Bayard Taylor Hainer (1860–1933) was a justice of the Territorial Oklahoma Supreme Court in 1898.
Bayard Taylor Hainer was born in Columbia, Missouri on May 31, 1860. His father was Ignace Hainer and his mother was Adelaide (Barthos) Hainer. Bayard's family moved to Iowa when the Civil War broke out.[1] Bayard earned a B. S. from Iowa State College in 1884 (no major identified), and a Bachelor of Laws from University of Michigan in 1887. Admitted to the bar in Michigan in the same year, he moved to Larned, Kansas to start practicing law.[1]
Settling in Guthrie, immediately after the Land Run of 1889, Hainer was appointed as Guthrie's city councillor, a position he held until 1898. In that year, the President of the United States appointed him as a justice of the Oklahoma Territory Supreme Court on February 16, 1898, succeeding Judge Bierer.[2]
He was a lawyer, journalist and author, as well as active in Republican Party politics. On October 6, 1891, he married Florence Weatherby, who was the daughter of Mrs. Mary Weatherby of Des Moines, Iowa.
