Marva Collins (August 31, 1936 - June 24, 2015) was an American educator who in 1975 started Westside Preparatory School in Garfield Park, an impoverished neighborhood of Chicago, Illinois. She ran the school for more than 30 years until it closed in 2008 due to lack of sufficient enrollment and funding. She is famous for applying classical education successfully with impoverished students, many of whom had been wrongly labeled as learning disabled by public schools. She once wrote, "I have discovered few learning disabled students in my three decades of teaching. I have, however, discovered many, many victims of teaching inabilities."
Here is her obituary in the New York Times, June 28, 2015.
