Bloomingdale is a village in DuPage County, Illinois, United States, approximately 25 miles west of Chicago. The population was 22,018 at the 2010 census.
Bloomingdale is one of the earliest villages settled in what is now DuPage County. The Meacham family settled here in 1833, and by the end of the following year, 12 to 15 families had settled in the locality. It was originally named Meacham's Grove.The community was served by the Chicago-Galena Highway, modern day Lake Street. It became an important stop for stage coaches and westward travelers. Originally a Cook Countysettlement, it was annexed by DuPage in 1839, and incorporated as a village later that year. The northern part of the village wanted to develop commercially while the southern part wished to remain a farming community. In 1922, the village split to accommodate this—the northern portion of the town was incorporated as Roselle.
