F M Alexander, the originator of the Alexander Technique, wrote four books:

• Man's Supreme Inheritance (1910)
• Constructive Conscious Control of the Individual (1923)
• The Use of the Self (1932)
• The Universal Constant in Living (1941)

What is less well-known is the audacious attempt by Ron Brown, a newspaper correspondent and editor in the 1940s, to summarize these four books in one slim volume. As anyone who's read Alexander's books knows, this is no mean feat.
