Tracy Hall, the physical chemist who h tracy hall the first reproducible process for making diamonds in the laboratory, kicking off a multibillion-dollar industry, died Friday at his home in Provo, h tracy hall, Utah. The feat, considered on a par with converting lead into gold, had been a globex 2000 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.

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.

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. I got a kick out of all the tinkering he had to do before he hit on the right contraption for cooking up diamonds: "Hall had built a pressure chamber that he called the "half-belt" that had been used to create high pressures in a year-old Watson-Stillman press that leaked so much water from its hydraulics that he had to wear rubber boots while working with it. My eyes had caught the flashing light from dozens of tiny. Fifty years later, it's still a thrill to create a diamond, a thrill we tried to capture in a story in the June issue of Smithsonian magazine. One of the barriers to publishing a story about diamond growers is that almost everyone involved is touchy about secrecy. Private companies want to protect their supersecret recipes--some combination of temperature, pressure and vaporized carbon--from competitors, and nobody knows how far the natural diamond powers will go to protect their market. Hall had his share of secrecy worries as well.

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. For the next two years, he served as an ensign in the U.

Tracy Hall. He always wanted to be a scientist at the General Electric Company, and began working toward this dream as a young fourth-grader. Hall stopped at nothing to achieve this dream and went on to work for General Electric Company. It was here that he played a large role in developing the synthetic diamond-making process — an invention that we now use every day when we use everyday objects like nail files, smart phones, and construction saws. Hall was grateful for the experiences he had as a child that helped him develop the skills he needed to eventually work at GE and develop the historic synthetic diamond.

A chemist who worked for General Electric, he and his colleagues somehow created a method that resulted in synthetic diamonds that were, by all accounts, exact duplicates of the real thing. Being a very intelligent man, he recognized this as a terrible insult, so he left the company and found another way to create synthetic diamonds for which he would hold the copyright. But while you have likely never heard of Dr. This technology has been used to supply the very diamonds that, for example are so frequently used in things like DVD players and computers and various other things that we take for granted in this day and age, including high-tech and life-saving medical equipment. Surely, he must have made out like a bandit for this incredible discovery, right? Unfortunately for Hall, that was not the case. So why was he shortchanged?

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.
