Roland Clements Hanson, 75, died on August 28, 2009. His wife, Joan Acton Hanson, preceded him in death. Roland is survived by a sister, a brother, four children and four grandchildren. Roland received a B.S. in Engineering Physics at Michigan Technological University and a Ph.D. in Solid State Physics from the University of Illinois at Urbana-Champaign in 1960. After postdoctoral work at Cornell University, he joined the faculty at ASU in 1966, teaching and conducting research on the behavior of materials. He rose to full professor while helping pioneer the use of diamond anvil cells to create extraordinarily high pressures, and used sophisticated scattering and absorption techniques to measure their effects. He retired in 1999.
