In the 1880s, Mark Twain established and operated his own publishing firm. He also became interested in various investments, especially an elaborate typesetting machine. He lost almost $200,000 in investments in the machine between 1881 and 1894. Also, his publishing company declared bankruptcy (破产) in April 1894. Thus, in January 1895, Mark Twain found himself publicly shamed by his inability to pay his debts.

Mark Twain eventually recovered from his financial difficulties, through his continued writing and a successful lecture tour in 1895 and 1896. During this much-publicized tour, Twain lectured in such places as India, South Africa and Australia. By the time he returned, he had become an international hero. Twain enjoyed this attention, and his habits of smoking cigars or a pipe and wearing unconventional white suits contributed to his showy image. He also made use of his position as a public figure to criticize the US foreign policy.

Although he was recovering from his financial problems by 1898, Mark Twain had begun to experience tragedy in his personal life. Suzy, his oldest daughter, died of meningitis (脑膜炎) in 1896, while her parents and sister Clara were abroad. In 1903, Mark Twain sold the beloved house in Hartford, which had become too closely associated with Suzy’s death. His wife, Olivia, who had developed a heart condition, died on June 5, 1904.
