Theodore Caldwell Janeway (1872-1917): the quest for precision.
The memory of Theodore Caldwell Janeway wafts through the mists of time but faintly. Yet for those few who have read his remarkable book The Clinical Study of Blood-Pressure published in New York in 1904, (see reference 1) he emerges as one of the major clinical scientists in the field of hypertension in the 20th-century. In this monograph he outlines with prescient clarity the limitations of sphygmomanometry and demonstrates the diurnal variability of blood pressure (BP) and the effects of varying stresses on BP. Such was his appreciation of haemodynamics, that had a serendipitous muse been at his side we might speak today of the Janeway rather than of the Korotkoff sounds.
