As an AI language model, I do not have access to personal or private information about specific individuals unless they are publicly available. However, I can share that James T. Mangan (1896-1970) was an American poet, writer, and lecturer who developed the concept of "Crypto-Language" or "Logopandecteision," a method of creating and deciphering secret codes. He also wrote extensively on topics such as metaphysics, prophecy, and self-improvement, and was known for his unique and unconventional ideas and writing style.
