J.K. Rowling's charity founded in 2005 to support vulnerable children and families is Lumos.
The organization was originally called the Children's High Level Group. Rowling became its president after helping draw attention to children living in institutions in Eastern Europe. The charity was renamed Lumos in 2010, taking its name from the light-producing spell in the Harry Potter books.
Lumos campaigns to end the institutionalization of children and to replace large residential institutions with family-based or community-based care. Its work includes research, advocacy, and support for reforms intended to keep children safely with families whenever possible. The organization operates internationally and has worked with governments and local partners.
The charity's name is a literary reference, but its mission is practical rather than fictional. Rowling has used her public profile to raise awareness of the effects that institutional care can have on children's development and family relationships.
