English National Opera

In November 1937, Baylis died of a heart attack. Her three companies continued under the direction of her appointed successors: Tyrone Guthrie at the Old Vic, in overall charge of both theatres, with de Valois running the ballet, and Carey and two colleagues running the opera. In the Second World War, the government requisitioned Sadler's Wells as a refuge for those made homeless by air-raids. Guthrie decided to keep the opera going as a small touring ensemble of 20 performers. Between 1942 and the war's end in 1945, the company toured continuously, visiting 87 venues. Joan Cross led and managed the company, and also sang leading soprano roles in its productions when needed. The size of the company was increased to 50, and then to 80. By 1945, its members included singers from a new generation such as Peter Pears and Owen Brannigan, and the conductor Reginald Goodall.

Sadler's Wells Opera

Both Sadler's Wells and the Royal Opera House had presented no opera or ballet since 1939. The Council for the Encouragement of Music and the Arts (CEMA), the official government body charged with dispensing the modest public subsidy recently introduced, considered its options on the future of opera in Britain. CEMA concluded that a new Covent Garden company should be established, as a year-round, permanent ensemble, singing in English, instead of the shorter international seasons of pre-war years. This was a potential path to merge the two companies, as the modus operandi of the new Covent Garden company was now similar to that of Sadler's Wells. However, David Webster, who was appointed to run Covent Garden, though keen to secure de Valois' ballet company for Covent Garden, did not want the Sadler's Wells opera company. He considered Sadler's Wells to be a worthy organisation, but also "dowdy" and "stodgy". Even with a policy of singing in English, he believed that he could assemble a better company. The management of Sadler's Wells was unwilling to lose its company's name and tradition. It was agreed that the two companies should remain separate.

Divisions within the company threatened its continued existence. Cross announced her intention to re-open Sadler's Wells theatre with Peter Grimes by Benjamin Britten, with herself and Pears in the leading roles. Many complaints resulted about supposed favouritism and the "cacophony" of Britten's score. Peter Grimes opened in June 1945, to both public and critical acclaim; its box-office takings matched or exceeded those for La bohème and Madame Butterfly, which the company was concurrently staging. However, the rift within the company was irreparable. Cross, Britten and Pears severed their ties with Sadler's Wells in December 1945 and founded the English Opera Group. The departure of the ballet company to Covent Garden two months later deprived Sadler's Wells of an important source of income, as the ballet had been profitable and had since its inception subsidised the opera company.

Clive Carey, who had been in Australia during the war, was brought back to replace Joan Cross and rebuild the company. The critic Philip Hope-Wallace wrote in 1946 that Carey had begun to make a difference, but that Sadler's Wells needed "a big heave to get out of mediocrity". In the same year, The Times Literary Supplement asked whether the Old Vic and Sadler's Wells companies would stick to their old bases, "or shall they boldly embrace the ideal of a National Theatre and a National Opera in English?" Carey left in 1947, replaced in January 1948 by a triumvirate of James Robertson as musical director, Michael Mudie as his assistant conductor and Norman Tucker in charge of administration. From October 1948, Tucker was given sole control. Mudie became ill, and the young Charles Mackerras was appointed to deputise for him.

By 1950 Sadler's Wells was receiving a public subsidy of £40,000 a year, whilst Covent Garden received £145,000. Tucker had to give up the option of staging the premiere of Britten's Billy Budd, for lack of resources. Keen to improve the dramatic aspects of opera production, Tucker engaged eminent theatrical directors including Michel Saint-Denis, George Devine and Glen Byam Shaw worked on Sadler's Wells productions in the 1950s. New repertoire was explored, such as the first British staging of Janáček's Káťa Kabanová, at Mackerras's urging. Standards and company morale were improving. The Manchester Guardian summed up the 1950–51 London opera season as "Excitement at Sadler's Wells: Lack of Distinction at Covent Garden" and judged Sadler's Wells to have moved "into the front rank of opera houses".

The company continued to leave Rosebery Avenue for summer tours to British cities and towns. The Arts Council (successor to CEMA) was sensitive to the charge that since 1945, far fewer opera performances had been given in the provinces. The small Carl Rosa Opera Company toured constantly, but the Covent Garden company visited only those few cities with theatres big enough to accommodate it. In the mid-1950s, renewed calls appeared for a reorganisation of Britain's opera companies. There were proposals for a new home for Sadler's Wells on the South Bank of the Thames near the Royal Festival Hall, which fell through because the government was unwilling to fund the building.

Once again, there was serious talk of merging Covent Garden and Sadler's Wells. The Sadler's Wells board countered by proposing a closer working arrangement with Carl Rosa. When it became clear that this would require the Sadler's Wells company to tour for 30 weeks every year, effectively removing its presence on the London opera scene, Tucker, his deputy Stephen Arlen, and his musical director Alexander Gibson resigned. The proposals were modified, and the three withdrew their resignations. In 1960, the Carl Rosa Company was dissolved. Sadler's Wells took over some of its members and many of its touring dates, setting up "two interchangeable companies of equal standing", one of which played at Sadler's Wells theatre while the other was on the road.

By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, with Margaret Gale in the title role, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended. The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.

The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available. Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968. One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968.

Coliseum

The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.

The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai. The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.

The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".

A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".

Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.

1980–99

In 1982, at Elder's instigation, Harewood appointed David Pountney director of productions. In 1985 Harewood retired, becoming chairman of ENO's board the following year. Peter Jonas succeeded Harewood as managing director. The 1980s leadership team of Elder, Pountney and Jonas became known as the "Powerhouse", initiated a new era of "director's opera". The three of them favoured productions described, contrastingly, by Elder as "groundbreaking, risky, probing and theatrically effective", and by the director Nicholas Hytner as "Euro-bollocks that never has to be comprehensible to anybody but the people sitting out there conceiving." Directors who did not, in Harewood's phrase, "want to splash paint in the face of the public" were sidelined. A 1980s audience survey showed that the two things that ENO audiences most disliked were poor diction and the extremes of "director's opera".

In the Grove Dictionary of Music and Musicians, Barry Millington has described the 'Powerhouse' style as "arresting images of dislocated reality, an inexhaustible repertory of stage contrivances, a determination to explore the social and psychological issues latent in the works, and above all an abundant sense of theatricality." As examples, Millington mentioned Rusalka (1983), with its Edwardian nursery setting and Freudian undertones, and Hansel and Gretel (1987), its dream pantomime peopled by fantasy figures from the children's imagination... Lady Macbeth of the Mtsensk District (1987) and Wozzeck (1990) exemplified an approach to production in which grotesque caricature jostles with forceful emotional engagement.

Poor average box-office sales led to a financial crisis, exacerbated by backstage industrial relations problems. After 1983, the company ceased touring to other British venues. Assessing the achievements of the 'Powerhouse' years, Tom Sutcliffe wrote in The Musical Times:

ENO is not second best to Covent Garden. It is different, more theatrical, less vocal.... The ENO now follows a policy like Covent Garden's in the early years after the war, when Peter Brook was scandalising the bourgeoisie with his opera stagings. The last two seasons at the ENO have been difficult, or at any rate sentiment has turned against the outgoing regime over the last nine months. Audience figures are well down.... The presiding genius of the Elder years has, of course, been David Pountney. Not because his productions were all marvellous. Perhaps only a few were. But because, like Elder, he enabled so many other talents to thrive.

Productions during the 1980s included the company's first presentations of Pelléas and Mélisande (1981), Parsifal (1986) and Billy Budd (1988). 1980s productions that remained in the repertory for many years included Xerxes directed by Hytner, and Rigoletto and The Mikado directed by Jonathan Miller. In 1984 ENO toured the United States; the travelling company, led by Elder, consisted of 360 people; they performed Gloriana, War and Peace, The Turn of the Screw, Rigoletto and Patience. This was the first British company to be invited to appear at the Metropolitan Opera in New York, where Patience received a standing ovation and Miller's production of Rigoletto, depicting the characters as mafiosi, was greeted with a mixture of enthusiasm and booing. In 1990 ENO was the first major foreign opera company to tour the Soviet Union, performing the Miller production of The Turn of the Screw, Pountney's production of Macbeth, and Hytner's much-revived Xerxes.
