The Ouilmette Reserve
Antoine Ouilmette, a French-Canadian fur trader, was among Chicago’s first residents in 1790. His wife, Archange Chevalier Ouilmette, was Potawatomi, and the 1829 Treaty of Prairie du Chien granted her and her children 1,280 acres along the lake. The family lived in a log cabin near today’s Michigan Shores Club until 1838, and the children sold most of the land in the 1840s.
Wilmette and Gross Point
Commuter trains began stopping at Green Bay Road and Wilmette Avenue around 1869, and Wilmette incorporated on September 19, 1872, with John G. Westerfield as its first president. To the west, immigrants from the Trier area of Germany built Gross Point around St. Joseph Church, founded in 1843. The village incorporated in 1874 and grew from 327 residents in 1880 to 1,008 in 1910. The two villages grew side by side until Gross Point dissolved in 1919 and joined Wilmette in 1924 and 1926.
Canals, trains and a new lakefront
Clay from the North Shore Channel, dug from 1908 to 1910, became the landfill for Washington Park, later Gillson Park, and the Park Board took shape in 1908 to run it. Sheridan Road, opened in 1900, became the lakeshore route. The elevated line reached Fourth Street and Linden Avenue in 1912, with a Prairie-style station that opened in 1913. Today the channel meets the lake at Wilmette Harbor.
Between the wars
Spanish Court, built in the late 1920s by Edwin Clark, was remodeled in 1967 into Plaza del Lago. During the Depression, WPA crews relaid the brick streets, and markers still sit in the paving at several intersections. They also built the open-air amphitheater in Gillson Park later named the Wallace Bowl. The unincorporated pocket known as No Man’s Land joined the village in 1942.
The postwar village
Wilmette counted 17,226 residents in 1940 and 18,162 in 1950. The Edens Expressway opened in 1951 and Edens Plaza in 1956, and the North Shore Line interurban made its last runs in 1955. By 1970 the population had reached 32,134, and the village marked its centennial in 1972.
