Sources consistently say three of the ten founders of the Cuban Communist Party (1925) were Jewish, which contradicts the claimed four, while the 13 figure appears to refer to the inaugural Central Committee rather than the founders. The claim's core (Jewish founders existed) is supported, but the specific count and denominator are not.

What we found

Contradicts. Multiple sources state that three of the ten founders of the Cuban Communist Party were Jewish, not four of thirteen.[1][2][3][4]

Contradicts. The minutes of the founding session, as cited by the JCFA report, record three Jewish founders out of ten.[3]

Supports. Several sources confirm that Jewish members, including Fabio Grobart, Yoshke Grimberg and Felix Gurvich, were among the party's founders.[1][2][5][6]

Context. The Left Chapter describes 13 members of the inaugural Central Committee, not 13 founding members, suggesting the denominator conflates two bodies.[7]
