Howard Tracy Hall October 20, — July 25, was an American physical chemist and one of the early pioneers in the research of synthetic diamondsdr tracy hall, using a press of his own design.

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.

Professor Hall's main research interests are in software engineering. In particular in the analysis of code and the detection, prediction and repair of defects in code. She is particularly intersted in automatic approaches to defect repair. Her interests also include software testing and the human factors in relation to the developers producing code. In particular the errors developers make that result in faults in code. Over the last 20 years she has conducted many empirical software engineering studies with a variety of industrial collaborators. Her current research activities focus on software fault prediction and the development of tools for use by software engineers. She has published over international peer reviewed journal and conference papers and has won numerous best paper awards. She has contributed to various conference organizing committees and is a long standing member of many international conference programme committees. Professor Hall is a highly experienced academic. She has delivered many different Computer Science subjects to undergraduate and postgraduate students.

But the federal dr tracy hall had slapped a secret label on the apparatus, which effectively prevented Hall from using it. 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. Howard Tracy Hall was born in Ogden, Utah in

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.

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?

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.

July 25, aged 88 Provo, Utah , U. Tracy Hall, along with Francis Bundy, Robert Wentorf, and Herbert Strong, had synthesized diamond from carbon in a process that was reproducible. GE went on to make a fortune with Hall's invention. He died last week at age Tools Tools. She is particularly intersted in automatic approaches to defect repair. He "bootlegged" the machining of the first hardened steel version of this press, which showed some promise, and eventually got management to approve the construction of it in the tougher, much more expensive Carboloy tungsten carbide dispersed in cobalt, also known as Widia. He joined a team focused on synthetic diamond making, codenamed "Project Superpressure" headed by engineer Anthony Nerad.
