soldiers were being shipped to the South Pacific to engage in the conflict with Japan. George Maison, the president of Riker Labs (now 3M Pharmaceuticals), created the first-of-its-kind “metered-dose inhaler” at the suggestion of his asthmatic teenage daughter, who got the idea from perfume spray devices.Īs with many other inventions of the era - like the dynamo-powered torch (aka squeeze flash-light) and the jerrycan fuel container made from pressed steel - World War II was a major factor in how innovation informed usage. The device was further perfected with the introduction of a pressurized system. Abbot Laboratories developed the Aerohaler for inhaled penicillin G powder and launched the devicein 1948 with what could only be considered a Rube Goldberg- esque device in which air intake caused a metal ball to strike a cartridge. The medical profession was one of the biggest early adopters. By 1931, Rotheim was recognized for his invention in a legal context and viewed as a pioneer in the transfer of carbonated liquids into cups.

In 1926, Norwegian engineer Erik Rotheim applied for the first patent for an aerosol can that could hold products and dispense them with the use of propellants. Although it was an advancement in efficiency and cleanliness, it was a far cry from how aerosol would be used in a graffiti context. The concept of aerosol dates back to the late 18th century, when pressurized carbonated bever-ages were introduced in France. Prior to the October 2014 study in Indonesia, the animalistic imagery in Chauvet Cave in southeastern France, believed to be around 30,000 to 32,000 years old, was commonly thought to be the oldest example of art as we understand it today. And in one form or another, it is inherent in almost everything we do,” archaeologist Adam Brumm told Reuters.

“Archaeologists love to say things like ‘ability X is what makes us human,’ but in the case of the origins of art they are probably right. “Its emergence, therefore, marks one of the key moments when our species became truly human,” the BBC remarked following the announcement. In 2014 scientists confirmed that they were created some 40,000 years ago by blowing paint around appendages. In the 1950s, researchers discovered stalactite-like growths created with a pigment called red ochre to produce red and mulberry-colored paintings that formed over outlines of human hands. The Indonesian island Sulawesi, an hour north of the port of Makassar, is now believed to contain the earliest Paleolithic examples of man looking to express himself in an artistic manner. To fully understand the evolution of aerosol from its more utilitarian usages (which will be discussed later) to the preferred method of writing/ painting graffiti, one first has to recognize that, historically, man has been viewed as truly becoming human only after graduating to the use of expedited means of leaving his/her mark.
