H. Ernest (Harry Ernest) Hunt

Before devoting himself fully to writing and lecturing, he worked as a tutor at St. Paul's School in London. Reference sources describe him as a British spiritualist and author who turned his attention to practical psychology and related subjects.

His books reflect a wide range of interests, including mental training, meditation, the hidden mind, health and happiness, and the relationship between spirituality and music. Works associated with him include The Hidden Self and Its Mental Processes, The Influence of Thought on Health, Wealth, and Happiness, Self-Training, How to Meditate, and Spirit and Music.

Public-domain library records also show that his work has remained available long after his lifetime, suggesting a lasting niche readership among people interested in spiritual thought, self-culture, and the psychology of everyday life. I couldn't confirm a suitable portrait image from the sources I checked, so none is included here.
