The 1867 advent of the South Side Railroad provided the transportation infrastructure for a new Long Island community conceived by Irish immigrant Thomas Welwood and Prussian immigrant Charles Schleier. Specifically marketed to German immigrants, the city of Breslau was dedicated in 1870. Welwood and Schleier encouraged business and manufacturing growth, providing local employment and economic stability. The gentlemen planned a model community, but their business dealings were not as harmonious and ended in years of litigation. Although thriving, in 1891, the community sought to discard the name Breslau, and residents chose the name Lindenhurst, honoring the proliferation of local linden trees. In the early 20th century, local business prospered, the population blossomed, and the community built by German immigrants strove to demonstrate their American patriotism when the United States joined the war against Germany.
