Eugène-Louis Doyen

Doyen was a skilled and innovative physician who introduced several surgical techniques and medical instruments, some of which bear his name today.

He was a pioneer in the use of electrosurgery and electrocoagulation, and also marketed a yeast extract he called "mycolysine" for treatment of infectious diseases.

He produced numerous films of operations, including a craniectomy, an abdominal hysterectomy, and a surgery for separation of conjoined twins Radhika and Dudhika Nayak, united in the area of the xiphoid process of the sternum.

Although his films were popular at medical conferences abroad, they were harshly criticized by his contemporaries in France, who felt that the integrity of their profession had been compromised.

His controversial public persona often drew attention, as he engaged with high society and made provocative statements about medical practices.
