Early life
O'Neill was born in London to Paul Cesario O'Neill (1926–2004), an American investment banker who came to London in the 1960s to set up the European head office of Oppenheimer & Co. His mother is Eva Maria O'Neill (née Walter). O'Neill has two half-sisters on his mother's side: Tatjana d'Abo and Countess Natascha von Abensberg und Traun, and three on his father's side: Stefanie, Annalisa and Karen. He grew up in London, St. Gallen, Austria and Germany, and holds dual American and British citizenship.
Education and career
O'Neill was educated at Eaton House and Westminster Under School in London, Institut auf dem Rosenberg in St. Gallen, Switzerland, and graduated with a BA degree in International Relations from Boston University. He also obtained an MBA from Columbia Business School in New York City. He was a partner and head of research at Noster Capital and former employee of NM Rothschild and Sons and Steinberg Asset Management. His marriage to a Swedish princess necessitated that, if he continued with Noster Capital, the fund would have to divest entirely from companies that traded on the Stockholm Stock Exchange and, moreover, divest from any company which had more than a third of its sales in Sweden. O'Neill resigned from Noster Capital in consequence of these demands.
