He is best known for his work in hygiene and his advocacy of woolen clothing for health benefits. Jäger's contributions to the field of natural sciences and his influence on the development of hygienic practices have left a lasting impact.

Early Life and Education

Gustav Jäger was born in Burg, Saxony-Anhalt, Germany. He pursued his education in the natural sciences and medicine, attending the University of Tübingen where he studied under notable professors. Jäger's early interest in the natural world and human health laid the foundation for his future work in hygiene and clothing.

Hygiene and Clothing

Jäger is perhaps best known for his advocacy of woolen clothing, which he believed had significant health benefits. He argued that wool was superior to other materials because it allowed the skin to "breathe" and helped regulate body temperature. Jäger's ideas were published in his influential book, Die Normalkleidung als Gesundheitsschutz ("Standard Clothing as Health Protection"), which gained popularity in the late 19th century.

The Jäger Wool System

Jäger's theories on clothing led to the development of the "Jäger Wool System," a line of woolen garments designed to promote health and hygiene. These garments were marketed as being beneficial for the skin and overall well-being, and they became quite popular in Europe and beyond. The Jäger Wool System was a precursor to modern concepts of functional and health-oriented clothing.

Later Life and Legacy

In his later years, Jäger continued to write and lecture on topics related to hygiene and natural sciences. He remained an influential figure in the field of hygiene until his death in 1917. Jäger's work laid the groundwork for future research into the health effects of clothing and the importance of hygiene in daily life.
