Yes, the dog in the painting that spawned one of the most iconic commercial logos in history, really does have a name. Nipper.

He was a mongrel (part Jack Russell Terrier) from Bristol, England and ended up being the model for painter Francis Barraud's work, "His Master's Voice." The image of the dog looking into the gramophone, was turned into a logo that became synonymous with music and sound equipment companies such as EMI, RCA, RCA Victor and Bluebird among others.

Nipper was born in 1884 and received his name because he would nip at people's legs.

Nipper originally lived with his owner, Mark Henry Barraud, in the Prince's Theatre where Barraud was a scenery designer. When Barraud died in 1887, his brothers Philip and Francis took care of the dog. Nipper himself died of natural causes in 1895 and was buried in Kingston upon Thames in Clarence Street, in a small park surrounded by magnolia trees. As time progressed the area was built upon, and a branch of Lloyds Bank now occupies the site. On the wall of the bank, just inside the entrance, a brass plaque commemorates the terrier that lies beneath the building.

On 10 March 2010, a small road near to the dog's resting place in Kingston upon Thames was named Nipper Alley in commemoration of this resident.
