In Memoriam

Gwendolyn Lewis, a former sociology professor with important positions in the National Research Council, National Science Foundation, and U.S. Department of Agriculture, was a professional photographer who volunteered her time as our photographer since our founding in 1999 until she died from cancer in 2012.

As our photographer and friend, Gwen is responsible for the many memorable color photographs of the exceptional women who received our Foremother awards, as well as capturing many other important people and moments through the years.  As an artist, however, she specialized in black-and-white photography, with an emphasis on architectural subjects. Her work was exhibited in more than 100 shows in the Washington area and won many awards.
