sentences: The Eddington Medal is awarded by the Royal Astronomical Society for investigations of outstanding merit in theoretical astrophysics.
 It is named after Sir Arthur Eddington.
 First awarded in 1953, the frequency of the prize has varied over the years, at times being every one, two or three years.
 Since 2013 it has been awarded annually.
Stephen Herbert Hymer (15 November 1934 – 4 February 1974) was a Canadian economist.
 His research focused on the activities of multinational firms, which was the subject of his PhD dissertation "The International Operations of National Firms: A Study of Direct Foreign Investment", presented in 1960, but published posthumously in 1976, by the Department of Economics from Massachusetts Institute of Technology.
 Charles P. Kindleberger, his thesis supervisor, submitted it for publication, as mentioned by him on the introduction of Hymer's thesis dissertation.
Leon Mestel (5 August 1927 – 15 September 2017) was a British astronomer and astrophysicist and Emeritus Professor at the University of Sussex.
 His research interests were in the areas of star formation and structure, especially stellar magnetism and astrophysical magnetohydrodynamics.
 He was awarded both the Eddington Medal (1993) and the Gold Medal of the Royal Astronomical Society (for Astronomy, 2002).
 Following his retirement, he wrote several obituaries and biographical articles on physicists and astrophysicists.
Van A. Harvey is George Edwin Burnell Professor of Religious Studies (Emeritus) at Stanford University.
 Born in Hankow, China, he served in the U.S. Navy (1943–46), and was awarded a BA in Philosophy from Occidental College (1948, Phi Beta Kappa).
 After attending Princeton Theological Seminary for one year, he received a B.D. from Yale Divinity School in 1951 and a PhD.
 from Yale University in 1957 in post-Enlightenment religious thought.
 His thesis was entitled "Myth, Faith, and History" and his thesis supervisor was H. Richard Niebuhr.
Herbert Friedman (June 21, 1916 – September 9, 2000) was an American pioneer in the application of sounding rockets to solar physics, aeronomy, and astronomy.
 He was also a statesman and public advocate for science.
 During his lifetime, he was awarded the Eddington Medal of the Royal Astronomical Society, the National Medal of Science, the Henry Norris Russell Lectureship of the American Astronomical Society, the William Bowie Medal of the American Geophysical Union, the Wolf Foundation Prize in Physics, and the Albert A. Michelson Medal of the Franklin Institute (1972), among others.
 He was elected a member of the National Academy of Sciences in 1960 and of the American Philosophical Society in 1964.
PSR B1919+21 is a pulsar with a period of 1.3373 seconds and a pulse width of 0.04 seconds.
 Discovered by Jocelyn Bell Burnell and Antony Hewish on November 28, 1967, it is the first discovered radio pulsar.
 The power and regularity of the signals were briefly thought to resemble an extraterrestrial beacon, leading the source to be nicknamed LGM-1 (for "little green men").
Antony Hewish FRS (born 11 May 1924 in Fowey, Cornwall) is a British radio astronomer who won the Nobel Prize for Physics in 1974 (together with fellow radio-astronomer Martin Ryle) for his work on the development of radio aperture synthesis and its role in the discovery of pulsars.
 He was also awarded the Eddington Medal of the Royal Astronomical Society in 1969.
Dame Susan Jocelyn Bell Burnell, (born 15 July 1943) is a Northern Irish astrophysicist.
 As a postgraduate student, she discovered the first radio pulsars while studying and advised by her thesis supervisor Antony Hewish, for which Hewish shared the Nobel Prize in Physics with astronomer Martin Ryle.
 Bell Burnell was excluded, despite having been the first to observe and precisely analyse the pulsars.
 Bell Burnell was President of the Royal Astronomical Society from 2002 to 2004, president of the Institute of Physics from October 2008 until October 2010, and was interim president following the death of her successor, Marshall Stoneham, in early 2011.
 She was succeeded in October 2011 by Sir Peter Knight.
 Bell Burnell was elected as President of the Royal Society of Edinburgh in October 2014.
 In March 2013 she was elected Pro-Chancellor of the University of Dublin.
Paul Ledoux (August 8, 1914 – October 6, 1988) was a Belgian astrophysicist, best known for his work on stellar stability and variability.
 With Theodore Walraven, he co-authored one of the seminal works on stellar oscillations.
 In 1964 Paul Ledoux was awarded the Francqui Prize for Exact Sciences.
 He was awarded the Eddington Medal of the Royal Astronomical Society in 1972 for investigations into problems of stellar stability and variable stars.
 He was awarded the Janssen Medal of the French Academy of Sciences in 1976.
Sir John Peebles Arbuthnott, PPRSE, FRCPSG, FMedSci, FRCPath (born 8 April 1939) is a Scottish microbiologist, and was Principal of the University of Strathclyde.
 He succeeded Lord Wilson of Tillyorn as President of The Royal Society of Edinburgh in October 2011 and was succeeded by Dame Jocelyn Bell Burnell in October 2014.
