Larimer was originally settled by Germans in the later half of the 19th century. By the early 1900s Italians from Abruzzi, Calabria, Campania, Sicily and Northern Italians became the dominant ethnic group. These settlers were slightly better-off than their kinsmen who moved to Bloomfield around the same time: the residents of Bloomfield built modest frame row-houses, while those in Larimer built somewhat nicer detached brick homes with small yards. Before long, Larimer residents had built and were running concrete foundries and commercial bakeries along Lincoln Avenue towards Two-Mile Run (some of which still exist today), and a successful commercial district at the intersection of Larimer Avenue and Meadow Street, near the community's spiritual home of Our Lady Help of Christians Catholic Church (1898). In 1928, the Italian Sons and Daughters of America was founded in the neighborhood. Larimer was Pittsburgh's Little Italy until the 1960s.
