Graham returned to teaching in Kenosha, but soon was called to higher office. He was appointed to the
University of Wisconsin Board of Regents in 1868, where he played a consequential role in shaping state schools. Graham's next project came in 1871, when a new Normal School was established at Oshkosh (now the
University of Wisconsin–Oshkosh). The school's president, George S. Albee, called on Graham and Graham would go on to serve as Professor at the Normal School for the next ten years. He was a candidate for
State Superintendent of Public Instruction in 1873 and 1875, but was not elected. In 1881, however, he was nominated by consensus of the Republican, Democratic, and Prohibition parties, winning an overwhelming majority. He was re-elected in 1884, running on the Republican ticket. He left office in 1887 and returned to teaching. He died on December 14, 1892, at Oshkosh. After a funeral, his body was sent to New York to be interred at his family's burial plot. ==Personal life and family==
