Q: Context: Frederick Sanger OM CH CBE FAA ( / sær / ; 13 August 1918 -- 19 November 2013 ) was a British biochemist who won the Nobel Prize for Chemistry twice , one of only two people to have done so in the same category ( the other is John Bardeen in Physics ) , the fourth person overall with two Nobel Prizes , and the third person overall with two Nobel Prizes in the sciences . In 1958 , he was awarded a Nobel Prize in chemistry `` for his work on the structure of proteins , especially that of insulin '' . In 1980 , Walter Gilbert and Sanger shared half of the chemistry prize `` for their contributions concerning the determination of base sequences in nucleic acids '' . The other half was awarded to Paul Berg `` for his fundamental studies of the biochemistry of nucleic acids , with particular regard to recombinant DNA '' ., John Bardeen (May 23, 1908  January 30, 1991) was an American physicist and electrical engineer, the only person to have won the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory., Paul Berg (born June 30, 1926) is an American biochemist and professor emeritus at Stanford University. He was the recipient of the Nobel Prize in Chemistry in 1980, along with Walter Gilbert and Frederick Sanger. The award recognized their contributions to basic research involving nucleic acids. Berg received his undergraduate education at Penn State University, where he majored in biochemistry. He received his Ph.D. in biochemistry from Case Western Reserve University in 1952. Berg worked as a professor at Washington University School of Medicine and Stanford University School of Medicine, in addition to serving as the director of the Beckman Center for Molecular and Genetic Medicine. In addition to the Nobel Prize, Berg was presented with the National Medal of Science in 1983 and the National Library of Medicine Medal in 1986. Berg is a member of the Board of Sponsors for the "Bulletin of the Atomic Scientists"., Alfred Bernhard Nobel (21 October 1833  10 December 1896) was a Swedish chemist, engineer, inventor, businessman, and philanthropist., The Nobel Prize in Chemistry is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895, awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. This award is administered by the Nobel Foundation and awarded by Royal Swedish Academy of Sciences on proposal of the Nobel Committee for Chemistry which consists of five members elected by Academy. The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands, "for his discovery of the laws of chemical dynamics and osmotic pressure in solutions.", Washington University School of Medicine (WUSM), located in St. Louis, Missouri, is the medical school of Washington University in St. Louis on the eastern border of Forest Park in St. Louis. Founded in 1891, the School of Medicine has 1,260 students, 604 of which are pursuing a medical degree with or without a combined Doctor of Philosophy or other advanced degree. It also offers doctorate degrees in biomedical research through the Division of Biology and Biological Sciences. The School has developed large physical therapy (273 students) and occupational therapy (233 students) programs, as well as the Program in Audiology and Communication Sciences (75 students) which includes a Doctor of Audiology (Au.D.) degree and a Master of Science in Deaf Education (M.S.D.E.) degree. There are 1,772 faculty, 1,022 residents, and 765 fellows., Subject: frederick sanger, Relation: academic_degree, Options: (A) doctor of philosophy (B) engineer (C) master of science (D) professor
A:
doctor of philosophy
