Arthur Train (6 September 1875 – 22 December 1945), also called Arthur Chesney Train, was an American lawyer and legal thriller writer, particularly known for his novels of courtroom intrigue and the creation of the fictional lawyer Mr Ephraim Tutt.
Train was born in Boston, Massachusetts. His father was lawyer Charles Russell Train, who served for many years as attorney general of Massachusetts, and his mother was Sara Maria Cheney. Train graduated with a BA from Harvard University in 1896 and LLB from Harvard Law School in 1899.
In 1897, Train married Ethel Kissam. They had four children. Ethel died in 1923 and Train married Helen Coster Gerard, with whom he had one child, John Train.
In January 1901, Train became assistant in the office of the New York District Attorney. In 1904 he started his literary career with the publication of the short story "The Maximilian Diamond" in Leslie's Monthly. He ran the two careers in parallel until 1908 when he left the District Attorney's office to open a general law practice in the Mutual Life Building at 34 Nassau Street in New York City. His 1907 novel, Mortmain, was one of the earliest works in the alien hand syndrome genre and was adapted into a 1915 film of the same name that is now lost.
From 1915 to 1922, Train was in private practice as a lawyer with Charles Albert Perkins while continuing to write, not just novels but short stories, plays, and journalism. In 1919, he created the popular character of Mr. Ephraim Tutt, a wily old lawyer who supported the common man and always had a trick up his sleeve to right the law's injustices. Train wrote dozens of stories about Tutt in the Saturday Evening Post. The fictional Ephraim Tutt became "the best known lawyer in America," particularly after the appearance of Yankee Lawyer, an immensely popular book that purported to be Tutt's autobiography. He also coauthored two science fiction novels with eminent physicist Robert W. Wood. After 1922, Train devoted himself to writing (font: Wikipedia)
