Louis Le Chanoine Rendu (1789-1859) was a French geologist and church Canon before becoming Bishop of Annecy. He had a keen interest in glaciers and was the first to observe and describe how the middle of glaciers moved faster then the sides with a motion similar to rivers. Hee described this plasticity and ductile behavior in his 1840 work 'Theorie des Glaciers’. The publication of his original work ignited a controversy between the Irish physicist John Tyndall (1820-1893) and the Scottish glaciologist James Forbes (1809-1868). Tyndall accused Forbes of not properly acknowledging the achievements of Rendu’s studies on glaciers. James Forbes son George Forbes attempted to defend his father by offering full account of the debate in the English translation of Rendu’s 1840 work. He was aided with the translation by the President of the Alpine Mountain Club, Alfred Willis (1828-1912).
