He signed he instruments 'Le Maire fils' or Le Maire le Fils' up to 1744/5 (1). He signed the marriage contract of Pierre-Alexis Lasnier on 13 September 1734 (2), and it was presumably he who realised the first version of the improved compass of Bouguer and La Condamine (3). In 1740 he made an articial magnet for Nollet who wished to investigate whether it was as useful to arm artificial magnets as it was natural ones (4). He was the first French maker to produce a Hadley quadrant which he subsequently adopted as his shop sign (c. 1739) and worked closely with the academicians Duhamel du Monceau and La Condamine. In 1751 he was juré of the Founder's Company. Speaking of the ability of Butterfield and Joblot in the mounting of lodestones, Nollet in the 1760s stated that now Pierre Le Maire 'les remplace assez bien; & l'on est heureux de trouver dans l'occasion un ouvrier qui entende ce qui fait' (5).
