James Dwight (1852–1917) has left very limited information about his life in publicly available sources; all that is currently known is that one work by him survives. That work is entitled Lawn-tennis, indicating that his writing was closely connected with the early development of the sport. Judging from the title, the book was likely a practical guide to the rules, court, and techniques of lawn tennis, intended for enthusiasts and beginners of the time. In the late nineteenth and early twentieth centuries, lawn tennis gradually grew in popularity in Europe and America, and handbooks of this kind helped spread knowledge of the game and standardize how it was played; Dwight's work can be understood in this context. As no reliable records of his birth and death dates, nationality, or profession have been found, further research into the details of his life is still needed, and no speculation is offered here.
