The origin of the concept of "state-of-the-art" took place in the beginning of the twentieth century. The earliest use of the term "state-of-the-art" documented by the Oxford English Dictionary dates back to 1910, from an engineering manual by Henry Harrison Suplee (1856 – post 1943), an engineering graduate (University of Pennsylvania, 1876), titled "Gas Turbine: progress in the design and construction of turbines operated by gases of combustion". The relevant passage reads: "In the present state-of-the-art this is all that can be done". The term "art" refers to technics, rather than performing or fine arts.
