8 1920 marketed it very successfully as the “Fany Electroiler”. Already by the turn of the century many upper class households, bars, restaurants and factories were fitted with the marvellous cooling device. Later, the developed ceiling fans were fitted with four rather than two blades, which improved their smoothness and energy efficiency. In the “Golden Twenties” there was hardly a bar, a restaurant, a drugstore grocery store or a factory that did not use this new miracle of technology for cooling. With the Great Depression and its consequences for the population, ceiling fans went completely out of fashion. 1948: Marelli, Italy, cast iron and sheet steel, blade diameter 200 mm ca. 1940: Aeros, Germany, aluminium and sheet steel, blade diameter 300 mm 1945: Aeros, Germany, cast iron and sheet steel, blade diameter 250 mm Circa 1950: Fabbriche Elettrotecniche Riunite, Italy, Rubber and Steel, blade diameter 250 mm 1920: Extract from The Safety Car Heating and Light Company Based on the work of Thomas Edison and Nicola Tesla, who promoted the widespread supply of electricity, Dr. Schyler Skaats Wheeler published the first details that enabled using the then brand-new electrical energy to make fan blades rotate. This fan was built and marketed by the Crocker & Curtis Electric Motor Co. It had a two-bladed impeller, and yet did not have any kind of guard. The early days of electrical products were not easy for manufacturers. At this time AC and DC power were competing with each other. Voltages and frequencies were not standardised and often several systems were available in the same part of a town. In response, fans that could be operated with different electrical systems came onto the market. However, since they caused a lot of interference, they swiftly disappeared from the shops. In 1882 a German immigrant, Philip H. Diehl, who worked at the time for the Singer Sewing Machine company, constructed an electric sewing machine motor fitted with an impeller and installed it on the ceiling. He patented the first electric ceiling fan in 1887 and 1889. He and his competitor, Johnny Fany, both used Singer motors. Shortly after its development Fany enhanced his invention with a light and 1950
