Frederick Matthias Alexander lost his voice during his career as a Shakespearean actor in Melbourne in the 1890s.
Recognising that the way he was using his head-neck region while reciting was causing the damage to his vocal chords, he applied himself to what he expected would be a straightforward correction of faults.
What he discovered in his ten-year endeavour was that successful performance of any human activity was dependent on good use of the whole person.
He later developed a means of imparting his new ideas of restoration of good poise and co-ordination to complainants of all manner of use-related malfunction and injury.
His unique method has come to be known as The Alexander Technique, and is now taught world-wide as a means of improving general health and addressing common disorders such as back pain that derive from poor posture.
