The earliest known settlers in Lansdale were members of the Jenkins family. At the peak of its growth, the Jenkins homestead occupied approximately 120 acres of land. The construction of the North Pennsylvania Railroad during the 1850s contributed to rapid growth and expansion in Lansdale. Employment opportunities generated by the railroad brought settlers, housing, and local businesses to the area. By 1872, Lansdale Borough was officially incorporated and named after Phillip Lansdale Fox, chief surveyor of the North Penn Railroad.
