Alaska–Yukon–Pacific Exposition

The Alaska–Yukon–Pacific Exposition was a world's fair held in Seattle in 1909, publicizing the development of the Pacific Northwest.

It was originally planned for 1907, to mark the 10th anniversary of the Klondike Gold Rush, but the organizers found out about the Jamestown Exposition being held that year, and rescheduled.

The fairgrounds became the campus of the University of Washington.

The fair was evolved from an idea of Godfrey Chealander's. Chealander, then Grand Secretary of the Arctic Brotherhood, was involved in the Alaska Territory exhibit at the 1905 Lewis and Clark Exposition in Portland, Oregon. Originally, he pitched William Sheffield of the Alaska Club and James A. Wood, city editor of the Seattle Times on the idea of a permanent exhibit in Seattle about Alaska. This merged with Wood's desire for an exposition to rival Portland's. They soon gained the backing of Times publisher Alden J. Blethen—remarkably, for the time, without gaining the opposition of the rival Seattle Post-Intelligencer.

Edmond S. Meany proposed that the exposition be held on the then largely forested campus of the University of Washington, which in 1905 had exactly three buildings and little deliberate landscaping. At the time, this was considered rather far from the center of town, but Meany eventually sold the others involved on the idea that the forested campus could, itself, be an attraction for out-of-town visitors and that the trolley ride from downtown would not be an obstacle to attendance. Of course, he was also highly aware of what the landscaping and structures could do for the campus.
