Al Piantadosi (born John Alberto Joseph Piantadosi) 18 August 1882 New York, New York – 8 April 1955 Encino, California) was an American composer of popular music during the of Tin Pan Alley. He started out as a saloon and vaudeville pianist and rapidly flourished as a songwriter. For about ten years — from 1918 to 1928, he was an independent music publisher.
Piantadosi was born August 18, 1882, in the Italian Quarter of Manhattan, New York. Early in his career ( 1906), Piantadosi gained recognition as "Ragtime Al," playing piano at Callahan's Dance Hall on Manhattan's at Chatham Square and Doyers Street in Chinatown, where he wrote the briefly popular "My Mariucci Take a Steamboat" with lyricist George Ronklyn (1878–1943), the bouncer at Callahan's known as "Big Jerry."
Piantadosi's compositions include "I'm Awfully Glad I'm Irish" (1910) and "That's How I Need You" (1912). "The Curse of an Aching Heart" (1913) became his most famous tearjerker. He also composed "Mississippi Days" (1916) and "If You Had All the World and Its Gold."
His composition, "I Didn't Raise My Boy to Be a Soldier" (1915) became a controversial protest song. It sold 650,000 copies in the first three months, which helped establish American World War I pacifism as a quantifiable political reality. The song continued to sell well until the United States entered the World War I in 1917. Then it was pretty much discarded. However, a few pro-war writers modified the lyrics in new melodies, including "I Didn't Raise My Boy To Be A Coward," by Charles Clinton Case (1843–1918) (composer) and Franklin G. McCauley (lyricist) and "I Didn't Raise My Boy To Be A Slacker," a march by Theodore Baker (1917, G. Schirmer).
