from Wikipedia: http://en.wikipedia.org/wiki/Callebaut

Callebaut was a Belgian company and a major producer of chocolate for consumers and for professional chocolatiers. As of 1996 it is a part of the Swiss company Barry Callebaut. Callebaut is now one of the major brands of the combined company. The company was founded by Eugenius Callebaut as a brewery in Wieze, Belgium, in 1850, and began producing chocolate bars in 1911 and chocolate couverture in 1925. [1]In 1996, Callebaut merged with rival chocolatier Cacao Barry to form a new company, formally known as Barry Callebaut, with headquarters in Zurich, Switzerland, although Callebaut retained its offices in Belgium. In 2005 Barry Callebaut was noted as "the world's biggest chocolatier."[2]

A separate company in Canada, Bernard Callebaut, was started by a Belgian of the same name. He lost ownership and operates as Papa Chocolat out of Calgary, Alberta. http://papachocolat.ca/ I studied chocolate making with him for one day as we were considering to buy a franchise. It is the best chocolate we have ever had anywhere. The new owners of the oricginal still use his formulas and it remains excellent chocolate. There is one store in Lake Oswego, Oregon. They will ship anywhere in USA.
