Hazelden, also known as the George Ade House, is a historic estate located near Brook in Newton County, Indiana. Constructed in 1904, the property served as the country home of George Ade, one of America's most prominent and successful humorists, playwrights, and journalists of the early 20th century. Designed by Chicago architect Billy Mann in the Tudor Revival style, the picturesque home features distinctive half-timbering, prominent gables, and Craftsman-style elements that harmonized with the surrounding Indiana prairie. It was here, at his beloved estate, that Ade wrote many of his famous plays and columns, including his celebrated Fables in Slang, establishing the home as a vital incubator for early 20th-century American literature and humor.

Beyond its architectural charm and connection to Ade's literary career, Hazelden was a major social and political hub of national importance. Ade utilized his spacious estate to host lavish gatherings, community picnics, and high-profile political events. Most notably, the estate served as the launching pad for William Howard Taft's 1908 presidential campaign, drawing a crowd of over 25,000 people to the grounds, and it welcomed other distinguished guests of the era, including Theodore Roosevelt. Listed on the National Register of Historic Places in 1976, the George Ade House stands as a testament to the cultural influence of Midwestern writers during the Golden Age of Indiana Literature and remains a key historical landmark in Newton County.
