Roald Dahl's Marvellous Children's Charity is a charitable organization based in the United Kingdom. The charity was founded in 1991 as the Roald Dahl Foundation by Felicity Dahl, in memory of her husband, children's author Roald Dahl. The charity provides specialist support for seriously ill children across the UK by sponsoring 'Roald Dahl Nurse Specialists' roles who work within NHS Trusts to provide practical and emotional support to children with complex, often life-long, medical conditions. The charity also provides support services for the families of children with complex medical needs, and financial grants.
