A memorial service was held at a monument to the victims at Queen of Heaven Cemetery in Hillside.
There were 92 children and three nuns who were killed in the fire in Chicago's Humboldt Park neighborhood.
Victims included three members of the "Chicago Royal Airs" Drum and Bugle Corps.
A Corps member who survived shared his memory of one who died in his eulogy.
The "Chicago Royal Airs" have been part of every memorial to the fire since reuniting in 2001.
