Industrialist, Mining Executive. A native of Missouri, Jackling was raised by his aunt after having lost both of his parents by the age of two. In 1892 he graduated from the Missouri School of Mines and returned the next year to serve as an assistant professor of Chemistry and Metallurgy. After working as a miner for a few years, he made his way to Utah in 1896 where he worked as a mine superintendent. In 1903 he founded the Utah Copper Company, which he became Vice-President and General Manager of, and began work at Bingham Canyon, a site that was considered by many to be worthless due to the low-grade copper it produced. To deal with the poor copper, he pioneered using mass production methods, including the use of open pit mining and steam shovels, which allowed him to process much more copper in a shorter time. By the time of his death, the methods he pioneered were producing 60% of the world’s copper. From 1903 until 1904 he served as a Colonel on the staff of Colorado Governor James H. Peabody and later also served on the staff of Utah Governor William Spry. With the entry of the United States into World War One, he was appointed director of United States Government Explosives Plants and would receive the Distinguished Service Medal in 1919 for his service.
