1905: An Industry Is Born
In 1905, the city of Portland, Oregon was getting ready to host a World�s Fair as part of the 100th anniversary celebration of the Lewis and Clark Expedition. Several local businesses were asked to prepare exhibits for the event, including Portland Manufacturing Company, a small wooden box factory in the St. Johns district of the city. Part owner and plant manager Gustav Carlson decided to laminate wood panels from a variety of Pacific Northwest softwoods. Using paint brushes as glue spreaders and house jacks as presses, several panels were laid up for display. Called �3-ply veneer work,� the product created considerable interest among fairgoers, including several door, cabinet and trunk manufacturers who then placed orders. By 1907, Portland Manufacturing had installed an automatic glue spreader and a sectional hand press. Production soared to 420 panels a day. And an industry was born.
