Jack Mills, born Jacob Minsky, (5 December 1891 - 23 March 1979) was a Russian-born American music publisher and songwriter.
He ultimately became manager of the McCarthy & Fisher music publishing house prior to establishing his own company.
The company was noted for its many ragtime and jazz publications during the 1920s and 1930s, and for its relationship with the African-American music community during that period.
[4] Jacob immigrated with his family to the United States at the age of five at which point his parents Americanized his first name to Jack.
[2][3] After finishing the eighth grade, Jack Mills left school and began working for a department store[2] where he was principally responsible for selling neck ties.
[2] Soon after he founded the company Jack was joined in this enterprise by his younger brother Irving Mills.
[4] An important early song by a black composer published by the company was the rag "Kitten of the Keys" (1921) by Zez Confrey.
