Billionaire Ron Lauder has hired American Continental Group to aid his mission in recovering Nazi era-confiscated art from museums and returning the works to the heirs of their owners.

The scion of the Lauder cosmetics fortune is an avid art collector who is active in Jewish affairs and is president of the World Jewish Congress, reports O'Dwyer's.

Museums in Germany, Switzerland, UK and the US are among Lauder's chief targets for restitution cases, he told the New York Observer.
