About Tracy Hall

Howard Tracy Hall was an American physical chemist and one of the early pioneers in the research of synthetic diamonds, using a press of his own design. Hall returned to the University of Utah in 1946, where he was Henry Eyring's first graduate student, and was awarded his PhD in physical chemistry in 1948. In the early 1960s, Hall invented the first form of polycrystalline diamond (PCD). At BYU, he invented the tetrahedral and cubic press systems.
