Erwin Franz Mueller
- Erwin Franz Mueller owns an eponymous drugstore chain with over 750 stores across seven European countries.
- The business dates to 1953, when Mueller opened a hairdressing shop in his home in Ulm, Germany.
- It has maintained steady top-line growth despite a series of executive departures, reportedly in part due to disagreements with Mueller.
- In 2016, German authorities stopped court proceedings against Mueller involving him having concealed assets in Swiss private bank J. Safra Sarasin.
- Mueller sued the bank, and in 2017 a German court ruled that the bank had to pay him $50 million in compensation for incorrect investment advice.
