Emanuel Libman (1872 – 1946) was an American physician.
Libman was a renowned clinician, known for his diagnostic prowess, and interests in bacteriology, pathology and cardiology.
He was one of the first to advocate for the use of blood cultures to diagnose infection, and pioneer in understanding subacute bacterial endocarditis.
Eponymously associated with Libman–Sacks endocarditis (1924), which he defined as atypical verrucous valvular lesions in patients with SLE, along with his student Benjamin Sacks. In 1940, a sample of Libman-Sacks endocarditis was awarded a silver medal at the Meeting of the American Medical Association. Also linked to Libman Streptococcus (Streptococcus enteritis) which he discovered in 1897

Key Medical Attributions
- Pioneer in the fields of in bacteriology, pathology and cardiology
- One of the first to advocate for the use of blood cultures to determine causative organisms in infection
- Influential publications about endocarditis, especially subacute bacterial endocarditis
- Discovered Streptococcus enteritis (Streptococcus Libman) as a cause of focal intenstinal infection
- Published some of the first physical signs and symptoms associated with coronary thrombosis, such as the association between angina pain in essential hypertension and cardiac strain or aortic disease; and acute engorgement of the liver correlating to right coronary artery thrombosis.
- Passionate teacher, researcher and philanthropist. Libman helped to establish numerous funds for medical education and research, including the Edward Gamaliel Janeway Lectureship, the William Henry Welch Lectureship, a lectureship in honour of Hideyo Noguehi at the Johns Hopkins Hospital, the Humphrey Davy Rolleston Lectureship at The Royal College of Physicians in London, the Herbert Celler Fellowship Fund, and the Henry Dazian Foundation for Medical Research.

- Libman-Sacks vegetations
- Streptococcus Libman (Streptococcus enteritis)
- Emanuel Libman Fellowship Fund – established in honour of Libman for his work in medical education
Libman had many famous patients including Gustav Mahler (1860-1911), Fanny Brice (1891-1951), Sara Bernhardt (1844-1923), Thomas Mann (1875-1955) and Albert Einstein (1879-1955)
Libman diagnosed the fatal endocarditis of Gustav Mahler on 25th February 1911. Mahler’s personal physician (Joseph Fraenkel) suspected the onset of endocarditis and called in Libman (‘the world authority and a man of monolithic certainties‘) from the Mount Sinai Hospital. The survival rate in pre-antibiotic days was almost zero. Mahler demanded to be told the truth, then asked to be taken home, to Vienna where he died 2 months later.
