Mark Twain's secretary
Lyon was born in Tarrytown, New York, to a well-off family. Her father's early death plunged the family into poverty, and Lyon became aDismissal
In March 1909, Lyon married Ralph Ashcroft, a business associate of Twain. At about this time, Twain allegedly began to suspect Lyon of using her position to help herself to his money, particularly for remodeling her house. He also alleged that Lyon was scheming to marry him. It has been suggested that Clara, an aspiring singer, turned Twain against Lyon out of fear that Lyon would expose Clara's extramarital affair with her married accompanist. Another author has said that Twain's charges were accurate and that Lyon was trying to isolate Twain from his daughters, especially Jean, who was epileptic and dependent on Twain for support. Biographer Hamlin Hill defends Lyon is his book, ''Mark Twain, God's Fool''. He states "Isabel probably did expend $2,000 more on the renovations of her cottage than the $1,500 she officially borrowed. That she did so as premeditated embezzlement could only be persuasive to a mind so confused that logical counterargument was unacceptable...She could well have claimed that a fee for the interior decorating of a $45,000 house tormfieldwould have more than covered the costs of her own cottage...Her mistake was in not questioning whether Clemens' loyalty to her was as compelling and powerful as her loyalty to him" (240-241). Twain fired Lyon in April 1909 and forced her to return the property, called The Lobster Pot, that he had given her. Twain was bitter over the affair; he denounced Lyon as "a liar, a forger, a thief, a hypocrite, a drunkard, a sneak, a humbug, a traitor, a conspirator, a filthy-minded & salacious slut pining for seduction." He wrote a 429-page manuscript outlining his complaints against Lyon and Ashcroft. This " Ashcroft-Lyon Manuscript" was kept private by Twain with his intention being to publish it if Lyon were to go public with details of the relationship. It was published in 2015 as part of the third volume of Twain's autobiography.Later years
Lyon and Ashcroft moved to Canada and divorced in 1927, after which Lyon moved to New York and resumed work as a secretary. She seldom spoke of her years with Twain, but she met regularly with Hal Holbrook, who was developing his one-man show '' Mark Twain Tonight''. Lyon died of a heart attack in her Greenwich Village apartment on December 4, 1958, two weeks before her 95th birthday.References
