Boise State University has received the largest gift in school history for scholarships, $1 million in stock and real estate from the estate of R.J. and Oressa McCaslin.

The couple started a lumber business in 1938 that eventually expanded to lumber yards in Idaho, Nevada, Oregon and Colorado.Roy McCaslin, who died in 1979, was active in Boise civic organizations and spent 25 years on the board of directors for Idaho First National Bank. His wife, a graduate of Southern Methodist University, was a teacher prior to her marriage in 1928. She died in 1987.

The BSU Foundation will invest the gift and use the proceeds to fund graduate assistantships for students in the College of Arts and Sciences studying geology, raptor biology, English and geophysics.

School President John Keiser said the gift should produce enough money to benefit generations of students.
