Thermador invented the first wall oven and cooktop and introduced stainless steel to home appliances. By 1948, Thermador introduced the first “Pro Range” for residential use. Patterned after commercial restaurant equipment, Thermador developed the first home version warming drawer in 1952, a handy kitchen appliance that keeps dishes and foods warm while the oven is being used. Thermador continued to improve on kitchen appliances with the first self-cleaning oven in 1963.
