John Rogers Thomas (26 March 1830 - 5 April 1896) was an American composer, pianist, and singer of Welsh descent.
Thomas was born in Newport, Rhode Island. A baritone and composer, he first came to America with the Sequin English Opera Company and became interested in the music of America that was developing. He sang and toured with Bryant's Minstrels and settled in New York.
He wrote more than one hundred popular American songs during the nineteenth century of which his most popular were The Cottage by the Sea (1856), Old Friends and Old Times (1856), Bonny Eloise—The Belle of Mohawk Vale (1858), 'Tis But a Little Faded Flower (1860), When the War Is Over, Mary (1864), Beautiful Isle of the Sea (1865), Croquet (1867), Eilleen Allanna (1873), and Rose of Killarney (1876). Thomas occasionally published material under the pseudonyms Charles Osborne, Arthur Percy and Harry Diamond. In addition to song writing, Thomas composed three larger works; The Picnic (1869), a children's operetta with a libretto by George Cooper; The Lady in the Mask (1870), an operetta with a libretto by George Cooper; and Diamond Cut Diamond (1876), a parlor opera in one act.[1]
