Who we are
Cross of Lorraine
History of the Double-Barred Cross
Twenty years after Robert Koch discovered the tuberculosis bacteria, workers from many countries met
in Berlin to discuss how tuberculosis could be wiped out. This was a very courageous undertaking as
tuberculosis was still the leading cause of death at the time, outranking famine, war or any other disease.
Dr. Gilbert Sersiron, of Paris, France suggest that as this, too, was
a crusade, it would be appropriate to adopt the emblem of another
crusader, the Duke of Lorraine. Godfrey of Bouillon, the Duke of
Lorraine, was the first Christian ruler of Jerusalem and his banners
bearing the double-barred cross signified courage and success to
Dr. Sersiron's recommendation was adopted and the double-barred
cross became the world-wide symbol of the fight against tuberculosis.
While tuberculosis is said to be "under control" in Canada, it is still a
leading cause of death in many countries of the world.
In Canada, The Lung Association, which began at the turn of the century as the Canadian
Tuberculosis Association, still uses the Cross of Lorraine to signify courage and success
as we continue our battle against all lung diseases.
