Dr. Irwin Moon (1907-1986) was the founder of Sermons from Science and Moody Institue of Science, produced a string of movies that were extremely popular in churches. Irwin used science to illustrate biblical truths. His live demonstrations of scientific principles dazzled audiences. Subjects included everything from optical illusions, time and relativity, time-lapse photography of flowers blooming, fish sounds, atomic bombs, honeybees, and almost everything else under the sun in chemistry, biology and physics. A former pastor and Bible teacher, Irwin was an inspiring example of the power of one man's vision to use creative means, geared to the times, to reach millions of people with the unchanging message of the gospel.
