Arthur Looss

Looss was sent by Rudolf Leuckart to Egypt to study the transmission of bilharzia, where he became accidentally infected with hookworm, and in so doing discovered the method by which the larvae penetrate the skin.

He examined his faeces at intervals and found hookworm eggs in it a few weeks later.

The paper he wrote about the life cycle of the hookworm is considered a classic in the field.

[3] Looss continued to work as a professor of parasitology and biology in Egypt until the outbreak of the First World War.

It is reported that "Looss' enthusiasm and energy as a research worker have probably seldom been surpassed, and all his work was characterized by a painstaking attention to detail that is unfortunately rare".
