Professor William T. Kelley, who taught marketing at Wharton for 31 years and had Donald Trump in his classroom, said, “Donald Trump was the dumbest goddamn student I ever had,” in a conversation with his close friend Frank DiPrima.

The professor made the comment while president Trump was already a public figure, but had not yet ventured into politics.

Kelley “often referred to Trump’s arrogance when he told of this—that Trump came to Wharton thinking he already knew everything.”

DiPrima says; “Bill Kelley was one smart cookie.  His text book cited above [Marketing Intelligence — The Management of Marketing Information (originally published by P. Staples, London, 1968)] — published in the late 1960s — was standard in his time in the then-new field of ‘marketing intelligence’ and the necessity of using computers and data bases to manage it.”

It seems that Donald Trump hasn’t changed much in the last 50 years.
