Ridgefield residents Benjamin Ortiz and Victor Torchia Jr. are donating a portion of their substantial contemporary art collection to the Mattatuck Museum in Waterbury.

The donation coincides with the exit of Marie Galbraith, who is stepping down as director of the museum and moving to Director of Education and Public Programming. The donation represents the work of 31 artists, the number of years Galbraith served at the Mattatuck.

The donation contains a variety of art forms including painting, photography, watercolors, etchings and mixed media. It represents such movements as figurative realism, feminist art, social commentary, color and abstract art. It includes:

• a 1955 black-and-white photograph, Grand Central Station, by Larry Silver
• Antonio Frasconi’s colorful woodcut Sioux Chief, 1971
• a mixed media work, Esperanza, 1995, by Yolanda Vasquez Petrocelli (pictured)
