Solon Wesley Pierce (March 7, 1831 – September 23, 1903) was an American politician, author, attorney, and newspaper publisher/editor.
Pierce was born in Yorkshire (Cattaraugus County), New York in 1831, studied at the Mendon Academy in Monroe County, NY and settled in Adams County, Wisconsin in 1854, taking up practice as a lawyer in the county seat of Friendship when he was admitted to the bar in 1858. He was first elected district attorney of Adams County in 1861, and the same year (with several associates) founded the Adams County Press, just a few weeks after the outbreak of the US Civil War. Pierce remained as editor and publisher of this newspaper (one of the first published in Adams County) for the majority of the next 40 years until his death in 1903.
In 1864 Pierce enlisted in the Union army, was commissioned a First Lieutenant, and saw action (with the regiments that made up the 9th Army Corps, Army of the Potomac) at the Siege of Petersburg, among other battles toward the end of the Civil War. These experiences formed the basis of his 1866 book Battle Fields and Camp Fires of the 38th Regiment, published by the Daily Wisconsin Printing House of Milwaukee. After his honorable discharge in 1865, Pierce resumed his law practice and newspaper duties, serving several years as county judge, and beginning in 1870 was elected as a legislator to the Wisconsin Assembly, being re-elected to the same body in 1877, 1878, 1880, 1881, 1882, and 1897. He served as chairman of the Assembly's judiciary committee in 1880, 1881, and 1882. As Adams County district attorney in 1892, he instituted the first successful gerrymander suit in the state of Wisconsin. He is also credited with being the author of an 1882 amendment to the Wisconsin state constitution which provided for biennial elections of legislators.
Pierce died at his home in Friendship, Wisconsin.
