Mary Weidner is a figurative artist, whose recent work has focused on two themes; the Family and the Body. The complex dynamics of the family, as civilization's most fundamental social unit, are explored in many pieces. Paintings, drawings and mixed-media installations examine the shared histories, intimacies and layers of emotion, which form our understanding of this uniquely personal and yet inherently universal experience. Her works concerning the body, are often self-portraits, and examine the areas of health, illness, sexuality, aging, and the female.

Weidner's work has been shown at the Katharina Rich-Perlow, George Billis, Henry Street Settlement and A.I.R. galleries in New York; at The Art Center, the Esther Saks and the Deson-Saunders galleries in Chicago; at the Koslow Rayl Gallery in Los Angeles; and in other cities throughout the U.S. including: Washington, St. Louis, Indianapolis, New Orleans, Las Vegas, Portland, and San Diego. Internationally, Weidner has received travel grants to study in Spain, Germany, Italy, Mexico and Central America, and has participated in exhibitions and residencies at the Ferencvarosi Pince Gallery in Budapest, Hungary; the Museo Hosio in Italy; the Poznan Academy of Fine Arts in Poland; and at the Nagoya-Zokei College of Art and Design and Aichi Prefectural Museum in Japan. She has lectured widely, most recently at "Mothers and the Economy: The Economics of Mothering Conference" at Ryerson University in Toronto. Both the Pennsylvania Council on the Arts and the Heinz Foundation have awarded her grants.

Professor Weidner teaches drawing and painting courses at all levels, holds the College of Fine Arts Henry Hornbostel Award for Teaching, and has served as Chair of the Drawing, Painting, Printmedia and Photography Area in the School of Art at Carnegie Mellon several times. Washington University in St. Louis granted Ms. Weidner her BFA and MFA degrees and a Milliken Traveling Fellowship to Mexico.
