Leonard Landois (born December 1, 1837 in Münster , † November 17, 1902 in Greifswald ) was a German physiologist.

Life

Landois was the son of the official Theodor Ferdinand Landois (1794–1868), who was born in Münster. He came from Lorraine on his father's side and his wife Antoinette Josephine Pollack (* 1834), who was also from Münster. The zoologist Hermann Landois was his brother.

Landois completed his school days at the Paulinum grammar school in Münster and began to study medicine at the University of Greifswald in 1857 . He successfully completed this course in 1861 with his dissertation on parasites . The following year he passed the state examination and then worked for a few months as a general practitioner in Münster, where he made a name for himself primarily as an obstetrician.

He then became an assistant at the Anatomical and Physiological Institute in Greifswald, where he was able to complete his habilitation in 1863. In 1867 he married Clara Helene, a daughter of the botanist Theodor Marsson . With her he had a daughter Clara and two sons named Felix Landois , who later became a surgeon, and Max Landois , who later became an imperial judge. In 1866 Landois was elected as a member of the Leopoldina .

With effect from July 1, 1868, he was appointed associate professor of anatomy and physiology; 1872 full professor. As such, he was appointed director of the physiological institute. During this time, Landois was instrumental in ensuring that the institute was able to move into a new building. He also carried on the research of his teacher Julius Budge (1811–1888). One of Landois' most important students was the Münster physiologist Rudolf Rosemann (1870-1943). His research was interrupted by his participation in the wars of 1866 and 1870/71 as a field staff doctor.

Leonard Landois was a pioneer in the study of blood transfusion , this is how he described the phenomena of agglutination . Landois describes the process of agglutination or hemolysis without recognizing its importance with regard to a blood group classification. In 1875 he showed that red blood cells , erythrocytes from one animal species meet or are mixed with the blood serum of another animal species, the red blood cells typically clump and sometimes burst ( hemolysis ). After detailed physiological studies and the evaluation of case studies, he rejects the lamb blood transfusion and warns of the deadly potential of this measure.

Leonard Landois was the first secretary of the Greifswald Medical Association , which was founded on August 1, 1863, and was its chairman in 1887/1888, 1889 and 1899/1900. He was a member of the scientific association for New Western Pomerania and Rügen.

Leonard Landois died in Greifswald on November 17, 1902 at the age of 65.
