Born on December 28, 1926 to Reverend Wade Hampton McKinney and Ruth Berry McKinney in Flint, Michigan, Samuel Berry McKinney would become a Baptist minister, author, and civil rights advocate in Seattle, Washington. He served as pastor of Mount Zion Baptist Church, one of the largest and oldest black churches in the Pacific Northwest, from 1958 to 1998 and again from 2005 to 2008.
As a child in Cleveland, Ohio McKinney was shaped by his father who challenged racism, and invited civil rights leaders such as Thurgood Marshall to speak frequently at his church. McKinney attended Morehouse College with the intention of becoming a civil rights lawyer, but changed paths after encountering Morehouse President Benjamin Mays who encouraged him to become a minister. McKinney, a classmate of Martin Luther King, graduated from Morehouse in 1949 and enrolled in New Yorks Colgate Rochester Divinity School, graduating in 1952. One year later he married Louise Jones, an educator and activist in her own right. The couple has two daughters.
McKinney served as pastor of Olney Street Baptist Church in Providence, Rhode Island between 1955 and 1958. He arrived at Mt. Zion in 1958, beginning an activist ministry that transformed the church and Seattle. At Mt. Zion, McKinney established numerous programs that assisted the black community including the Mount Zion Baptist Church Credit Union in 1958, the first Protestant credit union in the state of Washington. McKinney was a founder of Liberty Bank, the first black-owned bank in Seattle and was the first black president of the Church Council of Greater Seattle.
In 1966 McKinney founded and served as president and CEO of the Seattle Opportunity Industrialization Center.

Zion Pre-School and Kindergarten, and the Ethnic School (later the Louise Jones McKinney Learning Center), were founded. In 1975 he earned a Doctor of
