Walter Hayle Walshe

Walter Hayle Walshe (1812–1892) was an Irish physician, a pioneer in the study of cancer with his discovery that malignant cells can be recognised under a microscope.

Oliver Wendell Holmes Sr. and François Louis Isidore Valleix, the French physician, were his fellow-students, and continued his friends throughout life.

His pupils maintained that he was the first accurately to describe the anatomy of movable kidney and epidural haematoma, and to teach that patients with aortic regurgitation are likely to die suddenly.

[2] In 1843 Walshe published The Physical Diagnosis of Diseases of the Lungs, later superseded by the Auscultation and Percussion of Samuel Gee, one of his pupils.

He made contributions to medical journals and transactions, and in 1885 wrote the Colloquial Linguistic Faculty and its Physiological Groundwork, of which a second edition appeared in 1886.

He published in 1881 a short treatise called Dramatic Singing Physiologically Estimated,[2] in which he attempted to provide numerically scaled quantifications and categorical qualifications of the operatic or traditional classical voice, based on the qualities of a singer's voice itself, how it used in vocalization, and the dramatic expression employed by the singer and in relation to the two other categories.
