[2] In 1914, at the start of World War I, it was considered less than ideal in England to bear such a Germanic-sounding name as Hindenberg, so the family name was discreetly dropped and he adopted his third name, Cameron, as his professional surname.

Laudatory reviews by George Bernard Shaw and Percy Grainger increased his renown, and led to London engagements from the Royal Philharmonic Society.

[5][8] In 1929 Cameron organized an all-British festival in Harrogate, including the music of Bax, Delius, Henry Balfour Gardiner, Joseph Holbrooke, William Hurlstone and Peter Warlock.

[2] Also in 1929, Cameron auditioned the pianist Moura Lympany, then aged just 12 years old, and immediately organized her concert debut with him at Harrogate, playing Mendelssohn's G minor Piano Concerto.

[5] Cameron played an essential role in the immediate post World War II period at the Henry Wood Promenade Concerts held in the Royal Albert Hall where, with Malcolm Sargent, he was responsible for the bulk of the programming, including the Bach/Brahms evenings.

One notable occasion was on 7 September 1945 when Cameron conducted the first performance in England of Schoenberg's Piano Concerto, with the 23-year-old pianist Kyla Greenbaum as the soloist.
