Charles-Paul Diday

Charles-Paul Diday (1812 – January 8, 1894) was a French physician born in Bourg-en-Bresse.

He studied medicine in Paris, and later became chief surgeon at the Antiquaille in Lyon.

In the prevention of the spread of venereal disease in France, Diday advocated mandatory distribution of condoms in houses of prostitution.

[1] He also proposed that all individuals possess a medical certificate of health and disease as a "sanitary passport".

[2] Diday believed that marriage was a prophylactic, stating: "Marriage prevents rapid consumption produced by the venereal excess by excluding the attraction of novelty and subjecting physical instinct to a more sublime moral goal".
