Harmon Biddle is a local artist.  Her medium is watercolor on paper.  Her paintings are expressionistic, as she paints from recorded, and held, visual memories and impressions.  As a practicing psychoanalyst, her unconscious process is her instrument, as she lets a combination of colors and forms float back into her conscious mind.  The spiritual land of the southwest has been an inspiration for many of her works.

She has been exhibiting since 1997, showing both her original paintings and limited edition archival prints.  She is a member of Roving Artists, a non-profit arts organization consisting of 30 Washington DC Metropolitan area artists creating art in a variety of media and styles.  She is a member/painter at The Ralls Collection Gallery.

In the Spring of 2007, she began to participate in a project conceived by Adriano Berengo, Berengo Fine Arts in Murano, Venice, Italy.  The project, including a number of international artists, is to transform two dimensional works into three dimensional Murano glass sculptures. She works in the Berengo studio, in Murano, with the Master Glass Maker and his staff.  Their interest in her painting began with BLUE EGG.  They, and she, were able to envision a three dimensional transformation of this painting.  BLUE EGG, NIGHT, REMEMBRANCE, and several other paintings, featuring a variety of forms of eggs,  have been transformed into Murano glass sculptures.  She continues this work but her paintings remain her deepest and continuous expression.
