Samuel Lover was an Irish songwriter, composer and novelist, and a portrait painter, chiefly in miniatures. He was the grandfather of Victor Herbert.

Lover was born at No. 60 Grafton Street, Dublin and went to school at Samuel Whyte's at No. 79, which now houses Bewley's Café. By 1830 he was Secretary of the Royal Hibernian Academy and living at No. 9 D'Olier Street. In 1835 he moved to London and began composing music for a series of comic stage works. For some, like the operetta Il Paddy Whack in Italia (1841), he contributed libretto and music, for others just a few songs.

Lover produced many Irish songs, of which several, such as The Angel's Whisper, Molly Bawn, and The Four-leaved Shamrock, gained popularity. He also wrote novels, of which Rory O'Moore (in its first form a ballad), and Handy Andy are best known, and short Irish sketches, which with his songs he combined into a popular entertainment called Irish Nights or Irish Evenings, with which he toured North America in 1846–1848. He joined Charles Dickens in founding Bentley's Magazine.

"When once the itch of literature comes over a man, nothing can cure it but the scratching of a pen." – Samuel Lover

Lover's daughter Fanny was mother to Victor Herbert, a composer remembered for many musicals and operettas premièred on Broadway. As a child he lived with the Lovers in a musical environment after the divorce of his mother.

Lover died on 6 July 1868 in Saint Helier, Jersey. A memorial in St Patrick's Cathedral, Dublin marks his achievements: "Poet, painter, novelist and composer, who, in the exercise of a genius as distinguished in its versatility as in its power, by his pen and pencil illustrated so happily the characteristics of the peasantry of his country that his name will ever be honourably identified with Ireland."
