Raymond Rogers  Raymond N. Rogers (July 21, 1927 – March 8, 2005) was an American chemist who was considered a leading expert in thermal analysis. To the general public, however, he was best known for his work on the Shroud of Turin. Rogers was born in Albuquerque, New Mexico. At the University of Arizona he studied chemistry, receiving a BS in 1950. From 1951 to 1988 he was an explosives research expert and thermal analyst with the Los Alamos Scientific Laboratory (later called Los Alamos National Laboratory or LANL). From 1987 until 1992 he served on the Department of the Air Force Scientific Advisory Board with the equivalent rank of Lt. General and received a Distinguished Service Award. He received other awards and recognitions from LANL and many professional organizations. He was granted a sabbatical in 1968 to pursue post-graduate studies in archaeology. During his career Rogers published over forty peer-reviewed papers on chemistry. In 1981 he was named Laboratory Fellow at Los Alamos National Laboratory. Other honors included being named a Tour Speaker for the American Chemical Society in 1971, the Los Alamos National Laboratory Distinguished Performance Award in 1984, and the Department of the Air Force Exceptional Civilian Service Medal in 1991. He also served as the editor for "Energetic Materials," a peer-reviewed scientific journal, from 1983-1988. He was also on the editorial board of "Thermochimica Acta" from the first issue of this journal in 1970 (also the very first paper published in the first issue of this journal is authored by him) until his retirement in 1988. Rogers suffered from cancer. He died at his Los Alamos home on March 8, 2005. He was outlived by his wife, Joan, and his children. Rogers was appointed Director of Chemical Research for the Shroud of Turin Research Project (STURP) in 1978, applying thermal methods to the study of this relic. In recent years, he further researched material relevant to the dating of the Shroud, publishing his findings in "Thermochimica Acta." In 1978, the team of scientists conducted their testing over five days in Turin, Italy. Until Rogers's death in 2005, he continued to study the Shroud and explain the studies he had undertaken. He participated in ongoing discussions with the Shroud Science Group, a group of about 100 scientists, historians, and archeologists who continue to study the Shroud of Turin. Rogers's continual study of the Shroud resulted from a 2000 study by Joseph Marino and Sue Benford, based on x-ray analysis of the sample sites, showing a probable seam from a repair attempt running diagonally through the area from which the sample was taken.
