context_section_description: In January 1871, Wisconsin Supreme Court Justice Byron Paine died unexpectedly.  Governor Lucius Fairchild appointed Judge Lyon to fill the vacancy, and, the following April, his appointment was confirmed in a special election.  Justice Lyon was re-elected in 1877 and 1883.  After the retirement of Chief Justice Orasmus Cole at the end of his 6th term, in 1892, Justice Lyon, as the next most senior Justice, became the Chief Justice of the Wisconsin Supreme Court. Justice Lyon had already announced his intention to retire at the end of his term, however, so only served two years as Chief Justice.
