Marguerite Patten, the home economist and chef who helped educate Britons on how to survive on rations during World War II, has died. She was 99.

Her family said Wednesday that Patten died on June 4. She suffered a stroke in 2011, and had been living in a nursing home.

Patten, who was born in Bath, was a senior adviser during the wartime-era Ministry of Food and sought to show how families could stay healthy on rations.

At a time when Britons were encouraged by campaigns such as "Dig for Victory," and were turning soccer fields into vegetable patches, Patten offered advice on how to avoid waste.

She appeared on the BBC and wrote some 170 cookbooks, with sales of 17 million. She traveled around Britain for decades giving demonstrations.
