Karl Schlögl (October 5, 1924 – May 4, 2007) was professor of organic chemistry at the University of Vienna and secretary as well as vice-president of the Austrian Academy of Sciences.

Schlögl's first contact with organic chemistry happened during his middle-school education, when his father - the principal and teacher for natural sciences - took young Karl to school after hours to do experiments together.

Schlögl was one of the pioneers of the research into the geometric structure of organic compounds and the resulting mechanisms of their chemical reactions.

Schlögl's main field of research since about 1963 was stereochemistry, and in 1970 he began to shift his focus specifically on the chirality of organic compounds.

Schlögl received numerous scientific awards for his work, including the Erwin Schrödinger Prize of the Austrian Academy of Sciences in 1985, [5] the prize for natural sciences of the city of Vienna in 1989, and the Wilhelm Exner Medal of the Austrian Economic Association in 1991.
