Nathaniel Arbiter, Professor Emeritus of Columbia University, died Oct.5th at age 97, leaving multiple legacies of love, ethics, adventure and professionalism for family, friends, former students and colleagues.

Professor Arbiter was born Jan. 2, 1911 in Yonkers, NY to David and Ida Cora (Rockman) Arbiter.

He was one of seven siblings.

Educated as an undergraduate and graduate at Columbia, he came to Arizona in the 1940s, with Phelps-Dodge in Morenci.

Later, he joined the faculty of Columbia’s Henry Krumb School of Mines.

There, he began his global travels.

He took early retirement to join Anaconda in Tucson in 1968, quickly becoming Director of Research world wide, and later, Consulting Metallurgist.

He continued as a private consultant upon his second retirement.

For six decades he was a leader in metallurgical research: however, he considered his greatest success to lie in the accomplishments of the people he mentored in the classroom and the field of mineral processing.
