The city was named for brothers Joseph and Louis Altheimer, two Pine Bluff merchants. Louis, who was born in Eberstadt in 1850, read stories by German adventurer Frederick Gerstacker telling of the rich natural resources in Arkansas, and left for America as a teenager, eventually settling in Pine Bluff. Louis brought his brother Joseph with him to the land that would eventually bear their name. Joseph's son, Benjamin, became a successful attorney, establishing the prominent Chicago law firm of Altheimer, Mayer, Woods, and Smith (later known as Altheimer & Gray), and serving twice as president of Chicago's Iroquois Club, the city's oldest Democratic Party political club. Benjamin owned of land in Arkansas. His foundation, the Ben J. Altheimer Foundation, provided scholarships and funding for projects throughout the state and continues today as the Ben J. Altheimer Charitable Foundation, Inc.
