Beside his work on antiseptics, Joseph Lister made many other contributions to the surgery. Among them was the use of catgut ligature.
To find a material stronger than silk, Lister experimented for over a year. Finally he found catgut. Lister became famous all over the world. Surgeons could now do different operations thanks to antiseptic methods. Lister had become a national and world hero. Gradually, other surgeons began to adopt Lister’s methods. They learned that germs in the air were not the chief danger. The big danger came from germs that might be on the hands or clothes of the surgeons or on the surgical instruments or bandages.
