The <entity_0>, informally known as the <entity_2> <entity_1>, was an <entity_1> held in <entity_2>, <entity_4>, from April 30 to <entity_3>. In <entity_3>, <entity_2> hosted a <entity_1> to celebrate the centennial of the 1803 Louisiana Purchase. While initially conceived as a centennial celebration to be held in 1903, the actual opening of the <entity_2> exposition was delayed until <entity_3>, to allow for full-scale participation by more states and foreign countries. During the year of the fair, the <entity_0> supplanted the annual <entity_2> Exposition of agricultural, trade, and scientific exhibitions which had been held in the city since the 1880s. In 1901 the <entity_0> Corporation selected prominent <entity_2> architect Isaac S. Taylor as the Chairman of the Architectural Commission and Director of Works for the fair, supervising the overall design and construction. Florence Hayward, a successful freelance writer in <entity_2> in the 1900s, was determined to play a role in the <entity_1>. At the <entity_3> <entity_0>, many of the inventions displayed were precursors to items which have become an integral part of today's culture. In 1900, Gray's assistant, Foster Ritchie, improved upon the original design, and it was this device that was displayed at the <entity_3> <entity_1> and marketed for the next thirty years. X-ray machine – The X-ray machine was an invention that had its public debut at the <entity_3> <entity_1>. For the <entity_3> <entity_1>, the X-ray machine was perfected and successfully shown to the public. Airplane – The <entity_3> <entity_1> hosted the first-ever "Airship Contest" since aerial navigation was still in its infancy at this time. These areas controversially became unincorporated territories of the <entity_4> in 1899, and people were brought from these territories to be on "display" at the <entity_3> fair. The Fair hosted the <entity_3> Summer Olympic Games, the first Olympics held in the <entity_4>. The poet T. S. Eliot, who was born and raised in <entity_2>, visited the Igorot Village held in the Philippine Exposition section of the <entity_2> <entity_1>. Several months after the closing of the <entity_1>, he published a short story entitled "The Man Who Was King" in the school magazine of Smith Academy, <entity_2>, that he was attending. Jack Daniel, the <entity_4> distiller and the founder of Jack Daniel's Tennessee whiskey distillery, entered his Tennessee whiskey into the <entity_1> whiskey competition.
