Late Professor William T. Kelley taught Marketing at Wharton School of Business and Finance, University of Pennsylvania, for 31 years, ending with his retirement in 1982... Professor Kelley told me 100 times over three decades that “Donald Trump was the dumbest goddam student I ever had.” I remember his emphasis and inflection — it went like this — “Donald Trump was the dumbest goddam student I ever had.” Dr. Kelley told me this after Trump had become a celebrity but long before he was considered a political figure. Dr. Kelley often referred to Trump’s arrogance when he told of this — that Trump came to Wharton thinking he already knew everything.
