in
Madison, Wisconsin. During his years as a lawyer, Ryan was involved in several notable cases in Wisconsin history. In 1853, he was the prosecutor in the
impeachment of Wisconsin circuit court judge
Levi Hubbell, on charges of corruption. Hubbell was acquitted by the Wisconsin Senate, though, later in life, he would be forced to resign his role as a U.S. Attorney due to similar corruption charges. Ryan was notoriously bad-tempered, and his prosecution of the case against Hubbell was described as viciously personal, and motivated by personal grievances. In 1854 and 1855, Ryan was the attorney for the United States in the case of
Ableman v. Booth, where he prosecuted
abolitionist Sherman Booth for assisting a runaway slave in violation of the
Fugitive Slave Act of 1850. In the Booth case, Ryan was opposed by fellow future-justice,
Byron Paine. Paine prevailed at the Wisconsin Supreme Court, but the decision was later overturned by the
Supreme Court of the United States. Booth would ultimately be pardoned by U.S. President
James Buchanan. ==Family and personal life==
