John Hipple Mitchell, also known as John Mitchell Hipple, John H. Mitchell, or J. H. Mitchell (June 22, 1835December 8, 1905) was an American lawyer, politician, and convicted criminal. He served as a Republican United States Senator from Oregon on three occasions between 1873 and 1905. He also served as president of the state senate, did the initial legal work involved in the dispute that led to the landmark Supreme Court case of Pennoyer v. Neff, and later was involved with the Oregon land fraud scandal, for which he was indicted and convicted while a sitting U.S. Senator. He is one of twelve U.S. Senators indicted while in office, and one of five convicted. Early life He was born in Washington County, Pennsylvania, with the name John Mitchell Hipple. He moved with his parents to Butler County, Pennsylvania, at the age of two. He attended public schools during much of his childhood, but also attended some private schools including the Witherspoon Institute. As a young man he was a schoolteacher. He seduced a 15-year-old female student, and, due to the resulting scandal, was forced to marry her. Legal career In 1857, Mitchell stopped teaching and decided to become a lawyer. He built a successful law practice in Pennsylvania. However, in 1860, he decided to leave his community and family, and moved to California with a local schoolteacher with whom he was having an affair. After arriving in California, he abandoned her and moved to Portland, Oregon. It was then that he decided to change his name to John Hipple Mitchell, using his middle name as his last name, and attempted to start a completely new life in Oregon. Almost immediately, he started to become a successful lawyer and build political connections. Mitchell was not an intellectual man, but he was very ambitious and knew how to develop business and political friendships with important people. In 1867, he was hired as a professor at Willamette University School of Medicine to teach medical jurisprudence. Mitchell remained as professor for almost four years. During his law practice in Oregon, Mitchell did some legal work for a client named Marcus Neff. Mitchell's dispute with Neff regarding some unpaid legal bills gave rise to the circumstances that led to the U.S. Supreme Court case of Pennoyer v. Neff. Political career Two years after arriving in Oregon, in 1862, he was elected to the Oregon State
