 The American Academy of Dermatology recognized Ackerman in 2004 with its Master Dermatologist Award which recognizes "an Academy member who throughout the span of his or her career has made significant contributions to the specialty of dermatology" and to the leadership and education programs of the Academy.He wrote some 700 papers and 60 books and provided expert testimony at 200 trials.One of his final papers, published in the "Archives of Dermatology" in 2008, was titled "An Inquiry Into the Nature of the Pigmented Lesion Above Franklin Delano Roosevelt's Left Eyebrow", in which Ackerman argued that the failure of Roosevelt's physicians to consider the possibility of melanoma shows the flaws in medical wisdom at the time for diagnosing such lesions.
