Howard Tracy Hall October 20, — July 25, was an American physical chemist and one of the early pioneers in the research of synthetic diamondsusing 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, dr tracy hall, Tracy Hall.

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.

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. Back to Inductee Search H.

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.

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?

He co-founded MegaDiamond in , and later was involved with the founding of Novatek, both of Provo, Utah. Find an Inductee. He transferred the technology for the cubic press system to China in about , and today the vast majority of the world's synthetic diamond powder is produced using the many thousands of cubic presses of Hall's design presently operating in that country. Professor Hall is a highly experienced academic. Accept optional cookies Reject optional cookies. Download as PDF Printable version. ISBN The composition of the starting material in the sample chamber, catalyst for the reaction, and the required temperature and pressure were little more than guesses. 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. Working with Mark Harman during sabbatical year.

At BYU, he invented the tetrahedral and cubic press systems. Previous Slide Next Slide. Tracy Hall knew, with the clarity of a chemist, that diamonds are diamonds, and diamonds are carbon. Her interests also include software testing and the human factors in relation to the developers producing code. Born Oct. He had seven children, 35 grandchildren and 53 great-grandchildren. 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 was a descendant of Mormon pioneers and grew up on a farm in Marriott, Utah. Get the latest Science stories in your inbox.
