Adrien-Marie Legendre

b. 18 September 1752 Paris
d. 9 January 1833 Paris


There were a number of different methods proposed to find the most likely value of a measured quantity. Legendre proposed the method of least squares. This appeared on pages 72-75 of the appendix to his work Nouvelles M�thodes pour la Det�rmination des Orbites des Com�tes published in 1805. The remainder of the appendix applies the technique to the measure of the degrees of the meridian.

Legendre read on 24 September 1811 a paper to the Academy with the title "Pour trouver le milieu le plus probable entre les r�sultats de diff�rentes observations." This was printed in the M�moires de la Classe des Sciences Math�matiques et Physiques de l'Institut (Vol. 11, 2nd part), pp. 149-154.

A translation of the Appendix into English by George Harvey was published in The Edinburgh Philosophical Journal Vol 7.  Pages 292-301. 

By 1820 we have Nouvelles m�thodes pour la d�termination de l'orbite des com�tes. Second supplement. Paris.

Several other works contributed to the theory of statistics. These are
