Vaudeville star, international recording artist, and composer (born September 1, 1886 in Salto Canavese, Torino, Piemonte, Italy – died July 26, 1950 Loma Linda, San Bernardino County, California, United States).

Guido Deiro was the first piano-accordionist to appear on big-time vaudeville, records, radio, and the screen. In October 1909, he emigrated to the United States, following his younger brother and fellow accordionist, Pietro Deiro, who had gone to America two years earlier. After several successful engagements in Seattle, San Francisco, and elsewhere on the West Coast, Deiro went to New York. There, he recorded around 100 titles for Columbia between 1911 and 1924.

Between 1914-1920, Deiro was married to Mae West. Between 1914 and 1915, they went on the Vaudeville circuit together, but in 1916, she left him.
