Leonard Garfield Spencer (February 12, 1867 – December 15, 1914) was an early American recording artist. He began recording for the Columbia Phonograph Company, in 1889 or 1890. Between 1892 and 1897 he recorded extensively for the New Jersey Phonograph Company and its successor the United States Phonograph Company. He specialized in vaudeville sketches and comic songs, but also sang sentimental ballads popular at the time. He returned to Columbia in 1898 for an exclusive contract then began recording for Berliner Gramophone (disc) records in 1899 and continued with Victor and Columbia as discs became the dominant format in the early 1900s.
