DJ Frankie Knuckles passed away on March 31 due to complications with diabetes. President Obama and First Lady Michelle Obama penned a letter to his loved ones.

It reads:

"We are 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 in all of your thoughts and prayers."

The letter was posted on Knuckles' good friend and business partner David Morales' Facebook page following Monday night's memorial service. He captioned it, "You know you're a TRUE LEGEND when you get one of these."

This is not the first time President Obama paid tribute to the "godfather of house." When he was a senator, he pronounced Aug. 25, 2004 as "DJ Knuckles Day," according to Rolling Stone. He also renamed part of Chicago's Jefferson Street to Frankie Knuckles Way.

Mayor Rahm Emanuel also released a statement following his death, stating:

"While the stretch of Jefferson Street between Monroe and Van Buren is officially known as 'Frankie Knuckles Way,' all those who are part of the house music genre, no matter where they are from, walk along the path Frankie created."

Knuckles was born in New York and moved to Chicago in the late 1970s, when house music was still in infancy. He brought a new sound to dance music in the underground Warehouse nightclub.

The late DJ obtained a Grammy award in 1997, and in 2005 he was inducted into the Dance Music Hall of Fame. He has worked with some of the most well-known musicians including Diana Ross and Michael Jackson.

How nice of the First Family to pay tribute to a staple in the music industry! Do you agree? Sound off below!
