Diamonds are the subject of one of the great battles between the forces of Marketing and the forces of Matter.

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, along with Francis Bundy, Robert Wentorf, and Herbert Strong, had synthesized diamond from carbon in a process that was reproducible. Scientists knew that graphite, a pure carbon substance, was needed to produce manmade diamonds. The GE researchers discovered that graphite was resistant to change due to strong bonding of the carbon atoms. By utilizing iron as a catalyst to free the carbon bonds and by applying high pressure and high temperature, they were able to turn graphite into manmade diamonds. The first successful reproducible experiment was completed on the morning of December 16, by Hall in his unique "Belt" apparatus. Diamonds have a wide variety of applications because of their exceptional physical characteristics, including hardness and heat conductivity, making them ideal for use in cutting, grinding, and polishing. Today, over tons or over million carats of synthetic diamonds are produced annually for industrial use. Originally from Ogden, Utah, Hall received his B. There he invented additional apparatus and products and founded several companies that manufacture diamonds and high-pressure equipment. Plan Your Visit Exhibits.

Tracy Hall Diamond Synthesis. March 1,

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.

Tracy Hall, the father of man-made diamond, passed away on Friday the 25th of July at the age of As a young man Tracy roamed the fields of Marriott, Utah, read avidly at the public 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 Eyring's first graduate student, completing his PhD in While at GE Tracy joined a team focused on synthesizing diamond in the laboratory. On December 16, Tracy had the privilege of becoming the first person to produce diamond from carbon using a verifiable and reproducible process. Of the experience Dr. Hall later recalled "My eyes caught the flashing light from dozens of tiny crystals. 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.

However, scientists only realized that diamonds are the crystallized form of carbon in when Antoine Lavoisier made the discovery. Born in in Ogden, Utah, Hall grew up in nearby Marriott. His family were members of the Mormon Church and lived on a farm far enough from town that heading there for supplies meant the whole family went along for the ride. Hall and his brothers waited at the Ogden City Library for their parents to finish their business. There Hall learned about Thomas Edison and quickly became fascinated by the inventor. World War II interrupted his course of education.

A few months later, however, the military lifted the veil of secrecy, and he was finally able to use the fruits of his labor. Originally from Ogden, Utah, Hall received his B. He published his research in a widely read journal, but shortly thereafter, the government slapped a secret label on that device as well. Get the latest Science stories in your inbox. Military Service: U. Special Supplements. A week later, Hall reported his results to GE officials, who suspected that he was exaggerating his findings. Howard Tracy Hall was born Oct. Tools Tools. Hall had his share of secrecy worries as well. ISBN Weber State University College of Science. Toggle limited content width. 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.

March 6, Diamonds have a wide variety of applications because of their exceptional physical characteristics, including hardness and heat conductivity, making them ideal for use in cutting, grinding, and polishing. Scientists knew that graphite, a pure carbon substance, was needed to produce manmade diamonds. Hall's success, in his telling of the story, came about because of his determination to go his own way with a radical redesign of the press, which employed a doughnut-shaped die surrounded by shrink-fit steel sleeves the belt which confined the sample chamber and two curved and tapered pistons which pressed on the sample chamber. After the war, he returned to Utah for his doctorate and ultimately persuaded GE to hire him. Times Store. July 25, aged 88 Provo, Utah , U. Later he served a church mission to southern Africa with his wife, Ida-Rose Langford. More From the Los Angeles Times. Tracy Hall or, simply, Tracy Hall. Over the centuries, researchers tried various clever ways of producing the desired conditions, occasionally claiming the production of one or more stones.
