通过研究甘特的朋友邓肯·C·莱尔保存的信件和文章，发现了甘特与泰勒合作期间及晚年独立活动的新信息，包括他参与“新机器”团体及晚年精神状况的疑问。
This article provides fresh insights into the life of Henry L. Gantt by examining the papers of Duncan C. Lyle (1847-1938), Gantt's confidant, friend, and former teacher at the McDonogh School in Maryland. Lyle's papers at the McDonogh School include previously unrecorded articles and personal letters of Gantt's along with articles about him. These materials reveal new information about Gantt during his collaboration with Frederick W. Taylor and during his later years when he acted independently. Of particular interest are items pertaining to Gantt's involvement with a group called The New Machine and the question of Gantt's sanity in his later years.
