Dr. Kligman, the dermatologist and educator who led Retin-A to market, among other achievements, passed away on February 9, 2010, at the age of 93. He was a signature example of the commitment and sense of inquiry and innovation that’s led to so many breakthroughs over the years in both the sciences, and their practical application in the realm of personal care products. His endowments to the University of Pennsylvania, and the influence he’s had on generations of students, will ensure the progress and good works he initiated will continue well into the future.
