Dr. William Stanley Murray (1887-1972) was born in Stillson Hill, Warren County, Pa., just across the New York state line from Chautauqua County, the westernmost county in New York. He was the son of George Campbell, who was engaged in the oil production business, and Armeina (Kay) Murray. Dr. Murray matriculated at

"We just turned him loose to investigate, because he seemed happy to tackle new and untried problems." Dr. Murray graduated with a bachelor's of science degree in 1910. He joined the university's board of trustees in 1926, and on October 15, 1939, Dr. Murray was awarded a

) – began working independently, and at times together, to study indium in hopes of discovering ways to process and use it for a variety of solutions in everyday life. When they first looked into indium as a valuable stabilizing element, four elementary textbooks were examined. Only one of them listed the element, and it mentioned indium as being "'a member of the aluminum family' and dismissed the subject." Dr. William Stanley Murray, director of research, and Technologist Daniel Gray soon began to research and devise multiple processes to alloy,

Beebe, in the Cerbat Mining District near Kingman, Dr. Murray led the search and found indium in a viable quantity to be commercially produced. The property was purchased by Dr. Murray in 1926 and later transferred to Indium Corporation of America. Initially, the combined search effort by Dr. Murray, the Salt Lake City Bureau of Mines' staff, and Anaconda Mining Co. staff led to the discovery of 35,000 tons of indium-rich ore that was blocked out. In 1927, of 1,000 tons of zinc ore mined in Kingman, 250 ounces of indium was produced (0.78 percent). Initial

That settled the matter and the government officials quickly realized he knew what he was talking about." Between 1926 and 1934, either Drs. Murray or Gray were named on all U.S. patent applications applied for and issued related to indium: they co-authored four patent applications; additionally, Dr. Murray submitted four solo applications and Daniel submitted three. These include a process to produce tarnish-resisting silver and silver plate and a process to obtain indium and zinc from ore (1932). Richard Orcutt Bailey, also employed at Oneida Community during the time period of 1926–1934, was also listed as an inventor of a number of patents with Dr. Murray and Gray, a majority of them involving a method of producing tarnish-resisting

"Interest in indium and requests for experimental work … expanded so greatly, the establishment of a laboratory in New York became imperative." A new development laboratory to address requests from both industry and various government agencies was established in 1941 at the Electrical Testing Laboratories, East End Avenue at 79th St., New York, N.Y. Work at the new lab is commissioned by the U.S. Bureau of Conservation of Materials and includes the production of hundreds of samples for varied industries, including bearings for machinery, piston rings, valves for industrial pumps, bushings and other moving parts for machinery, as well as "hot-dip" coatings for metallic surfaces. Total domestic output of indium in 1941 was approximately 21,700

Indium Corporation was the principal distributor of indium in the U.S., and the Anaconda Copper Mining Co. led all indium production from zinc and lead operations. In 1942, electrolytic-grade indium (99.9 percent pure) was $30 per ounce. William "Mac" N. Macartney, III (1941-2021) was born on December 16, 1941, in Utica, the son of William N.

(The bright trim on completed cars still in stock had to be painted over.) … In order to provide vehicles that would approximate the beauty of their more glittery predecessors, Studebaker did much research on the use of non-critical metals like indium silver, and utilized baked-enamel finishes in colors that would offer pleasing contrast to that of the body." The majority of indium produced between 1942 and 1945 was used in the war effort. J. Robert Dyer, Jr.'s process to plate bearings with indium would lead the company's production through 1945. Dyer said the Pratt & Whitney Aircraft Co. approached the Indium Corporation in 1938 for help identifying a protective plating treatment for bearings. "It turned out that indium-plated bearings were so much better than any others at the time, they were specified for
