Edwin Allen Locke
Edwin Allen Locke (1874-1971) was an American Physician
Much of his work and interests within medicine involved care and treatment of tuberculosis and pulmonary disease.
Collaborated with Richard Clarke-Cabot and noted an early diastolic murmur, heard in untreated anaemia, with normal valvular anatomy. The murmur sounds similar to aortic regurgitation, but without a decrescendo and resolves with the treatment of anaemia – the Cabot-Locke murmur (1903).

Medical Eponyms
Cabot-Locke murmur (1903)
The Cabot-Locke murmur is an early diastolic murmur found in patients with severe anaemia. The murmur resolves with treatment of the anaemia. There is no functional valvular abnormality present. Unlike the early diastolic murmur associated with aortic regurgitation, the Cabot-Locke murmur has no associated ‘decrescendo’ phase.
Note: The description of the Cabot-Locke murmur was based on a study sample of three patients…
In cases of intense anaemia, when the red cells are reduced to or below 1,000,000 per cu. mm, one occasionally hears diastolic murmurs not to be explained by permanent dilatation of the aortic ring nor as “cardio-respiratory murmurs”, and not due to a diastolic accentuation of a venous hum. The cause of these murmurs is obscure
