author
Remembered as a theosophical writer, lecturer, and engineer, he moved between practical work and spiritual ideas with unusual ease. His books explore ethics and belief in a clear, thoughtful way.
Sidney Ransom was an English engineer and Theosophist who became known for lecturing, writing articles, and contributing to the wider Theosophical movement. Theosophy Wiki also notes that he was married to Josephine Ransom and was active in the Liberal Catholic Church.
Book listings connected with his name include The Ethics of the Secret Doctrine and The Great Red Frog. Taken together, those records suggest a writer whose work ranged from spiritual and ethical subjects to more imaginative literary projects.
Some art-history sources also refer to a Sidney Lewis Ransom, a British illustrator and designer who used the pseudonym "Mosnar Yendis." Because the available sources here do not clearly prove that this is the same person as the author, that identification is best treated with caution.
