by James J. (James Joseph) Ellis
James J. Ellis, also listed as James Joseph Ellis, was a religious writer whose books centered on Protestant leaders, missionaries, and reformers. Records gathered from library and bookseller listings show works including William Tyndale, Charles Haddon Spurgeon, John Williams: The Martyr Missionary of Polynesia, Mary Slessor, George Müller, and James Hudson Taylor.
His writing appears to have been especially connected with short biographical works meant for a broad audience, often focusing on faith, courage, and missionary service. Several listings identify him as “Rev. James J. Ellis,” which suggests he was a minister as well as an author, though the available sources do not provide a full confirmed life story.
Basic biographical details are limited in the sources I could confirm. One books site lists his lifespan only as ending in 1930, while another reference gives a tentative date range of 1853–1924 with uncertainty, so it is safest to say that he was active in the late 19th and early 20th centuries.
