Sir Edward William Elgar, 1st Baronet, OM, GCVO (1857 – 1934) was an English composer, many of whose works have entered the British and international classical concert repertoire. Among his best-known compositions are orchestral works including the Enigma Variations, the Pomp and Circumstance Marches, concertos for violin and cello, and two symphonies. He also composed choral works, including The Dream of Gerontius, chamber music and songs. He was appointed Master of the King's Musick in 1924. He composed his Variations on an Original Theme, Op. 36, popularly known as the Enigma Variations, between October 1898 and February 1899. It is an orchestral work comprising fourteen variations on an original theme.

Elgar dedicated the work "to my friends pictured within", each variation being a musical sketch of one of his circle of close acquaintances (see musical cryptogram). Those portrayed include Elgar's wife Alice, his friend and publisher Augustus J. Jaeger and Elgar himself. In a programme note for a performance in 1911 Elgar wrote: "This work, commenced in a spirit of humour & continued in deep seriousness, contains sketches of the composer's friends. It may be understood that these personages comment or reflect on the original theme & each one attempts a solution of the Enigma, for so the theme is called. The sketches are not 'portraits' but each variation contains a distinct idea founded on some particular personality or perhaps on some incident known only to two people. This is the basis of the composition, but the work may be listened to as a 'piece of music' apart from any extraneous consideration." In naming his theme "Enigma", Elgar posed a challenge which has generated much speculation but has never been conclusively answered. The Enigma is widely believed to involve a hidden melody.

Variation IX (Adagio) "Nimrod": The name of the variation refers to Augustus J. Jaeger, who was employed as a music editor by the London publisher Novello & Co. He was a close friend of Elgar's, giving him useful advice but also severe criticism, something Elgar greatly appreciated. Elgar later related how Jaeger had encouraged him as an artist and had stimulated him to continue composing despite setbacks. Nimrod is described in the Old Testament as "a mighty hunter before the Lord", Jäger (which can also be spelt Jaeger) being German for hunter.
