Handel was born in Halle (which was then in the Duchy of Magdeburg, a province of Brandenburg-Prussia) to Georg and Dorothea (née Taust) Händel in 1685,:. His father, Georg Händel, 63 when his son was born, was an eminent barber-surgeon who also served as surgeon to the court of Saxe-Weissenfels and the Margraviate of Brandenburg. According to John Mainwaring, his first biographer, "Handel had discovered such a strong propensity to Music, that his father who always intended him for the study of the Civil Law, had reason to be alarmed. He strictly forbade him to meddle with any musical instrument but Handel found means to get a little clavichord privately convey'd to a room at the top of the house. To this room he constantly stole when the family was asleep". At an early age Handel became a skillful performer on the harpsichord and pipe organ.:[3–4] One day Handel and his father went on a trip to Weissenfels to visit either his son (Handel's half-brother) Carl, or grandson (Handel's nephew) Georg Christian, who was serving as a valet to Duke Johann Adolf I. According to legend, the young Handel attracted the attention of the Duke with his playing on the church organ. At his urging, Handel's father permitted him to take lessons in musical composition and keyboard technique from Friedrich Wilhelm Zachow, the organist of the Lutheran Marienkirche. From then on Handel learned about harmony and contemporary styles, analysed sheet music scores, learned to work fugue subjects and copy music. Sometimes he would take his teacher's place as organist for services.: In 1698 Handel played for Frederick I of Prussia and met Giovanni Battista Bononcini in Berlin, in 1701 Georg Philipp Telemann went to Halle to listen to the promising young man.
From Halle to Italy
The Hamburg Opera am Gänsemarkt in 1726
In 1702, following his father's wishes, Handel started studying law at the University of Halle;:[17–18] and also succeeded in getting an appointment as the organist at the local Protestant cathedral. After a year Handel seems to have been very unsatisfied and in 1703, he moved to Hamburg, accepting a position as violinist and harpsichordist in the orchestra of the opera house.: There he met Johann Mattheson, Christoph Graupner and Reinhard Keiser. His first two operas, Almira and Nero, were produced in 1705.: He produced two other operas, Daphne and Florindo, in 1708. It is unclear if Handel directed these performances himself in the Oper am Gänsemarkt.
According to Mainwaring, in 1706 Handel travelled to Italy at the invitation of Ferdinando de' Medici, but Mainwaring must have been confused. It was Gian Gastone de' Medici, whom Handel had met in 1703/1704 in Hamburg. Ferdinando, who had succeeded in making Florence the musical capital of Italy, attracting the leading talents of his day, had a keen interest in opera. There Handel met the librettistAntonio Salvi, with whom he would collaborate. According to rumours at the time, he also had a love affair with Vittoria Tarquini, a singer. Handel left for Rome and, as opera was (temporarily) banned in the Papal States, composed sacred music for the Roman clergy; the famous Dixit Dominus (1707) is from this era.:[24, 26] He also composed many cantatas in pastoral style for musical gatherings in the palace of Cardinals Pietro Ottoboni, Benedetto Pamphili and Carlo Colonna. Two oratorios, La Resurrezione and Il Trionfo del Tempo, were produced in a private setting for Ruspoli and Ottoboni in 1709 and 1710, respectively. Rodrigo, his first immature, but all-Italian opera, was produced in the Cocomero theatre in Florence in 1707.:[29–30]Agrippina was first produced in 1709 at Teatro San Giovanni Grisostomo, the prettiest theatre at Venice, owned by the Grimani's. The opera, with a libretto by cardinal Vincenzo Grimani, ran for an unprecedented 27 performances. It showed remarkable maturity and established Handel's reputation as a composer of opera. The audience, thunderstruck with the grandeur and sublimity of his style, applauded for Il caro Sassone.
Handel spent the most carefree time of his life as house composer at Cannons in Middlesex and laid the cornerstone for his future choral compositions in the twelve Chandos Anthems.Romain Rolland stated that these anthems were as important for his oratorios as the cantatas were for his operas. Rolland also highly estimated Acis and Galatea, like Winton Dean, who wrote that "the music catches breath and disturbs the memory". During Handel's lifetime it was his most performed work.
Handel was a canny investor: he put money into South Sea stock in 1716 when prices were low  and had sold up by 1720 when the South Sea credit bubble burst in one of the greatest financial cataclysms in fiscal history.
In 1733 the Earl of Essex received a letter with the following sentence: "Handel became so arbitrary a prince, that the Town murmurs". The board of chief investors expected Handel to retire when his contract ended, but Handel immediately looked for another theatre. In cooperation with John Rich he started his third company at Covent Garden Theatre. Rich was renowed for his spectacular productions: he suggested Handel use his small chorus and introduce the dancing of Marie Sallé, for whom Handel composed Terpsichore. In 1735 he introduced organ concertos between the acts. For the first time Handel allowed Gioacchino Conti, who had no time to learn his part, to substitute arias. Financially, Ariodante was a failure, although he introduced ballet suites at the end of each act.Alcina, his last opera with a magic content, and Alexander's Feast or the Power of Music based on John Dryden's Alexander's Feast starred Anna Maria Strada del Pò and John Beard (tenor).
In April 1737, at age 52, Handel suffered an apparent stroke which left his right arm temporarily paralysed, preventing him from performing.: He also complained of difficulties in focussing his eyesight. In summer the disorder seemed at times to affect his understanding. Nobody expected that Handel would ever be able to perform again. But whether the affliction was rheumatism, a stroke or a nervous breakdown, he recovered remarkably quickly. To aid his recovery, Handel had travelled to Aachen, a spa in Germany. During six weeks he took long hot baths, and ending up playing the organ for a surprised audience.
Handel's first attempt at oratorio was made in Italy in 1707-1708 with the Il Trionfo del Tempo e del Disinganno, an allegory, and La Resurrezione which uses material from the bible. His next attempt was Haman and Mordecai performed at Cannons, in which the anthem character is very clear. Unfortunately the circumstances of Esther and its first performance are obscure. Another twelve years passed when an act of piracy, caused him to take up Ester once again. Three earlier performances aroused such interest that they naturally prompted the idea of introducing it to a larger public. Next came Deborah, also strongly coloured by the anthem and Athaliah, in which Handel laid the foundation for the traditional use of the chorus which marks his later oratorios. Obviously Handel became sure of himself, broader in his presentation, and more diverse in his composition.
It is evident how much he learnt fromn Corelli about writing for instruments, and from Alessandro Scarlatti about writing for the solo voice; but there is no single composer who taught him how to write for chorus. Handel tended more and more to replace Italian soloists by English ones. The weightiest reason for this change was the dwindling financial returns from his operas. Thus a tradition was created for oratorios which was to govern their future performance. The performances were given without costumes and action; the performers appeared in a black suit.
In 1736 Handel came with Alexander's Feast. John Beard appeared for the first time as one of Handel's principal singers and became Handel's permanent tenor soloist for the rest of his life. The piece was a great success and it encouraged Handel to make the transition from writing Italian operas to English choral works. In Saul, Handel was collaborating with Charles Jennens and experimenting with three trombones, a carillon and extra-large military kettledrums (from the Tower of London), to be sure "...it will be most excessive noisy". Saul and Israel in Egypt both from 1739 head the list of great, mature oratorios, in which the da capo and dal segno aria became the exception and not the rule. Israel in Egypt consists of little else but choruses, borrowing from the Funeral Anthem for Queen Caroline. In his next works Handel changed his course. In these works he laid greater stress on the effects of orchestra and soloists; the chorus retired into the background.L'Allegro, il Penseroso ed il Moderato has a rather diverting character; the work is light and fresh.
During the summer of 1741, the 3rd Duke of Devonshire invited Handel to Dublin to give concerts for the benefit of local hospitals.:[40, 41] His Messiah was first performed at the New Music Hall in Fishamble Street, on 13 April 1742, with 26 boys and five men from the combined choirs of St Patrick's and Christ Church cathedrals participating.: Handel secured a balance between soloists and chorus which he never surpassed.
The use of English soloists reached its height at the first performance of Samson. The work is highly theatrical. Jephtha was first performed on 26 February 1752; even though it was his last oratorio, it was no less a masterpiece than his earlier works.:[354–55]

In 1749 he composed Music for the Royal Fireworks; 12,000 people attended the performance.:[297–98] In 1750 Handel arranged a performance of Messiah to benefit the Foundling Hospital. The performance was considered a great success and was followed by annual concerts that continued throughout his life. In recognition of his patronage, Handel was made a governor of the Hospital the day after his initial concert. He bequeathed a copy of Messiah to the institution upon his death.: His involvement with the Foundling Hospital is today commemorated with a permanent exhibition in London's Foundling Museum, which also holds the Gerald Coke Handel Collection. In addition to the Foundling Hospital, Handel also gave to a charity that helped to assist impoverished musicians and their families.
In August 1750, on a journey back from Germany to London, Handel was seriously injured in a carriage accident between The Hague and Haarlem in the Netherlands.: In 1751 his eyesight started to fail in one eye. The cause was a cataract which was operated on by the great charlatan Chevalier Taylor. This led to uveitis and subsequent loss of vision. He died some eight years later in 1759 in London, at the age of 74, with his last attended performance being his own Messiah. More than three thousand mourners attended his funeral, which was given full state honours, and he was buried in Westminster Abbey.:
Handel never married, and kept his personal life private. He left a sizable estate at his death, worth £20,000, the bulk of which he bequeathed to a niece in Germany, with additional gifts to his other relations, servants, friends and favourite charities.

Handel's compositions include 42 operas, 29 oratorios, more than 120 cantatas, trios and duets, numerous arias, chamber music, a large number of ecumenical pieces, odes and serenatas, and 16 organ concerti. His most famous work, the oratorio Messiah with its "Hallelujah" chorus, is among the most popular works in choral music and has become a centrepiece of the Christmas season. Amongst the works with opus numbers published and popularised in his lifetime are the Organ Concertos Op.4 and Op.7, together with the Opus 3 and Opus 6 concerti grossi; the latter incorporate an earlier organ concerto The Cuckoo and the Nightingale in which birdsong is imitated in the upper registers of the organ. Also notable are his sixteen keyboard suites, especially The Harmonious Blacksmith.
Handel's works have been catalogued in the Händel-Werke-Verzeichnis and are commonly referred to by a HWV number. For example, Messiah is catalogued as HWV 56.
After his death, Handel's Italian operas fell into obscurity, except for selections such as the aria from Serse, "Ombra mai fù". Throughout the 19th century and first half of the 20th century, particularly in the Anglophone countries, his reputation rested primarily on his English oratorios, which were customarily performed by enormous choruses of amateur singers on solemn occasions.
Since the 1960s, with the revival of interest in baroque music, original instrument playing styles, and the prevalence of countertenors who could more accurately replicate castrato roles, interest has revived in Handel's Italian operas, and many have been recorded and performed onstage. Since the Early Music Revival the fifty operas he wrote were performed in opera houses and concert halls.
Recent decades have also seen the revival of a number of secular cantatas and what one might call 'secular oratorios' or 'concert operas'. Of the former, Ode for St. Cecilia's Day (1739) (set to texts by John Dryden) and Ode for the Birthday of Queen Anne (1713) are particularly noteworthy. For his secular oratorios, Handel turned to classical mythology for subjects, producing such works as Acis and Galatea (1719), Hercules (1745) and Semele (1744). In terms of musical style, particularly in the vocal writing for the English-language texts, these works have a close kinship with the sacred oratorios, but they also share something of the lyrical and dramatic qualities of Handel's Italian operas. As such, they are sometimes performed onstage by small chamber ensembles. With the rediscovery of his theatrical works, Handel, in addition to his renown as instrumentalist, orchestral writer, and melodist, is now perceived as being one of opera's great musical dramatists.
Handel has generally been accorded high esteem by fellow composers, both in his own time and since. Bach even attempted, unsuccessfully, to meet with Handel while he was visiting Halle.: Mozart is reputed to have said of him, "Handel understands effect better than any of us. When he chooses, he strikes like a thunder bolt." and to Beethoven he was "the master of us all... the greatest composer that ever lived. I would uncover my head and kneel before his tomb". Beethoven emphasised above all the simplicity and popular appeal of Handel's music when he said, "Go to him to learn how to achieve great effects, by such simple means".
After Handel's death, many composers wrote works based on or inspired by his music. The first movement from Louis Spohr's Symphony No. 6, Op. 116, "The Age of Bach and Handel", resembles two melodies from Handel's Messiah. In 1797 Ludwig van Beethoven published the 12 Variations in G major on ‘See the conqu’ring hero comes’ from Judas Maccabaeus by Handel, for cello and piano. Guitar virtuoso Mauro Giuliani composed his Variations on a Theme by Handel, Op. 107 for guitar, based on Handel's Suite No. 5 in E major, HWV 430, for harpsichord. In 1861, using a theme from the second of Handel's harpsichord suites, Johannes Brahms wrote the Variations and Fugue on a Theme by Handel, Op. 24, one of his most successful works (it even received praise from Richard Wagner). Several works by the French composer Félix-Alexandre Guilmant use themes by Handel, for example his March on a Theme by Handel for organ, which uses a theme from Messiah. French composer and flautist Philippe Gaubert wrote his Petite marche for flute and piano based on the fourth movement of Handel's Trio Sonata, Op. 5, No. 2, HWV 397. Argentine composer Luis Gianneo composed his Variations on a Theme by Handel for piano. In 1911, Australian-born composer and pianist Percy Grainger based one of his most famous works on the final movement of Handel's Suite No. 5 in E major (just like Giuliani). He first wrote some variations on the theme, which he titled Variations on Handel's ‘The Harmonious Blacksmith’ . Then he used the first sixteen bars of his set of variations to create Handel in the Strand, one of his most beloved pieces, of which he made several versions (for example, the piano solo version from 1930). Arnold Schoenberg's Concerto for String Quartet and Orchestra in B flat major (1933) was composed after Handel's Concerto Grosso, Op. 6/7.
Handel adopted the spelling "George Frideric Handel" on his naturalisation as a British subject, and this spelling is generally used in English-speaking countries. The original form of his name, Georg Friedrich Händel, is generally used in Germany and elsewhere, but he is known as "Haendel" in France. Another composer with a similar name, Handl, was a Slovene and is more commonly known as Jacobus Gallus.
