The first in a series of memorial services honoring Floyd will take place Thursday afternoon.
His family, friends and a number of guests will gather at the North Central University in Minneapolis. Rev. Al Sharpton, the founder of the National Action Network, will deliver a eulogy to honor Floyd's life.
"We must turn this moment into a movement," Sharpton told reporters on Wednesday, describing Floyd as a "linchpin" for police accountability.
Minnesota Gov. Tim Walz said Thursday's memorial would be a chance for everyone to heal.
"It's critically important for them to see and for Minnesotans to display to them that there's another side to us and to this state that they didn't see last Monday night," Walz said on Wednesday.
Anyone who met Floyd couldn't miss seeing him. He was 6 feet 4 inches tall, a "gentle giant."
"Knowing my brother is to love my brother," Philonise Floyd, George's brother, told CNN's Don Lemon.
"He's a gentle giant, he don't hurt anybody."
