John Galsworthy first published in 1897 with a collection of short stories entitled "e;The Four Winds"e;. For the next 7 years he published these and all works under his pen name John Sinjohn. It was only upon the death of his father and the publication of "e;The Island Pharisees"e; in 1904 that he published as John Galsworthy. His first play was The Silver Box, an immediate success when it debuted in 1906 and was followed by "e;The Man of Property"e; later that same year and was the first in the Forsyte trilogy. Whilst today he is far more well know as a Nobel Prize winning novelist then he was considered a playwright dealing with social issues and the class system. We publish here 'The Skin Game' a great example of both his writing and his demonstration of how the class system worked at the time. He was appointed to the Order of Merit in 1929, after earlier turning down a knighthood, and awarded the Nobel Prize in 1932 though he was too ill to attend. John Galsworthy died from a brain tumour at his London home, Grove Lodge, Hampstead on January 31st 1933. In accordance with his will he was cremated at Woking with his ashes then being scattered over the South Downs from an aeroplane.

Harriet Elisabeth Beecher Stowe was born in Litchfield, Connecticut, on June 14th 1811. Over the course of her Life Harriet wrote more than twenty books including travel memoirs and collections of letters and articles. Her stand out work is undoubtedly 'Uncle Tom's Cabin' about the life of African Americans under slavery. It reached millions as both a book and a play and was influential in setting both the tone and the agenda for anti slavery forces in the North and for unyielding anger in the South. When she was invited to the White House by Lincoln he is rumoured to have said "e;so you are the little woman who wrote the book that started this great war."e; In the 1870s, Stowe's brother, Henry Ward, also an abolitionist, was accused of adultery and a national scandal ensured. Harriet fled to Florida unable to bear the attacks on her brother, who she believed innocent. Harriet was among the founders of the Hartford Art School, which later became part of the University of Hartford. She was also influential in the call for women to have a better standing in society and considered the cause as just as necessary as the abolition of slavery. With the death of her husband Calvin Stowe in 1886, after a half century together, Harriet's own health started to decline rapidly. By 1888 it was reported in The Washington Post that due to dementia she had started "e;writing Uncle Tom's Cabin over again. She imagined that she was engaged in the original composition, and for several hours every day she industriously inscribed long passages of the book, almost word for word, unconsciously from memory, the authoress imagining that she composed the matter as she went along. To her diseased mind the story was brand new and she frequently exhausted herself with labor which she regarded as freshly created."e; Harriet Beecher Stowe died on July 1, 1896, at age eighty-five in Hartford, Connecticut. She is buried in the historic cemetery at Phillips Academy in Andover, Massachusetts.

Sir William Schwenck Gilbert was born at 17 Southampton Street just off the Strand in London on November 18th 1836. He was a man of a great many talents; dramatist, librettist, poet and illustrator. Of course he is better known as the collaborator with Arthur Sullivan of 14 light comic operas under that world famous moniker Gilbert & Sullivan. They continue to be performed and to entertain millions every year from commercial theatres down to amateur dramatic societies and schools. Here we publish his libretto for The Pirates Of Penzance.

William Shakespeare was born in Stratford-upon-Avon in late April 1565 and baptised there on 26th April. He was one of eight children. Little is known about his life but what is evident is the enormous contribution he has made to world literature. His writing was progressive, magnificent in scope and breathtaking in execution. His plays and sonnets helped enable the English language to speak with a voice unmatched by any other. William Shakespeare died on April 23rd 1616, survived by his wife and two daughters. He was buried two days after his death in the chancel of the Holy Trinity Church. The epitaph on the slab which covers his grave includes the following passage, Good friend, for Jesus's sake forbear, To dig the dust enclosed here. Blessed me the man that spares these stones, And cursed be he that moves my bones. Here we publish his comedy from 1598 'Much Ado About Nothing'.

Henrik Ibsen (20th March, 1828 - 23rd May, 1906) is often referred to as the father of realism and ranked just below Shakespeare as Europe's greatest ever playwright especially as his plays are performed most frequently throughout the world after Shakespeare's. Ibsen was Norwegian and although set his plays in Norway, he wrote them in Danish and lived mot of his professional life in Italy and Germany. His affect on the theatre is still evident today and shapes the distinction of plays being art as opposed to entertainment since he broke down all previous traditions and explored issues, developed characterisation, revealed uncomfortable truths, challenged assumptions and brokedown facades in ourselves as well as society. These factors are clearly demonstrated in the Master Builder which is about Halvard Solness, an incredibly successful builder whose success is due to a lucky series of events which he had conceived and wished for but not actually done anything to make happen. These fortuitous occurrences for him and misfortunes for his competitors makes Solness think that he is divinely blessed to allow him to build churches and that all his wishes will come true. He confides these beliefs to a young woman he originally met as a child and together they fantasise about this magic power. At the same time his wife is uninterested in his buildings but consumed with grief over the loss of her two sons. Solness is ultimately destroyed by this infatuation for the younger woman together with his belief in his own infallibility making this Ibsen work a realistic tragedy with a thought provoking moral to the tale.

Eugene Gladstone O'Neill was born on October 16, 1888 in a hotel bedroom in what is now Times Square, New York. Much of his childhood was spent in the comfort of books at boarding schools whilst his actor father was on the road and his Mother contended with her own demons. He spent only a year at University - Princeton - and various reasons have been given for his departure. However whatever his background and education denied or added to his development it is agreed amongst all that he was a playwright of the first rank and possibly America's greatest. His introduction of realism into American drama was instrumental in its development and paved a path for many talents thereafter. Of course his winning of both the Pulitzer Prize (4 times) and the Nobel Prize are indicative of his status. His more famous and later works do side with the disillusionment and personal tragedy of those on the fringes of society but continue to build upon ideas and structures he incorporated in his early one act plays. Eugene O'Neill suffered from various health problems, mainly depression and alcoholism. In the last decade he also faced a Parkinson's like tremor in his hands which made writing increasingly difficult. But out of such difficulties came plays of the calibre of The Iceman Cometh, Long Day's Journey Into Night, and A Moon for the Misbegotten. Eugene O'Neill died in Room 401 of the Sheraton Hotel on Bay State Road in Boston, on November 27, 1953, at the age of 65. As he was dying, he whispered his last words: "e;I knew it. I knew it. Born in a hotel room and died in a hotel room."e;

William Butler Yeats (1865 - 1939) is best described as Ireland's national poet in addition to being one of the major twentieth-century literary figures of the English tongue. To many literary critics, Yeats represents the 'Romantic poet of modernism,' which is quite revealing about his extraordinary style that combines between the outward emphasis on the expression of emotions and the extensive use of symbolism, imagery and allusions. Yeats also wrote prose and drama and established himself as the spokesman of the Irish cause. His fame was greatly boosted mainly after he received the Nobel Prize in Literature in 1923. His life was marked by his many love stories, by his great interest in oriental mysticism and occultism as well as by political engagement since he served as an Irish senator for two terms. Today, although William Butler Yeats's contribution to literary modernism and to Irish nationalism remains incontestable.
