Matthew O. Ricketts was born in Henry County, KY, to enslaved parents. The family moved to Missouri when Ricketts was a small child. He grew up to become the first African American Senator in the Nebraska Legislature in 1892 and was elected again in 1894, serving as an advocate for stronger civil rights laws in Nebraska. He was also a leader of the Prince Hall Masons. 

Ricketts was a graduate of Lincoln Institute in Missouri [now Lincoln University of Missouri] and Omaha Medical College, the first African American to graduate from a college or university in Nebraska.

Ricketts was the husband of Alice Ricketts; the family of four lived in St. Joseph Ward, Buchanan County, MO, according to the 1910 U.S. Federal Census.
