Thomas Shadrach James (1 September 1859 – 9 January 1946), born Thomas Shadrach Peersahib, was a Methodist lay preacher, linguist and herbalist. However, it was as a teacher, first at Maloga Aboriginal Mission and later at Cummeragunja Reserve, that he is remembered in history. Through this role, he equipped and influenced generations of Aboriginal Australian activists, including Margaret Tucker, Pastor Doug Nicholls, George Patten, Jack Patten, William Cooper and Bill Onus.
