Louis-Joseph d'Albert de Luynes

Louis-Joseph-Charles-Amable, Comte d'Albert, Duc de Luynes (1748– 1807) was a French aristocrat, military and politician, who was also a member of the Assassin Brotherhood.

At some point before the French Revolution, D'Albert and three other Assassins were sent by the Mentor to recruit a skilled epeist and singer called La Maupin, but due to D'Albert vanity and misogyny a fight erupted. The three Assassins were defeated and La Maupin put her sword through D'Albert's shoulder, and the group left to make their report. In the report redacted by the Master Assassin Maréchal on the incident, the latter stated that D'Albert was an "ass" and that no more mission of recruitment was to be confided to him as no "porcelain should be entrusted to a baboon''.

Eventually, despite a difficult first contact, La Maupin joined the Brotherhood as Maréchal stated that he personally trained her to hone her skills in acting despite D'Albert statement that she was not a good recruit.
