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 musicians before achieving his own fame and was instrumental in popularizing blues music in the mid-1960s. He was ranked No. 22 on Rolling Stone‘s list of “100 Greatest Guitarists of All Time” in 2003 and No. 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.
