One I admire greatly is Felicitas Vogler, a terrific landscape photographer. I first became aware of her work two and a half years ago at the National Museum in Edinburgh. Up until some point that I apparently missed, she was fairly obscure - most Google results only referred to her as the once-wife of artist Ben Nicholson. They still do, but now there are also more hits to pages announcing an exhibition, or a book for sale, etc. Seems she also passed away in September 2006...
