Goldman Sachs Group donated $2 million to endow a chair at Morehouse College in Atlanta that will oversee the collected writings of the Rev. Dr. Martin Luther King Jr. The chair will supervise the compilation of 10,000 pieces of Dr. King’s writings and manuscripts, Goldman Sachs said. Dr. King was a 1948 graduate of the all-male, historically black college. A group of civic leaders, businesses and philanthropists based in Atlanta bought the collection, which includes a draft of Dr. King’s 1963 “I Have a Dream” speech, last year after it was to be auctioned by Sotheby’s for more than $30 million
