects to the musical icon. They also received a special delivery from the White House in the form of a heartfelt message from the President and First Lady of the United States.

DJ David Morales posted the Obamas' letter this morning, along with his appreciation for the Obamas support. "Frankie's memorial service was emotionally special. To have his friends, family and the Governor speak about Frankie goes to show the impact he has had on people. You know you're a TRUE LEGEND when u get one of these…."

From the Obamas:

We were deeply saddened to learn of Frankie's passing, and we extend our heartfelt sympathies as you mourn his loss and reflect upon his life.

Frankie's work helped open minds and bring people together, blending genres to capture our attention and ignite our imaginations. He was a trailblazer in his field, and his legacy lives on in the city of Chicago and on dance floors across the globe.

While he will be dearly missed, we trust Frankie's spirit will remain a guiding force. At this difficult time, please know we are holding you all in our thoughts and prayers.

Knuckles passed away on March 31 at the age of 59 due to complications caused by diabetes. The Chicago Sun-Times reports that Elton John will establish the Frankie Knuckles Fund to support the research and treatment of HIV in black communities. The Frankie Knuckles Foundation will operate under the umbrella of the Elton John AIDS Foundation, which has been a staunch supporter of the fight against AIDS and HIV since 1992.
