Most of our readers will recognize the figure shown in this ad from the August 1939 issue of Practical Mechanics as Lord Baden-Powell, the founder of the Scouting movement. But the ad reveals that B-P was also a proponent of Pelmanism, what the ad calls the Science of Success. It was a system of brain training, which was said to develop the mind just as physical training strengthened the body.

The ad invited you to write in for details of the course in Pelmanism. But thanks to the magic of the Internet, you can now download the entire course for free. If you prefer hard copies, reprints are available at Amazon.
