In 1977, Barbara Riverwoman, Mary Ann McGivern and several other women decided to respond to the military - industrial complex as personified by the McDonnell Douglas corporation. Shareholder resolutions were drafted and conversations started with the machinists.

At the end of the decade, a proposal was submitted to the Ford Foundation, which subsequently provided a $29,000 grant with the understanding that staff would be hired and analysis made of the impact of military spending in St. Louis. Mary Ann and Susan Jordan joined the staff, and Bill Ramsey was recruited from North Carolina.

1980s

In the early 1980s, SLECP moved into its Skinker office, and Chuck Grunther was hired to run the staff. As an engineer who had worked for McDonnell Douglas, he had an appropriate perspective for the size and culture of military spending in the country. With the election of Ronald Regan, a new special challenge developed - how to help the nation understand the folly of the "star wars" initiative, as well as appreciate the complexity and waste associated with military contracts during a time of explosive defense spending.

In the second half of the decade, Chuck left to pursue teaching and Mary Ann and Virginia Nebitt joined the staff. They continued to analyse the economic dependance on the military economy being experienced by the St. Louis region. Emerson Electric, General Dynamics, McDonnell Douglas and more than 700 other prime defense contractors collectively accounted for around 74,000 people (6.4 percent of the workforce) and 2.3 billion (8.4 percent of the wages).

1990s

In July 1990, McDonald Douglas announced plans to eliminate 4500 jobs in St. Louis. Then in 1991, with the cancellation of the A-12 project, another 5000 people were terminated. The cold war was clearly over. The St. Louis Economic Conversion Project joined a regional advisory committee to oversee a government supported Economic Adjustment and Diversification Program.

An economic adjustment plan was prepared, surveys of workers and defense contractors conducted, and a variety of special projects begun. SLECP helped prepare several federal grants, and devoted special attention to a St. Louis Technology Transfer and Management Assistance Program, and a Business Assistance Network. Lance McCarthy joined the staff with a focus on finding investors for distressed sites in the inner suburbs.

In the mid nineties, SLECP entered into a contract with the St.Louis Development Corporation in order to help small manufacturers within the City to improve communication and collaboration amongst themselves. This followed an active effort by SLECP to define projects that could be built into the 1994 St. Louis Empowerment Zone application. The $10,000 award from the City’s Enterprise Community program resulted in formation and initial support for the St. Louis Manufacturing Association.

After a slower time period in the late nineties, Chris Stolz and Marie Andrews were hired. With their assistance, concern returned to the issue of missiles in space, a high priority project in the mind of the new Bush Administration. Drug interdiction efforts in Latin America were also examined.

Marie left in 2001, and Chris left in the summer of 2002, moving with his wife to a new service opportunity in Burundi. Chrissy Kirchoefer left the Board to provide part time staff support in the summer. She was joined in the fall of 2002 by Catherine Marquis-Homeyer. Chrissy Kirchoefer left the staff to pursue other interests in summer 2004.

The name of the organization was changed to the Peace Economy Project in October 2002. The new focus of research became the St. Louis area-based military division of Boeing Company, the area's second largest employer and the nation's number two military contractor.
