Reuben and Rose Mattus founded which ice cream brand in New York City?

Häagen-Dazs is an American ice cream brand, established by Reuben and Rose Mattus in The Bronx, New York, in 1960. Starting with only three flavors: vanilla, chocolate, and coffee, the company opened its first retail store in Brooklyn, New York, on November 15, 1976. The business now has franchises throughout the United States and many other countries around the world including Japan, the United Kingdom, Australia, India, South Africa, China, Lebanon, New Zealand, Peru, Mexico and Brazil.

Reuben and Rose met in Brownsville, Brooklyn, New York. After finishing high school, Rose went to work as a book-keeper at the Senator plant in 1934, and the two married in 1936. Reuben consulted some books and started to make a new heavy kind of ice cream. In 1959, he decided to form a new ice cream company with a foreign-sounding name. He invented the Danish-sounding 'Häagen-Dazs' as a tribute to Denmark's exemplary treatment of its Jews during the Second World War, adding an umlaut which does not exist in Danish, and even put a map of Denmark on the carton.
