LENHART, CARL H. (1 Sept. 1880-8 Apr. 1955), surgeon and medical researcher in shock, hemorrhaging, kidney studies, and endemic goiter treatment, was born to country doctor Peter J. Lenhart and his wife Ida I. (Pfeifer) Lenhart in Wauseon, Ohio. He graduated with an A.B. from Adelbert College (1901) and a M.D. from Western Reserve University Medical School (1904). During his residency and internship between 1904-06 at Lakeside Hospital, he did research with Dr. GEO. W. CRILE into the problems of shock and hemorrhaging. Between 1915-20, Lenhart worked closely with Dr. DAVID MARINE in investigating the etiology of simple goiters. As a teacher, he worked in the physiological laboratories of Dr. JOHN J. R. MACLEOD, the codiscoverer of insulin. In 1918, Lenhart became demonstrator of surgery at WRU Medical School. He was appointed instructor later in 1918, professor of clinical surgery in 1930, and head of the school's department of surgery in 1932. In 1921, he was appointed head of the department of surgery at St. Luke's Hospital. Later he was chief (1930-32) of surgery at City Hospital and director (1932-50) of surgery at Lakeside Hospital.
Lenhart, with SAMUEL O. FREEDLANDER, worked out the physiology of the pneumothorax and helped pave the way for open-heart surgery. He worked with Dr. TORALD SOLLMAN on studies of the kidney. He retired from practicing medicine in 1950. In 1952, he was named a trustee of WRU and established the Lenhart Memorial Lecture Fund. Lenhart was survived by his wife, Ora, whom he married on 12 April 1909. They had no children. Lenhart was buried in LAKE VIEW CEMETERY.
