Albert Churchward (1852-1925) was a younger brother of James Churchward, the ‘inventor’ of Mu. Although trained as a medical practitioner, his real passion was the study of the early development of religion and the later development of Christianity from Egyptian origins. In that respect he was greatly influenced by the work of Gerald Massey(a)(c). He makes no reference to Mu or Atlantis, because he either disagreed with his brother’s views or just did not wish to tread on his literary toes! His book The Origin and Evolution of the Human Race can now be read online(b).
