In May 1963, Hardge moved to Providence, Rhode Island, to become the pastor of the Hood Memorial A.M.E. Zion Church. He co-founded and chaired the state chapter of the Congress of Racial Equality and served as executive secretary of the Rhode Island Commission Against Discrimination from 1965 to 1968. He helped to organize sit-ins, legal actions, and legislative pushes to advance fair housing, anti-poverty measures, and school desegregation in Rhode Island. He was instrumental to the passage of the Rhode Island Fair Housing Law.[1][2] In 1967, Hardge co-founded and chaired the state branch of the Opportunities Industrialization Center (OIC), whose mission is to provide job training and adult education to underprivileged community members. Under Hardge's leadership, the Rhode Island OIC moved into a new 80,000-square-foot facility in South Providence, built at a cost of $6 million.[2]
On July 25, 1968, Hardge became Rhode Island's first African American cabinet member and the first African American to lead a state agency when Governor John Chafee, a liberal Republican like Hardge, appointed him to serve as the first director of the Rhode Island Department of Community Affairs. Governor Frank Licht, a Democrat, unseated Chafee in the 1968 election and did not reappoint Hardge to the cabinet in January 1969.[1]
On June 5, 1969, Hardge became assistant director of the Program for Disadvantaged Youth, based at the University of Rhode Island. The program was intended to promote the pipeline of underprivileged young people, especially racial and ethnic minorities, from high school to college. It facilitated student success while combating racial discrimination on campus. Hardge was promoted to program director in September 1969 and rebranded the program to Special Program for Talent Development (TD). The program grew from only thirteen students to approximately 600 students admitted each year.[1][4]
Hardge was the University of Rhode Island's first African American administrator. He also served as a special assistant to the president.[2] On September 12, 2000, URI dedicated a memorial statue of Hardge. The black marble statue is located outside the Multicultural Center on URI's Kingston campus.[2]
Hardge died from heart disease in 1983 at the age of 56. His son, Marc Hardge (born 1964), was a talent development coordinator at URI as of 2016.[5]
