Isaac Carasso (1874 – April 19, 1939) was a member of the prominent Sephardic Jewish Carasso family of Ottoman Selanik (modern Thessaloniki, Greece). After emigrating to Barcelona, he started a yogurt factory which later became Groupe Danone.
He noticed that many young children suffered from digestive and intestinal problems. Inspired by the work of Ilya Ilyich Mechnikov, who had popularized sour milk as a health food, and recalling that such health conditions were treated with yogurt in the Balkans, he imported cultures from Bulgaria or used "pure cultures that had been isolated in Paris" at Mechnikov's laboratory at the Institut Pasteur. Since yogurt was not well known then in Western Europe, he initially sold it as a medicine, through pharmacies.
He founded the company which would later become Groupe Danone in Barcelona in 1919 when he opened a small yogurt business named "Danone", a variation on the Catalan nickname of his son, Daniel. Carasso perfected the first industrial process for making yogurt.
Isaac Carasso died in France in 1939.
