The Khan Academy received a grant of $2.2 million from the Leona and Harry Helmsley Trust to create math lessons aligned to the Common Core.

Harry Helmsley was a real estate baron in New York City. When he died, his wife Leona inherited his huge estate. She was convicted of tax evasion and went to prison. She once memorably said, “only the little people pay taxes.” She was known as “the queen of mean.” Her only son died of a heart condition, and Leona sued her daughter-in-law and evicted her from her home. She left an estate worth billions and set aside $12 million for her dog Trouble. A court reduced the amount to $2 million, as adequate to the dog’s needs.
