Michael Bernard Bloomfield (July 28, 1943 - February 15, 1981) was an American guitarist and composer, born in Chicago, Illinois, who became one of the first popular music superstars of the 1960s to earn his reputation almost entirely on his instrumental prowess, since he rarely sang before 1969. Respected for his guitar playing, Bloomfield knew and played with many of Chicago's blues legends before achieving his own fame and was instrumental in popularizing blues music in the mid-1960s. He was ranked number 22 on Rolling Stone's list of "100 Greatest Guitarists of All Time" in 2003 and number 42 by the same magazine in 2011. He was inducted into the Blues Hall of Fame in 2012 and, as a member of the Paul Butterfield Blues Band, was inducted into the Rock and Roll Hall of Fame in 2015.

Bloomfield was born into a wealthy Chicago Jewish-American family. Bloomfield's father, Harold Bloomfield, was born in Chicago in 1914. After pursuing business ventures in California during the 1920s, he returned to the city in the early 1930s. Harold Bloomfield began manufacturing restaurant supplies, and by the latter part of the decade his company, Bloomfield Industries, was making pie cases, kitchen utensils, salt and pepper shakers, and sugar pourers. By the early 1940s Bloomfield Industries had acquired more manufacturing and warehouse space. The company expanded during World War II by manufacturing supplies needed for the war effort. Working with his brother, Daniel, and his father, Samuel, Harold Bloomfield built up Bloomfield Industries into a thriving business. Michael Bloomfield's mother was born Dorothy Klein in Chicago in 1918 and married Harold Bloomfield in 1940. She came from an artistic, musical family, and worked as an actor and a model before marrying Bloomfield. Michael Bloomfield's brother Allen Bloomfield was born in Chicago on Dec. 24, 1944.  Bloomfield's family lived in various locations around Chicago before settling at 424 West Melrose Street on the North Side. When he was twelve his family moved to suburban Glencoe, Illinois, where he attended New Trier High School for two years. During this time, he began playing in local bands, and Bloomfield put together a group called the Hurricanes, named after Ohio rock band Johnny and the Hurricanes. New Trier High School expelled Bloomfield after his band performed a raucous rock and roll song at a 1959 school gathering. He attended Cornwall Academy in Massachusetts for one year and then returned to Chicago, where he spent his last year of education at a local YMCA school, Central YMCA High School.  Bloomfield had attended a 1957 Chicago performance by blues singer Josh White, and began spending time in Chicago's South Side blues clubs and playing guitar with such black bluesmen as Sleepy John Estes, Yank Rachell, and Little Brother Montgomery. He first sat in with a black blues band in 1959, when he performed with Luther "Guitar Junior" Johnson at a Chicago club called the Place. He performed with Howlin' Wolf, Muddy Waters, and many other Chicago blues performers during the early 1960s.  Writing in 2001, keyboardist, songwriter and record producer Al Kooper said Bloomfield's talent "was instantly obvious to his mentors. They knew this was not just another white boy; this was someone who truly understood what the blues were all about." Among his early supporters were B.B. King, Muddy Waters, Bob Dylan and Buddy Guy. "Michael used to say, 'It's a natural. Black people suffer externally in this country. Jewish people suffer internally. The suffering's the mutual fulcrum for the blues.'"
