James Krieble died Oct. 25, 2012, at Kendal in Hanover, N.H.
Jim grew up in Union City, N.J., where his father, I.R. Krieble 1908, was principal of the Robert Waters School. After attending public schools in Union City, Jim spent his last year of high school at Lawrenceville.
At Princeton, Jim majored in chemical engineering. He was a member of the Engineering Society and Dial Lodge and graduated with honors. Shortly after graduation he married Amanda Sanborne.
During World War II, Jim was a lieutenant junior grade serving at the Naval laboratory in Washington, D.C. After his discharge he returned to Princeton and earned a Ph.D. in chemical engineering.
Jim spent his postwar career as an engineer at General Electric. Initially he worked at the research laboratory in Schenectady, focusing on projects dealing with tungsten chemistry, the iodide process, and the electrolytic oxidation of metals. In 1957 he moved to the lamp, metals, and components department in Cleveland. During this time a series of scientific papers attested to his participation in advances in this field. Ultimately he became a plant manager, simultaneously working on improvements in the science of lighting.
Jim was predeceased by Amanda. To their daughters, Cynthia and Elizabeth; son John ’74; and their four grandchildren, the class sends condolences.
