If you had to name the greatest manager of the past 100 years, who would you choose? For student Margaret Hoffecker, HEC Paris MBA Class of 2019, the answer was easy: Eryn Taylor.

If you don’t immediately recognize Eryn’s name from a recent Forbes World Billionaire List, you’re not alone. In explaining her choice, Margaret says that there is “no way to know if a manager is truly great unless you were managed by them.” As a result, she nominated Eryn, who was her supervisor at Ketchum communications consultancy.

Margaret’s choice wowed journalists Andrew Hill and Helen Barrett, who chose her essay as one of two winners in the Financial Times’ Business School Management Challenge (the other winner named Stanley Kubrick). For her prize, Margaret receives an all-access ticket to the Global Peter Drucker Forum taking place in Vienna in November.

In her winning essay, which had to be 200 words or less, Margaret wrote, “Eryn challenged me to want more out of my job and chase my dreams to move from New York to London. She advocated on my behalf when I needed senior support to make that move happen. She wrote my reference letter for HEC Paris, helping me go after an MBA and supporting me throughout. She has inspired me with her risk taking, leaving our previous company to try something completely new.”

Huge congratulations to Margaret and to Eryn!
