On the evening of February 9, 1923, a group of educators and scientists met in the Davenport Hotel in Spokane, Washington.  A committee developed plans to form an organization "of broad and general character designed to embrace all persons in the Inland Empire interested in the objectives of a regional scientific association."

The 1st Program Meeting took place in Spokane, WA from April 11-12 of 1924, in conjunction with the Inland Empire Teacher's Association.  Forty-five papers and 5 general session lectures were presented in 6 sections:  Botany-Zoology, Chemistry-Physics, Education, Geology-Geography, Medicine-Bacteriology, and Plant Pathology.  There were 45 charter-members of the Association and the annual dues were set at $1.00.
