This is F.M. Alexander (1869-1955), creator of the Alexander Technique, working with one of his students. I am always struck by how present she is. She is upright yet not rigidly so. Calm, yet alert.
She’s doing something apparently ‘normal’ - sitting, yet what’s actually happening is that she is not sitting in her ‘normal’ way.
With Alexander’s guidance, she is exploring a new way of being and of doing things, moment by moment.
