SPRAGGETT ON CHESS

Professor Penrose (1898-1972) was an eminent geneticist and, in the chess world, a respected player and problemist. He was the father of Grandmaster Jonathan Penrose.

**THE PENROSE FAMILY**

*The Penrose family was an academically brilliant family. Oliver was a strong player in his youth and has recently started playing again in Scotland! There is a third brother,*

**Sir Roger Penrose**, a distinguished physicist.*Jonathan (a professional psychologist and university teacher) confined his chess mostly to winning the British Championship (ten times!) and playing in team tournaments (two olympiad silver medals on board 1 for England).*

*His win against Tal is probably his best known game, but he beat many of the strong players of his day, ranging from Bogoljubow and Tartakower (!) to Panno, Portisch and Mecking, and he even drew with Fischer. *

*At his best, his style was direct and incisive, somewhat like that of John Nunn. Jonathan suffered a lot with his nerves and after the Nice Olympiad he played less and less over the board, turning to correspondence chess instead.*

*FIDE awarded him the over-the-board GM title retrospectively – see letter by Leonard Barden*at http://www.ecforum.org.uk/viewtopic.php?f=27&t=632&start=15 ”

**I did some**

*on-line*digging into the Penrose family, and all I can say is that I am amazed! What a brilliant family…to say the least!THE FATHER

**Professor Penrose** (1898-1972) was an eminent geneticist and, in the chess world, a respected player and problemist.

**From his wikipedia entry:**

*“Professor Penrose and his associates have been responsible over the years for studies which touch all aspects of human genetics, include genetic analyses of most of the known hereditary diseases, contributions to mathematical genetics, biochemical genetics, the study of gene linkage in man, and theoretical work on the mutagenic effect of ionizing radiations. Most recently their attention has been turned to abnormalities of human chromosomes associated with congenital defects, particularly mongolism (Down syndrome).”*

**‘Penrose’s Law’**states that the population size of prisons and psychiatric hospitals are inversely related, although this is generally viewed as something of an oversimplification.

Penrose, a member of the Society of Friends (Quakers), was a lead figure in the Medical Association for the Prevention of War in the 1950s.

Penrose developed the **Penrose Method**, a method for apportioning seats in a global assembly based on the square root of each nation’s population. Such a voting system is based on the Penrose square root law, which states that the voting power of any voter (measured by the Penrose-Banzhaf index) decreases with the size of the voting body as one over its square root.”

………………………………………………………………………………………**THE THREE SONS:**

**From his wikipedia entry:**

**”Oliver Penrose**(born 1929) is a British mathematician. He is the son of the scientist Lionel Penrose, brother of the mathematical physicist Roger Penrose, and brother of chess master Jonathan Penrose.

**Sir**Roger Penrose (b.1931)

**From his own pen**:

**”Roger Penrose**, a professor of mathematics at the University of Oxford in England, pursues an active interest in recreational math which he shared with his father. While most of his work pertains to relativity theory and quantum physics, he is fascinated with a field of geometry known as tessellation, the covering of a surface with tiles of prescribed shapes.

**Wolf Prize**for Physics in 1988 which he shared with

**Stephen Hawking.**”

**From his wikipedia entry:**

”Sir Roger Penrose, OM, FRS (born 8 August 1931) is an English mathematical physicist and Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute, University of Oxford and Emeritus Fellow of Wadham College. He is renowned for his work in mathematical physics, in particular his contributions to general relativity and cosmology. He is also a recreational mathematicianand amateur philosopher.”

**His list of awards is amazing and I can not resist putting it in full. It looks as though somebody invented it, but it is indeed true:**

**Fellow of the Royal Society of London**in 1972. In 1975, Stephen Hawking and Penrose were jointly awarded the

**Eddington Medal of the Royal Astronomical Society**. In 1985, he was awarded the

**Royal Society Royal Medal**. Along with Stephen Hawking, he was awarded the prestigious

**Wolf Foundation Prize for Physics**in 1988. In 1989 he was awarded the

**Dirac Medal**and

**Prize of the British Institute of Physics.**In 1990 Penrose was awarded the

**Albert Einstein Medal**for outstanding work related to the work of Albert Einstein by the Albert Einstein Society. In 1991, he was awarded the

**Naylor Prize of the London Mathematical Society.**From 1992 to 1995 he served as

**President of the International Society on General Relativity and Gravitation**. In 1994, Penrose was

**knighted**for services to science. In 1998, he was elected

**Foreign Associate of the United States National Academy of Sciences**. In 2000 he was appointed to the

**Order of Merit**. In 2004 he was awarded the

**De Morgan Medal**for his wide and original contributions to mathematical physics.

*His deep work on General Relativity has been a major factor in our understanding of black holes. His development of Twistor Theory has produced a beautiful and productive approach to the classical equations of mathematical physics. His tilings of the plane underlie the newly discovered quasi-crystals.*

**honorary doctorate**(Honoris Causa) by

**Warsaw University and Katholieke Universiteit Leuven (Belgium**), and in 2006 by the

**University of York**. In 2008 Penrose was awarded the

**Copley Medal**. He is also a

**Distinguished Supporter of the British Humanist Association**.”

**From his wikipedia entry:**

**”Jonathan Penrose**, OBE(born 7 October 1933, in Colchester) is an English chess player, emeritus Grandmaster, and International Correspondence Chess Grandmaster (1983) who won the British Chess Championship ten times between 1958 and 1969. He is the son of Lionel Penrose, a world famous professor of genetics, and brother of Roger Penrose and Oliver Penrose. He is a psychologist and university lecturer by profession.”
