Here's an author whose books I bet you own: Kaplan Inc. founder Stanley Kaplan died Sunday at the ripe old age of 90, having sold his homegrown test-prep company (begun after he failed to get into medical school) to the Washington Post. Even if you still have nightmares about #2 pencils, his story is fascinating; he figures prominently in Jerome Karabel's THE CHOSEN, a great book about American higher education, prejudice and the redefinition of "character" in a meritocracy.
