Sheila Daar. Courtesy family Sheila Daar, June 25, 1943 – Sept. 5, 2020 Sheila Daar died early Sept. 5 after a long battle with dementia. It is very hard to describe in a few words Sheila Daar, as she was a real force of nature. The first words that come to mind: she was a real “Renaissance woman.” She had five extremely successful careers, was a very active retiree and an activist her entire life. Sheila was an “Air Force brat” and grew up in several places, including a few years in England.
