The first attempts to produce molded whistles from a material known as volcanite, in 1906, were unsuccessful. But in 1914 as bake-a-lite started to develop as a molding material, the first early plastic whistles were made. These opened up new vistas for whistle makers with colors and designs that had not previously been thought of. Art-deco, the age of jazz, saw the Hudson's catalog swell to over 300 different models, many of them plastic and now highly collectable. In 1949, the world's first life-saving whistle, for use on life-jackets and flotation devices, was developed and patented. Another new area for whistle makers to explore.
