The name of the variation refers to Augustus J. Jaeger, who was employed as 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" being German for hunter.
