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. But the federal government had slapped a secret label on the apparatus, which effectively prevented Hall from using it. His solution was to invent another apparatus, called the tetrahedral press, that was even better and that circumvented all the patents held by GE. He published his research in a widely read journal, but shortly thereafter, the government slapped a secret label on that device 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.

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? They naturally ignored the fact that Hall had been able to duplicate his process without the use of their expensive equipment, because sometimes you apparently just have to justify spending that much money to your shareholders who might otherwise wonder why on Earth you needed to buy the machine in the first place when your lead chemist was able to duplicate the process on his own equipment. However, his previous work had been patented by GE, so he actually came up with yet another way to create synthetic diamonds. Of course, that method was almost immediately deemed classified by the government, at least for a few months when they presumably realized he had been screwed over enough already and let him finish his research.

Her current research activities focus on software fault prediction and the development of tools for use by software engineers. 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.

Working with Mark Harman during sabbatical year. Her current research activities focus on software fault prediction and the development of tools for use by software engineers. Hall was one of a group of about a half dozen researchers who had focused on achieving the synthesis for almost four years. Over the last 20 years she has conducted many empirical software engineering studies with a variety of industrial collaborators. There he invented additional apparatus and products and founded several companies that manufacture diamonds and high-pressure equipment. Military Service: U. Hazen Her interests also include software testing and the human factors in relation to the developers producing code. She has published over international peer reviewed journal and conference papers and has won numerous best paper awards.
