Friedrich Ludwig Kreysig

Friedrich Ludwig Kreysig (7 July 1770 – 4 June 1839) was a German physician born in Eilenburg.

In 1795 he received his medical doctorate from the University of Leipzig, and during the following year served as a substitute to Johann Gottfried Leonhardi (1746–1823) at the University of Wittenberg. In 1801 he became a professor of anatomy and botany at Wittenberg.^[1]

In 1803 he was appointed personal physician to Frederick Augustus, and from 1815 served in Dresden as a trainer of Saxon military doctors. For health reasons, he left academic work in 1822, retiring to a private practice, from which he concentrated on botanical studies.

Kreysig is largely known for his work with cardiological diseases. In 1815 he explained inflammatory processes associated with endocarditis.^[2] With physician Ernst Ludwig Heim (1747–1834), the "Heim-Kreysig sign" is named, which in adherent pericardium, an in-drawing of the intercostal space occurs, synchronous with the cardiac systole.^[3]

In 1828, he was elected a foreign member of the Royal Swedish Academy of Sciences.

Kreysig died in Dresden.
