Question: Owen Chamberlain's collaborator was awarded the Nobel Prize in what year?

Context paragraphs:
Leverhulme Medal (Royal Society): The Leverhulme Medal is awarded by the Royal Society every three years "for an outstandingly significant contribution in the field of pure or applied chemistry or engineering, including chemical engineering".  It was created in 1960 after a donation by the Leverhulme Trust to mark the 300-year anniversary of the foundation of the Royal Society, and is accompanied by a £2000 gift.  Since its creation it has been awarded 17 times, and unlike other Royal Society medals such as the Royal Medal, it has never been awarded to a woman or to the same person multiple times.  Citizens of the United Kingdom have won the medal 16 out of the 17 times; the only foreign recipient was Man Mohan Sharma, an Indian citizen who was awarded the medal in 1996 "for his work on the dynamics of multi-phase chemical reactions in industrial processes".  Two of the Leverhulme Medal winners also won the Nobel Prize in Chemistry: Archer John Porter Martin, who won the medal in 1963 for "his distinguished and fundamental discoveries in chromatography and its application" and the Nobel Prize in 1952, and Cyril Norman Hinshelwood, who won the medal in 1960 for "his outstanding contributions to physical chemistry" and the Nobel Prize in 1956.

Nobel Prize in Physics: The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics.  It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

List of Nobel laureates in Chemistry: The Nobel Prize in Chemistry (Swedish: "Nobelpriset i kemi" ) 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 1895 will of Alfred Nobel, who died in 1896.  These prizes are awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine.  As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members elected by the Royal Swedish Academy of Sciences.  The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands.  Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years.  In 1901, van 't Hoff received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007.  The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death.

List of Nobel laureates in Physiology or Medicine: The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine.  It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine.  As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute.  While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will.  Because of this, the prize can be awarded in a broader range of fields.  The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany.  Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years.  In 1901, von Behring received 150,782 SEK, which is equal to 7,731,004 SEK in December 2008.  In 2013, the prize was awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof; they were recognised "after discovering how cells precisely transport material".  The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death.

Ray David Owen: Ray David Owen (October 30, 1915 – September 21, 2014) was a teacher and scientist whose discovery of unusual, “mixed,” red blood cell types in cattle twins in 1945 launched the fields of modern immunology and organ transplantation.  Owen’s 1945 findings were published in the journal "Science".  This observation demonstrated that self was “learned” by the immune system during development and paved the way for research involving induction of immune tolerance and early tissue grafting.  When Frank Macfarlane Burnet and Sir Peter Brian Medawar were awarded their 1960 Nobel Prize in Physiology or Medicine for the discovery of acquired immunological tolerance, Owen was not mentioned in the prize.  However, in a letter to Owen, Medawar stated that he believed Owen should have also been included in the prize.  Owen also led the successful effort to admit women as California Institute of Technology (or Caltech) undergraduates.

Emilio Segrè: Emilio Gino Segrè (1 February 1905 – 22 April 1989) was an Italian physicist and Nobel laureate who discovered the elements technetium and astatine, and the antiproton, a sub-atomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959.

Bevatron: The Bevatron was a particle accelerator — specifically, a weak-focusing proton synchrotron — at Lawrence Berkeley National Laboratory, U.S., which began operating in 1954.  The antiproton was discovered there in 1955, resulting in the 1959 Nobel Prize in physics for Emilio Segrè and Owen Chamberlain.  It accelerated protons into a fixed target, and was named for its ability to impart energies of billions of eV.  (Billions of eV Synchrotron.)

Owen Chamberlain: Owen Chamberlain (July 10, 1920 – February 28, 2006) was an American physicist, and Nobel laureate in physics for his discovery, with collaborator Emilio Segrè, of the antiproton, a sub-atomic antiparticle.

Nobel Prize in Literature: Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstående verket i en idealisk riktning").  Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole.  The Swedish Academy decides who, if anyone, will receive the prize in any given year.  The academy announces the name of the chosen laureate in early October.  It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

The first Nobel Prize in Literature was awarded in 1901 to Sully Prudhomme of France.  Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years.
