About Milltown Boro, NJ

Milltown was incorporated as a borough by an act of the New Jersey Legislature on January 29, 1889, from portions of North Brunswick, based on the results of a referendum held three days earlier. The borough was reincorporated by resolution of the borough council on May 2, 1896. A portion of East Brunswick Township was annexed in 1902. Originally known as Bergen's Mill, named for Jacob I. Bergen who owned the grist mill, the name is believed to have become "Milltown" from residents "going to the mill in town".

The groundbreaking anxiolytic and sedative drug Miltown (meprobamate) developed by Carter Products, which became available to the public in the mid-1950s, was named for the borough.

Long before the arrival of the first Europeans, the Lenape Native Americans had established settlements along the Lawrence Brook. The discovery of many artifacts in the area above today's municipal building (now a small county park) suggests the presence of a Native American settlement. In 1678, Thomas Lawrence, a New York baker, acquired a large area around the Lawrence Brook, which likely included today's Milltown. The Lawrence Brook was then called Piscopeek (and on later maps, Lawrence's Brook). The names and marks of several Native Americans (Quemareck, Quesiacs, Isarick, Metapis, Peckawan and Turantaca) appear on the bill of sale. In 1769, Fulcard Van Nordstrand advertised the sale of a large gristmill on the bank of Lawrence Brook. It would soon be called Lawrence Brook Mill. The 1903 classic western film The Great Train Robbery was shot in Milltown.

In March 2010, the Milltown City Council voted against changing the name of Petain Avenue, citing the difficulties that the street's residents would endure if the name changed. Petain Avenue is named for Philippe Pétain, a French World War I general who became the leader of the Vichy France government during World War II. The Vichy Regime willfully collaborated with Nazi Germany, taking state action against "undesirables", including Jews, Protestants, gays, gypsies, and left-wing activists. In total, the Vichy government participated in the deportation of 76,000 Jews to German extermination camps, although this number varies depending on the account; only 2,500 survived the war.[31] After the war, Petain was charged with perjury and sentenced to death, though this was commuted to life imprisonment due to his advanced age. France has since changed the name of every street formerly known as Petain.
