Alex or Aleck Miller (né Ford, possibly December 5, 1912 – May 24, 1965), known later in his career as Sonny Boy Williamson, was an American blues harmonica player, singer and songwriter. He was an early and influential blues harp stylist who recorded successfully in the 1950s and 1960s. Miller used various names, including Rice Miller and Little Boy Blue, before calling himself Sonny Boy Williamson, which was also the name of a popular Chicago blues singer and harmonica player. To distinguish the two, Miller has been referred to as Sonny Boy Williamson II.

He first recorded with Elmore James on “Dust My Broom“. Some of his popular songs include “Don’t Start Me Talkin’“, “Help Me“, “Checkin’ Up on My Baby“, and “Bring It On Home“. He toured Europe with the American Folk Blues Festival and recorded with English rock musicians, including the Yardbirds, the Animals, and Jimmy Page. “Help Me” became a blues standard, and many blues and rock artists have recorded his songs.

Miller’s date of birth is disputed. In a spoken word performance called “The Story of Sonny Boy Williamson” that was later included in several compilations, Miller states that he was born in Glendora, Mississippi in 1897. A counter claim is made that he was born Alex Ford (pronounced “Aleck”) on the Sara Jones Plantation in Tallahatchie County, Mississippi. Another claim is that he was born on December 5, 1899. David Evans, professor of music and an ethnomusicologist at the University of Memphis, claims to have found census records that Miller was born around 1912, being seven years old on February 2, 1920, the day of the census. However, it has been argued that a census record claim of age without a birth certificate is not a reliable proof, as census clerks often made mistakes, especially in rural towns where few people could read or write. Miller’s gravestone in or near Tutwiler, Mississippi, set up by record company owner Lillian McMurry twelve years after his death, gives his date of birth as March 11, 1908.
