Geronimus Hatt, who obtained his Master Brewer's certificate in 1649, started up the Canon Brewery in the Place du Corbeau in Strasbourg. His son Claude (born November 1665), succeeded his father in the trade in 1683. However, the frequent flooding of the River Ill compelled in 1850 a move to the higher terrain of Cronenbourg, an area of Strasbourg. In 1922, the Hatt Brewery changed its name to Tigre Bock, the most well-known brand of the Tiger Brewery it had acquired to become the leading brewer in Alsace. Following the Second World War, Kronenbourg became the name of the company, and began international expansion. In 1970, it was acquired by industrial group BSN (now Groupe Danone), along with the Société Européenne de Brasseries (Kanterbräu). In 1986, Kronenbourg merged with Kanterbräu. In 1952, the 1664 is commercialised in honour of the coronation of Her Royal Majesty Queen Elizabeth II.
