John Timm portrays Arthur Calvin Mellette, the last governor of the Dakota Territory and first governor of South Dakota. Timm brings Mellette to life during a meeting of the History and Heritage Book Club in Pierre Tuesday at 7:00 p.m., at the Cultural Heritage Center. The program is free. Mellette was appointed territorial governor in the spring of 1889 and was elected governor of South Dakota that fall. He served as governor until 1893. Timm has been performing living history portrayals of Mellette statewide since 1999. He became interested in Mellette when he was a costumed docet at the Pettigrew Home and Museum in Sioux Falls.
