On the outbreak of the First World War in 1914, Newman, Wood and Speyer discussed whether the Proms should continue as planned. They had by this time become an established institution, and it was agreed to go ahead. However, anti-German feeling forced Speyer to leave the country and seek refuge in the US, and there was a campaign to ban all German music from concerts. Newman put out a statement declaring that German music would be played as planned: "The greatest examples of Music and Art are world possessions and unassailable even by the prejudices and passions of the hour." When Speyer left Britain, the music publishers Chappell's took on the responsibility for the Queen's Hall and its orchestra. The Proms continued throughout the war years, with fewer major new works than before, although there were nevertheless British premieres of pieces by Bartók, Stravinsky and Debussy. An historian of the Proms, Ateş Orga, wrote, "Concerts often had to be re-timed to coincide with the 'All Clear' between air raids. Falling bombs, shrapnel, anti-aircraft fire and the droning of Zeppelins were ever threatening. But kept things on the go and in the end had a very real part to play in boosting morale."
