Adolphus Augustus Ellis (5 April 1848 – 25 April 1921) was an American lawyer and politician who served as the 22nd Michigan Attorney General as a member of the Democratic party from 1891 to 1895.
Adolphus Augustus Ellis was born in Vermontville, Michigan on 5 April 1848. In his youth, Ellis would work on his father's farm during the summer season while attending district school in the winter. From 1864 to 1865, he attended Union school in Charlotte. Ellis attempted to enlist into the 5th Michigan Cavalry Regiment in March 1865, but was denied due to his age. Following this, Ellis left for Iowa where he studied for a full year before managing a large farm until his return to Michigan in 1868. Upon his return, Ellis was employed in hardwood lumbering and enrolled at Olivet College in Olivet after acquiring sufficient funds in 1869. He graduated in 1872 and went on to take a teaching job while studying law in his free time. Ellis was admitted to the Michigan bar in January 1876 and practiced law in Muir until 1881. Ellis married Mattie N. Nichols (1849-1931) in 1874 and went on to have two children. The couple moved back to Ionia in 1881.[1]
Adolphus Augustus Ellis was first elected as Prosecuting Attorney for Ionia County in 1884 and re-elected in 1886. Although he had previously served as a delegate to the Chicago labor convention in 1880. He was a candidate for the Greenback Party in the Michigan Attorney General election of 1888, but lost to Republican nominee Stephen V. R. Trowbridge. In the spring of 1890, Ellis was elected Mayor of Ionia, winning re-election the following year. Ellis launched another bid for the office of Michigan Attorney General during the election of 1890, this time on the Democratic ticket. Ellis defeated Republican nominee and incumbent Attorney General Benjamin W. Huston and was re-elected on 8 November 1892 against Republican nominee Gerritt J. Diekema by a margin of 1,322 votes. Upon finishing his term in 1895, Ellis was again elected Mayor of Ionia in 1897 and won re-election in 1898 and 1899.[2]
