It was founded in 1857 by John Evans, one of the founders of Northwestern University, which was established before the city in 1855. The population grew in the late 19th century due to the university, lakefront activities, businesses, and homes. Today, Evanston has a population of around 75,000 and is a diverse community, with attractions including Northwestern University, museums, churches, and restaurants.
