Jacques Amable Legrand (29 August 1820 – 6 June 1912) was one of the first collectors of French stamps in the nineteenth century and one of the first organizers and scholars of philately in France as a serious topic of study.
He used the pseudonym of Dr.
Magnus.
He participated actively in the journal Le Timbrophile and invented the perforation gauge, or odontometer, which has become a basic tool in determining the perforation of stamps.
He also fought an unsuccessful battle to reject the title of the subject advocated by Georges Herpin and Arthur Maury as "philately" and sought it to be renamed "Timbrology".
