author
1868–1926
A preacher and religious autobiographer, he is best remembered for tracing his own path from skepticism back to Christian faith in a candid, plainspoken memoir.

by Henry F. (Henry Frey) Lutz
Henry Frey Lutz was an American religious writer and evangelist born in 1868 and died in 1926. The main work clearly associated with him online is To Infidelity and Back, a religious autobiography first published in the early 20th century and preserved by Project Gutenberg.
That book presents a personal story of doubt, searching, and return to belief. Available descriptions consistently frame it as the account of a truth-seeker wrestling with rationalism, Unitarianism, and Christian conviction before embracing faith again.
Reliable biographical detail beyond those basics is limited in the sources I could confirm, so this portrait stays brief. What does come through clearly is a writer interested in spiritual struggle, persuasion, and the lived experience of belief.
