Lucas Miltiades Miller (September 15, 1824 – December 4, 1902) was a Greek American immigrant, lawyer, Democratic politician, and Wisconsin pioneer.

He was the first Greek American member of the U.S. House of Representatives, and was an instrumental figure in the establishment and development of the city of Oshkosh, Wisconsin.

[1][a] He was found wandering the streets of an abandoned town shortly after fighting had occurred there, and was adopted by American abolitionist Jonathan Peckham Miller, along with three other Greek orphans.

He attended the common schools until age 16, when he had to begin taking care of his foster father's affairs, due to medical incapacitation.

Ultimately, all of Miller's land became part of the city of Oshkosh, with his central homestead making up what is now the Menominee Park Zoo.

[3] He started a law practice in Oshkosh, and operated a general store in partnership with Edward Eastman, a fellow emigrant from Vermont.

During that legislative term, he advocated for allowing the Menominee people to remain in Wisconsin and furthered his plans for Fox River improvements.

Also during that term, Miller was appointed by the governor to serve as chairman of the state board of commissioners for public works.

[19][20] A few days later, Miller telegraphed from Vermont that he would accept the nomination, but did not cut his vacation short to begin campaigning.

[22] Nevertheless, Miller's campaign was boosted by the political atmosphere in the state, which had turned decisively against the Republicans due to the recently-passed Bennett Law.

The law had outraged Wisconsin's large immigrant community, and subsequent comments by the governor exacerbated that concern and inflamed Catholic passions as well.

[23] After winning the election, there was a brief attempt to question Miller's citizenship status, but he produced papers verifying his naturalization and was allowed to serve in the 52nd Congress.

[25] His most noteworthy action in Congress, was a proposed constitutional amendment[26] to change the country's name to "the United States of the Earth".

"[27][28] In the reapportionment after the 1890 United States census, Wisconsin obtained an additional congressional seat, and a redistricting was undertaken.

Miller's district was substantially changed, removing Outagamie, Adams, and Columbia counties, and adding Manitowoc, Calumet, and Fond du Lac.

Miller attempted to seek re-election in the new district, but faced strong opposition from local Democratic leadership, who sought to replace him with George White Pratt.
