John "Archie" Armstrong Chaloner (né Chanler; October 10, 1862 – June 1, 1935) was an American writer and activist, known for his catch phrase "Who's looney now?".

[4] John Winthrop Chanler's will provided $20,000 a year for each child for life (equivalent to $470,563 in 2018 dollars), enough to live comfortably by the standards of the time.

[6] Chaloner's brother Winthrop Astor Chanler served in the Rough Riders in Cuba[7] and was wounded at the Battle of Tayacoba.

[3] On his twenty-first birthday in 1883, Chaloner inherited the estate at Rokeby along with $100,000 for its maintenance, however after his marriage began to disintegrate, he sold the title to his sister Margaret for a nominal fee and moved to North Carolina.

[10] Chaloner helped found Roanoke Rapids, North Carolina,[11] where he successfully built an electric power-generating station and a cotton mill.

He was declared insane on March 13, 1897, and a New York court recommended that he be permanently institutionalized, however Chaloner escaped the following year and went to a private clinic, where he was deemed able to function in regular society.

[10] He also published several books including Four Years Behind the Bars of "Bloomingdale," or, The Bankruptcy of Law in New York, (1906) and Hell: Per a Spirit-Message Therefrom (Alleged): a Study in Graphic-Automatism (1912).

While he was acquitted of responsibility, Chaloner paid for Gillard's funeral and gravestone, and also suffered a nervous breakdown that caused him to leave Merry Mills for several months.

[3][14] Chaloner became close friends with the Troubetzkoys and also continued to pay Rives a yearly sum of money—events that caused his brother Robert Winthrop Chanler to call him a "looney".
