Le Blanc studied at the University of Pittsburgh, focusing on history and receiving a Bachelor of Arts degree in 1971, a Master of Arts degree in 1980, and a Doctor of Philosophy degree in 1989.[1]
In 1965, Le Blanc joined the “New Left” group Students for a Democratic Society (SDS).[4] In 1966, as a conscientious objector, he worked for the Quaker-based American Friends Service Committee in Pittsburgh and Baltimore. In the early 1970s, he served on the board of the Pittsburgh Peace and Freedom Center and the coordinating committee of the National Peace Action Coalition (1971-1974). He opposed the Vietnam War and supported anti-racist activity – most prominently as part of the Pittsburgh Black Construction Coalition of 1969 – pro-feminist activities, defense of Latin American political prisoners, and Central America solidarity work.[5]
Since 2000, Le Blanc has supported the Green Party. He has opposed war and militarism, including US military intervention in Iraq and Afghanistan. He also collaborated closely with South African poet and global justice activist Dennis Brutus in building Pittsburgh participation in World Social Forums taking place in Porto Alegre, Brazil, in 2003 and Mumbai, India, in 2004.[9]
In 2000, Le Blanc joined the faculty of La Roche College (renamed La Roche University in March 2019)[1] as Dean of the School of Arts and Sciences (2003-2009) and as a professor of history.[10]
