## History

The area that is now Interlaken was purchased in 1667 by Gavin Drummond from the Lenape Native Americans. It was later part of Ocean Township, which had seceded from Shrewsbury Township in 1849 and included at the time present-day Eatontown, Neptune Township, Neptune City, Avon-by-the-Sea, Bradley Beach, Asbury Park, Allenhurst, Deal, Long Branch, West Long Branch, Loch Arbour, Monmouth Beach, Sea Bright, and Oceanport, along with Interlaken itself.
Dr. Francis Weld, a Boston physician, bought a 364-acre (1.47 km$^2$) tract and named it Interlaken Farm, after Interlaken, a peninsula in Switzerland situated between two lakes, that they had just visited, which was similar to the borough's location between two sections of Deal Lake. Weld established the Interlaken Land Company in 1890 to turn his farm into a residential community with avenues named after English lakes and cross streets named after the islands in the Hebrides in the Irish Sea. While the initial effort did not succeed, the Stormfelz-Lovely-Neville Company was hired in 1905 to continue the building project, and the community began its growth.
Interlaken was formed as a borough on March 11, 1922, based on the results of a referendum held on May 3, 1922. The first mayor and council of Interlaken were seated on June 26, 1922.
Interlaken remains entirely residential, as was originally intended by its developers. The borough had been the only municipality in the state without any businesses, until a day-care center opened in 1992 under the terms of a state law that required approval of child care establishments serving five children or fewer.
