It is known that Edison and Swan almost simultaneously invented their incandescent lamps, but at least 22 inventors had already created similar light products. However, Edison’s and Swan’s lamps stand out, because they were perfect for mass production, and therefore more commercially viable. Despite a couple of law suits, Edison and Swan joined forces and created the 'Edison and Swan Electric Light Company' in 1883. The first lights were of course very functional and rudimentary, even dangerous, and the design was pretty basic. But it wasn’t long before people started experimenting with creative designs to give lamps more appeal instead of a bulb hanging on a thread.
One of the first eras in which people experimented with lamp design, was the Art Nouveau/Jugendstil period. This style was most popular between 1890 and 1910, so basically the same period as electric lights became more and more popular. One of the pioneers in lamp design from this period for example was Émile Gallé, who made sculpted glass lamps. Later periods are: Art Deco (1920s), Modernism (1950s and 1960s).
