Lionel Logue was an Australian speech therapist best known for his work with King George VI of the United Kingdom. He developed unique techniques to help the king overcome his stammer, which had affected his ability to speak publicly. Logue's methods included relaxation exercises and the use of rhythm and music to improve fluency. Logue's approach to therapy was unconventional for his time, emphasizing the psychological aspects of speech. His collaboration with George VI became widely recognized, especially after the release of the film "The King's Speech," which highlighted their relationship and the challenges they faced together.
