Perhaps most intriguing about Half Day is its name, which provokes more interest and debate than any other place name in the northwest suburbs of Chicago. Contrary to popular theory, the town of Half Day was not named because it was a half day's journey from Chicago. The town's true name was Halfda in honor of a friendly chief. Chief Atakisic (Aphis), of the Potawatomie tribe was a Native American leader of great standing in this area in the early 1800's. The friendly tribes of Potawatomie Indians were the first settlers to arrive in 1730 in what is now known as Lincolnshire. The Chief was instrumental in negotiating the Treaty of Chicago in 1833, and in 1832, during the Black Hawk War; Aptakisic protected the settlers in Downer's Grove from an impending attack. When the first non-native Americans settlers began to move into the area, Chief Aptakisic and his tribe helped Daniel Wright construct a log cabin along the Des Plaines river - the first home built in Lake County.
