Several prominent members of the Harvard faculty belong to the group, including History Department chairman Sidney Chalhoub. The Brazilian historian has sparred with Harvard leadership in the wake of Hamas's Oct. 7 attack on Israel—in November, he signed a letter condemning the school's "Combating Antisemitism" initiative, which he and other signees called "dangerously one-sided."

As chair of Harvard's history department, Chalhoub "play[s] a key role in the life of the department," according to a 2022 university handbook. He is responsible for developing the department's "curricular plan"—the history classes Harvard will offer—as well as recruiting and promoting faculty and overseeing "the process for graduate student admissions." Chalhoub also resolves "departmental disputes," holds "regular department meetings and social occasions that help to build community," and monitors "tenure-track faculty," according to the handbook.
