Howard Zebulun Plummer (16 November 1899 in Philadelphia, Pennsylvania - 24 February 1980) was a Black Hebrew Israelite religious leader.
His father joined the Church of God and Saints of Christ soon after Howard’s birth, and the Plummer family became intimately involved in its doctrine and work.
In August, 1900, in the city of Philadelphia Howard's parents brought him to be blessed by the Church’s founder, prophet William Saunders Crowdy.
After the death of Bishop Plummer on December 22, 1931, at a meeting of Church Officials held December 28, 1931, in Belleville, Elder Calvin S. Skinner consecrated Elder Howard Z. Plummer and proclaimed him as Leader of the Church of God and Saints of Christ.
Rabbi Plummer's religious life embraced contact with many of the country's leading ministers and educators and collaboration with them in numerous activities.
