Management and psychology professor Adam Grant has been the highest-rated teacher at the Wharton School of the University of Pennsylvania for the past four years, and the youngest to achieve tenure. In 2009, a student asked Grant to invest in a business he was starting with classmates, an online eyewear retailer they named Warby Parker. Grant declined, thinking the idea was doomed, but when the students proved him wrong, he set out to discover why. His 2016 book, Originals: How Non-Conformists Move the World, shares the science behind why some ideas succeed while others fail. Grant personally embodies his research; he was a junior Olympic springboard diver and professional magician. He’s been recognized in the Thinkers50 rankings of the world’s most influential management thinkers, and as one of the world’s best business professors under 40.
