Invention of the immersion blender
In 1950, Perrinjaquet applied for a patent for a "portable kitchen appliance". The new mixer was named Bamix, an abbreviation of the French "battre et mixer" (to beat and mix). In 1954, Perrinjaquet sold his patents to ESGE KG, a company founded a year earlier by Messrs. Spingler and Gschwend. From the end of 1954, this company produced the first hand blenders in its factory in Germany. According to ESGE AG, Perrinjaquet described the world's first portable hand blender with his 1950 patent.[1]
