On This Day - July 8th 1904
Sydney's electricity supply is officially switched on.
The development of electric lighting is regarded as a major milestone in history. Inventors began experimenting with electric lighting from the early 1800s, but it was not until the 1870s that English physicist Sir Joseph Swan produced the first electric light bulb. Thomas Alva Edison then perfected the design and demonstrated the first durable and commercially practical incandescent lamp in 1879. Electric lightbulbs were far more practical, efficient and useful than previous forms of lighting, including outdoor arc lamps which produced intense heat as well as fumes, and for that reason could not be used indoors.
