John Jr. built the home show his standing in the community and hosted many gatherings here. At the mansion's opening reception in 1901, an orchestra serenaded 700 guests. His daughter Gladys was married twice here, and writer Mark Twain gave a speech to 300 guests in 1902 at a reception of the Hannibal Society.
John Jr. passed away in 1924. The family moved away and the mansion was left vacant for 43 years; eventually, it was scheduled for demolition. Fortunately, three local families saved the house and began restoring it. Work was completed in 1968 and an open house was held on June 14. The mansion has been open to the public ever since.
