Tracy Hall, along with Francis Bundy, Robert Wentorf, and Herbert Strong, had synthesized diamond from carbon in a process that was reproducible.

Howard Tracy Hall October 20, — July 25, was an American physical chemist and one of the early pioneers in the research of synthetic diamonds , using a press of his own design. Howard Tracy Hall was born in Ogden, Utah in He often used the name H. Tracy Hall or, simply, Tracy Hall. He was a descendant of Mormon pioneers and grew up on a farm in Marriott, Utah. When still in the fourth grade, he announced his intention to work for General Electric.

Tracy Hall, the physical chemist who invented the first reproducible process for making diamonds in the laboratory, kicking off a multibillion-dollar industry, died Friday at his home in Provo, Utah. The feat, considered on a par with converting lead into gold, had been a goal of chemists, alchemists, physicists and scam artists for more than two centuries when Hall -- ostensibly part of a team at General Electric but working primarily on his own -- pulled it off. Those first diamonds were small to the point of near invisibility and nowhere near the quality that might be required for jewelry. But they were perfect for a variety of industrial applications that involved cutting, grinding and polishing a range of once-intractable materials. The material is also finding growing use in the electronics industry and, as new techniques have allowed the production of stones as large as 12 carats, in the jewelry business as well. Hall should have received a Nobel Prize for his work, said earth scientist Robert M. Hazen of George Mason University, author of a book about the creation of the man-made diamond industry. The search for artificial diamonds was triggered by the discovery that a diamond is a form of pure carbon, converted into crystalline form by high temperatures and pressures. Over the centuries, researchers tried various clever ways of producing the desired conditions, occasionally claiming the production of one or more stones. But their work was never reproducible, and most observers argued that the stones had been secretly added to the experiments by sympathetic colleagues or by the researchers themselves. He persuaded a friend in the shop to do the work during off hours, and a former supervisor persuaded the company to purchase the expensive carboloy tungsten carbide dispersed in cobalt that he needed to produce it. After several false starts, Hall ran a final test in the new device on Dec. My eyes had caught the flashing light from dozens of tiny. Hall repeated the experiment several times, achieving the same results. A week later, Hall reported his results to GE officials, who suspected that he was exaggerating his findings.

He co-founded MegaDiamond inand later was involved with the founding of Novatek, both of Provo, Utah. Born Oct.

Diamonds are the subject of one of the great battles between the forces of Marketing and the forces of Matter. In one corner is DeBeers, with the best advertising slogan of the 20th Century , "Diamonds are Forever. Tracy Hall was the first guy to turn carbon into diamonds. He died last week at age The L. Times has the best obituary of Hall that I've seen.

Collection primarily documents Hall's career as a chemist and includes personal research notes, drawings, blueprints, and photos, publications and drafts, research proposals and reports, technical information, and patents, as well as incoming and outgoing correspondence and administrative information regarding Brigham Young University, General Electric, Megadiamond Corporation, and other professional, community, and civic societies in which Hall was involved. It also includes personal information such as personal and family history, correspondence, early academic details, family finances, and legal information. Materials date from between and It is the responsibility of the researcher to obtain any necessary copyright clearances. Permission to publish material from the H.

Tracy Hall, creator of the man-made industrial diamond, passed away at his home early on the morning of July He was As a young man he roamed the fields of Marriott, Utah, read avidly at the Ogden Carnegie Library, and assembled home-made contraptions from junk-yard components. As a fourth grader he told his teacher he would someday work for General Electric, the company so closely associated with his hero, inventor Thomas Edison. After completing his B. Returning to the University of Utah in , he became Henry J. At GE, Hall joined a team focused on synthesizing diamonds in the laboratory. On December 16, , he became the first person to produce diamond from carbon using a verifiable and reproducible process. My hands began to tremble; my heart beat rapidly; my knees weakened and no longer gave support—I knew that diamonds had finally been made by man. Hall eventually became Director of Research at Brigham Young University in , and over his 30 years at BYU, where he was a highly regarded professor of chemistry and mentor of many graduate students.

But H. Maugh II. Tracy Hall knew, with the clarity of a chemist, that diamonds are diamonds, and diamonds are carbon. But their work was never reproducible, and most observers argued that the stones had been secretly added to the experiments by sympathetic colleagues or by the researchers themselves. The feat, considered on a par with converting lead into gold, had been a goal of chemists, alchemists, physicists and scam artists for more than two centuries when Hall -- ostensibly part of a team at General Electric but working primarily on his own -- pulled it off. A few months later, however, the military lifted the veil of secrecy, and he was finally able to use the fruits of his labor. Archived from the original on Today, over tons or over million carats of synthetic diamonds are produced annually for industrial use. Hall produced synthetic diamond in a press of his own design [2] on December 16, , and showed that he and others could repeat the process following Hall's procedure, a success which led to the creation of a major supermaterials industry. Howard Tracy Hall was born in Ogden, Utah in Born Oct. Plan Your Visit Exhibits. American chemist.

Tracy Hall, along with Francis Bundy, Robert Wentorf, and Herbert Strong, had synthesized diamond from carbon in a process that was reproducible.

But when the experiment was repeated in front of them -- with Hall safely out of the building -- the results were the same. More From the Los Angeles Times. Ogden, Utah , U. De Los. The L. The official "shush" didn't last long, though, and Hall started his own company and kept making diamonds. He published his research in a widely read journal, but shortly thereafter, the government slapped a secret label on that device as well. Scientists knew that graphite, a pure carbon substance, was needed to produce manmade diamonds. Hall should have received a Nobel Prize for his work, said earth scientist Robert M. Originally from Ogden, Utah, Hall received his B. March 7, The feat, considered on a par with converting lead into gold, had been a goal of chemists, alchemists, physicists and scam artists for more than two centuries when Hall -- ostensibly part of a team at General Electric but working primarily on his own -- pulled it off. Born Oct. Hall returned to the University of Utah in , where he was Henry Eyring 's first graduate student, and was awarded his PhD in physical chemistry in Hall left GE in and became a full professor of chemistry and director of research at Brigham Young University.
