Victor Eisenmenger

The son of portrait painter and professor August Eisenmenger, he attended the University of Vienna and became the personal physician of Archduke Franz Ferdinand.

Eisenmenger's syndrome – a phenomenon in which longstanding heart defects affect the blood flow to a person's lungs – is named in his honor.

Von Schrötter, who had become something of a father figure to Eisenmenger, arranged for him to become the personal physician to the Archduke Franz Ferdinand, who had just been diagnosed with tuberculosis.

[6] Even before it was published, the work generated some controversy among Viennese physicians because Eisenmenger included information that was thought to violate standards of doctor-patient confidentiality.

Archduke Leopold of Austria, Prince of Tuscany was jailed on a grand larceny charge in the matter, but he was acquitted at trial.

[8] In an 1897 article in a German medical journal, Eisenmenger described signs of low blood oxygen levels (including a bluish hue to the skin and nail clubbing) in a 32-year-old man who had been born with a ventricular septal defect.
