The Man Who Tapped the Secrets of the Universe (1946) by Glenn Clark is a work of biography and philosophy, exploring the life and ideas of the versatile artist, writer, and philosopher Walter Russell.
 
New Thought writer and professor Glenn Clark (b. 1882, d. 1956) was a fervent believer in the power of prayer and the Light of God to reveal the secrets of the universe. As he explains in Chapter One: We Go Seeking, he had been searching "...for a man who has discovered the universal law which lies back of the Sermon on the Mount, and who consciously uses that law with full awareness of its meaning, and full obedience to its principles." He believed that he had found that man in Walter Russell.
Walter Russell (b. 1871, d. 1963) was a man who seemed preternaturally adept at everything he wished to try. After being removed from school at the age of nine and sent to work at a dry goods store, he worked a number of low-paying jobs. But he had "absolute faith...that anything can come to one who trusts to the unlimited help of the Universal Intelligence that is within so long as one works within the law and always gives more to others than they expect, and does it cheerfully and courteously."
