Friedrich Wilhelm Levi

Friedrich Wilhelm Daniel Levi (February 6, 1888 – January 1, 1966) was a German mathematician known for his work in abstract algebra, especially torsion-free abelian groups.

In 1917, he married Barbara Fitting, with whom he eventually had three children (Paul Levi, Charlotte, and Suzanne).

[2] He contributed to the understanding of combinatorics on words when he articulated the Levi lemma in an article for the Calcutta Mathematical Society.

According to Raghavan Narasimhan, Levi had an important influence on the development of 20th century mathematics in India, especially by introducing modern algebra at the University of Calcutta.

[1] A bibliography of 70 works in mathematics by Levi is included in the 1991 tribute by László Fuchs and Rüdiger Göbel.
