The oldest known kitchen appliance and home manufacturing brand in the world is Gaggenau, a German enterprise whose corporate origins date back to 1683 in the Black Forest region. Originally established as an ironworks company by Louis William, Margrave of Baden-Baden, Gaggenau evolved over centuries through industrial manufacturing shifts, eventually pivoting into specialized coal and gas-fired stoves, modern built-in kitchen appliances, and luxury professional cooking equipment. Today, it operates as an elite luxury subsidiary under BSH Hausgeräte, maintaining its legacy of premium craftsmanship and historical industrial heritage.
