At least two people were not pleased with John Jeremiah Sullivan’s recent cover story in the New York Times Magazine. In a letter to the New York Observer (and an expanded post on Google+), Susannah McCormick – daughter of renowned music historian Robert “Mack” McCormick – alleges that Sullivan and his research assistant “glibly” stole her father’s research in an act of “quasi theft.” In his response, Sullivan asserts that, “by hiding L. V. Thomas’s voice, by refusing for over half a century to credit or even so much as name the two singers who created those recordings while they or their contemporaries were alive, Mack McCormick committed a theft—through negligence or writer’s block or whatever reasons of his own—far graver than my citation of interviews L.V. granted him decades ago.”
