The Wartime Botanist
April 24, 1891
Today is the birthday of french botanist Lucien Plantefol.
Lucien developed his own theory to explain how leaves are arranged on the stems of plants. Lucien served in the First World War. Modern chemical warfare began in Lucien's home country, France, on April 22, 1915, when German soldiers attacked the French by using chlorine gas.
Lucien was wounded during the war, but he served his country by working on a national defense laboratory team that developed the gas mask.
