Elizabeth David Ltd was never more than modestly profitable, but David would not lower her standards in search of a commercial return. A new manager was brought in to run the shop and David fought against many of his changes, but she was always in the minority against her fellow directors. The stress of disagreements over company policy—and the deaths of her sister Diana in March 1971 and her mother in June 1973—contributed to health problems and she suffered from chronic fatigue and swollen, ulcerous legs. Gradually her business partners found her commercial approach unsustainable, and in 1973 she left the company. To her annoyance, the shop continued to trade under her name, although she tried periodically to persuade her former colleagues to change it.
