# Anton Weichselbaum

Anton Weichselbaum (8 February 1845 – 23 October 1920) was an Austrian pathologist and bacteriologist. He was among the first scientists to recognize the importance of bacteriology for the field of pathological anatomy.

## Biography

Weichselbaum was born on 8 February 1845, near the town of Langenlois.

In 1869, he received his medical doctorate in Vienna, and subsequently worked as an assistant to pathological anatomist Josef Engel (1816–1899). In 1885, he was appointed an associate professor of pathological histology and bacteriology, and from 1893 to 1916, he was director of the pathological-anatomical institute at the University of Vienna. In 1912, he became university rector.

Some of his better known assistants were serologist Karl Landsteiner (1868–1943), bacteriologist Anton Ghon (1866–1936) and dermatologist Josef Kyrle (1880–1926).

In 1887, he was the first to isolate the causative agent of cerebrospinal meningitis, a bacterium he named Diplococcus intracellularis meningitidis. He conducted important research involving tuberculosis, and is credited for founding the first Lungenheilstätte (pulmonary health institute) in Austria (Alland, Niederösterreich). Also, he provided the first comprehensive description of local bone erosion in arthritis.

Weichselbaum was a son-in-law to chemist Franz Schneider (1812–1897). Weichselbaumgasse, a thoroughfare in the Favoriten district of Vienna is named in his honor.
