Fifty years ago, Rachel Carson published “Silent Spring,” a lucid and compelling book about how DDT and other pesticides were damaging the environment and human health. The book called for a change in the way humankind viewed the natural world and became an inspiration for the environmental movement. One of Carson’s staunchest advocates and closest friends was Iowan Shirley Briggs, who met Carson when they worked together at the U.S. Fish and Wildlife Service in the 1940s.

To recognize this Iowa connection to “Silent Spring,” the University of Iowa Libraries and Office of Sustainability presented an exhibition, Thursday, Nov. 15 - Sunday, Jan. 7, at the University of Iowa Sciences Library, inspired by the extensive collection of Briggs’ diaries, letters, photos and artwork in the Iowa Women’s Archives.

Briggs, an Iowa City native, was the author of “Basic Guide to Pesticides” (1992), inspired by the many requests for information about pesticides after “Silent Spring” was published in 1962. Briggs attended the University of Iowa earning a B.A. in art, art history, and botany in 1939 and an M.A. in art and art history in 1940. She studied with Grant Wood at UI. In 1945, she was hired by the U.S. Fish and Wildlife Service as an artist. She became close, lifelong friends with Carson and with other noted naturalists, such as Roger Tory Peterson, through her work as editor of the Atlantic Naturalist, a publication of the Audubon Naturalist Society of the District of Columbia.

After years of research in the United States and Europe, Carson made the decision to produce “Silent Spring.” This landmark work was linked to the increase of awareness of the impact of persistent, bio-accumulative chemical pollutants in the environment – these include DDT, mercury, Chlordane and Dieldrin, among others. These deadly chemicals are still being cleaned up and removed from the environment.

After her book’s publication, Carson was vilified by chemical companies. Her writings about the impact of legacy chemicals led to landmark legislation and the banning of the use of DDT. She died in 1964 after a long battle against breast cancer. After Carson’s death, Briggs created a non-profit organization, the Rachel Carson Council, a pesticide research information clearinghouse for both scientists and lay people.

Just eight years after “Silent Spring” was published, President Richard Nixon established the Environmental Protection Agency and with an extensive directive, helped pave the way for a series of important environmental laws, such as the Clean Air and Clean Water Acts.
