J.K. Rowling’s charity supporting children separated from family care is Lumos.
Rowling founded Lumos in 2005, originally under the name Children’s High Level Group. The organization works internationally to end the institutionalization of children and promote family-based care, including family reunification, foster care, and adoption where appropriate.
The charity was inspired in part by reporting about children living in institutions, including photographs from Eastern Europe. Its name changed to Lumos in 2010. The word refers to light and also recalls the light-producing spell in the Harry Potter universe, although Lumos’s work is a real-world child-welfare program rather than a Harry Potter project.
Lumos is sometimes confused with Rowling’s personal charitable foundation or with fictional wizarding organizations. Its specific focus is reforming systems that place children in institutions and helping children grow up in families or family-like settings.
