According to this page which cites Steckel, Richard H. and Roderick Floud (eds.) "Health and Welfare during Industrialization." Chicago: University of Chicago (1997) as a source, the average height of a Frenchman between 1800 and 1820 was 164.1 cm.
According to the French historian, Marcel Dunan (1963):
"If one refers to the Memoirs of Marchand, t. II, 1955, p.338 "the total height of the crown to heel is 5 feet, 2 inches, 4 lines",
or (French measures) 32.47 cm X 5 + 2.7 X 2 + 0.22 X 4 = 1m 68.6.
These measures have been taken by Antonmarchi helped by Marchand.
For its part, the No. 8 (January 1963) Bulletin Quarterly information fields of French St. Helena, the Journal of Andrew Darling, English upholsterer who was responsible for taking exact measurements that I am assisted by General Montholon:
size 5 feet, 7 inches, or (English measure): 30.47 cm X 5 + 2.54 X 7 = 1m 70.
From these two stories we can conclude that the size of Napoleon was not lower 1m 68.6"
Dr. Antommarchi did perform the autopsy on Napoleon. While an original source detailing Dunan's claims appears to be difficult to find, he is cited often in relation to Napoleon's history.
The confusion and misrepresentation of Napoleon's height can be attributed to a combination of the following:
- Napoleon's height was stated to be 5'2 inches. The inches were French rather than British. When converted, it would have been equivalent to 5 feet and 7 British inches which is a respectable height.
- Napoleon surrounded himself with tall bodyguards and had a nickname of le petit caporal. Non-Francophones mistakenly interpreted petit by its literal meaning of "small". In fact, it was an affectionate term that reflected his reported camaraderie with his soldiers rather than his height.
- British propaganda, especially the caricatures by James Gillray built upon this by portraying Napoleon as short and temperamental, and the British as tall and clever.
