Group Danone (French?) owns Dannon yogurt now but it was founded by Sephardic Jews. Ironically it's now on the Frog boycott list
Everything changes when Isaac Carasso then his son Daniel set up, in Spain, then in France, Danone. Stemming from a Sephardic family of Salonique, Isaac Carasso settles down in Barcelona during the first world war.
In 1919, he begins the manufacture of yoghourts in a small workshop of the Catalan town, the street Los Angeles, right by the famous Ramblas. Regular visitor to Metchnikoff's works, Isaac Carasso believes in the virtues of lactic ferments to fight against the intestinal, frequent infections then to the small Catalan.

The Dannon Company, Inc. has its roots in Spain, where Danone was founded by Isaac Carasso in 1919. Having previously lived in the Balkans where yogurt was a dietary staple, Carasso decided to introduce this healthy product in Barcelona by opening a small yogurt business named "Danone," meaning "Little Daniel" after his son. Isaac Carasso was aware of scientific advances that had been made with fermented milk products by Elie Metchnikoff at the Pasteur Institute in Paris. He had the idea to combine the traditional method of making yogurt with the pure cultures that had been isolated in Paris, thus perfecting the first industrial manufacturing process for yogurt. The younger Carasso, Daniel, learned the family business in Spain and decided to establish Danone in France in 1929.
