Carl J. Wiggers

He developed the Wiggers diagram, which is commonly used in teaching of cardiovascular research.

Wiggers achieved world recognition for developing a new method of registering heart and blood pressure, finding the effects of low oxygen pressure on circulation, discovering the effects of valve defects on the heart, studying the effects of shock, and his pioneering efforts along with Dr. Claude Beck and others in techniques of resuscitation from death in the operating room.

After retiring as professor emeritus in 1953, Wiggers joined the Frank Bunts Institute of the Cleveland Clinic Foundation, taking part in postgraduate training for student doctors and in medical and scientific seminars.

Wiggers established and was the first editor of the medical journal Circulation Research and authored seven books and over 300 articles.

Wiggers married Minnie E. Berry in 1907 and had two sons, Harold and Raymond.
