1902–1994
A psychologist and freethought writer, he is best known for a sharp, plainspoken challenge to religious belief that still feels direct and provocative. His work speaks to readers interested in skepticism, rational inquiry, and the history of secular thought.

by David Marshall Brooks
Born on June 15, 1902, David Marshall Brooks is identified in library and public-domain author records as a psychologist who published as Dr. David Marshall Brooks, sometimes shortened to D. M. Brooks. He is chiefly remembered today for The Necessity of Atheism, a forceful work of freethought first published in the early 20th century.
Brooks wrote in a clear, argumentative style aimed at ordinary readers rather than specialists. In The Necessity of Atheism, he questions religious doctrine, examines how beliefs develop, and argues for reasoned skepticism in public and private life.
Reliable biographical detail about his personal life appears to be limited in the sources available here. The basic dates most consistently attached to him are 1902–1994, and his reputation rests mainly on his contribution to secular and atheist writing.
