The Family of Hemel Hempsteads Doris Taylor MBE still receive royalties for her initiative in 1943.
Doris invented the concept of hot meals delivered to the home with her Meals On Wheel concept, which is now taken up by Just Eat and others, who are each obliged to pay royalties.
I'm not totally sure if the original claims still hold true, where research shows that home-delivered meal programs significantly improve diet quality, increase nutrient intakes, reduce food insecurity and improve quality-of-life among the recipients. The programs also reduce government expenditures by reducing the need of recipients to use hospitals, nursing homes or other expensive community-based services.
