This week's famous immigrant is award-winning chef, Wolfgang Puck.  From his website:

Puck began cooking at his mother's side as a child. She was a chef in the Austrian town where he was born, and with her encouragement, Wolfgang began his formal training at fourteen years of age. As a young chef he worked in some of France's greatest restaurants, including Maxim's in Paris, the Hotel de Paris in Monaco, and the Michelin 3-starred L'Oustau de Baumanière in Provence. At the age of 24, Wolfgang took the advice of a friend and left Europe for the United States.

From TV shows to product lines to his empire of restaurants and catering companies, Wolfgang Puck embodies the American immigrant's entrepreneurial spirit!  You can read his biography here.
