Simon-Emmanuel Duplay

Simon-Emmanuel Duplay (10 September 1836, in Paris – 16 January 1924) was a French surgeon who was a member of the Académie de Médecine (1879).

He studied medicine in Paris, obtaining his agrégation for surgery in 1866 with a thesis on umbilical hernias titled De la hernia ombilicale.

In 1880 he became a professor of surgical pathology, followed by a professorship in clinical surgery (1890).

[1] In the late 19th century he provided a comprehensive description of periarthritis of the shoulder, a condition known today as frozen shoulder, and sometimes referred to as "Duplay's disease".

[2][3] With German surgeon Karl Thiersch (1822-1895), his name is associated with an operation for repair of distal hypospadias (Thiersch-Duplay technique).
