Wilton artist David Dunlop will present a talk on renowned artist Georgia O'Keeffe Wednesday, Oct. 17, 11 a.m., at the Lockwood-Mathews Mansion Museum, as part of the museum's lecture series, "Defying Expectations: Independent American Women of the Early 1900s."

In his talk, "The Roots of American Women Modernists," Mr. Dunlop will explore O'Keeffe's world and her adventure in painting, education, and community; "a microcosm of a modernist woman's triumph of personal imagination over a sexist culture," a museum press release said. Mr. Dunlop's lecture will also look at how the elevation of artists to star status worked against women, effectively excluding women from a role which had been more accessible to them when artists were seen as skilled artisans and not celebrities.

During a period when women fought for the right to vote, O'Keeffe was a "pioneer in a culture of oppressiveness toward women who had ambition and insight," the press release said. She "contributed innovatively to the evolution of modern art at its start."

Mr. Dunlop is an internationally known landscape painter as well as art historian, lecturer, teacher and national television host. He has been a lecturer at the Metropolitan Museum of Art and a host of a 13-part PBS television series, "Landscapes Through Time with David Dunlop."

His work is represented in more than 50 corporate collections as well as the U.S. State Department.

Admission to the lecture is $30 for non-members, $25 for members and includes a light lunch courtesy of Michael Gilmartin of Outdoor Cookers, and a tour of the first floor of the mansion at 295 West Avenue in Norwalk.
