In 1912 Alfred Eugene Ritter and his wife Clara founded a chocolate and confectionery factory in Bad Cannstatt in Stuttgart. In 1932 Clara created a chocolate bar that would slide easily into every man's jacket pocket and weighed the same as a normal longer bar. Since then, the square format has become recognised the world over as the unique shape of the chocolate from Baden-Württemberg. Today the firm's HQ in Waldenbuch houses a chocolate exhibition, 'chocoworkshop' and a collection of square-shaped artworks.
