Certainly, it was believed by some(not universal) before 1870 as noted by Pope John XXII (1316-1334) who issued a papal bull condemning it as heresy.

I cannot find a bull from John XXII condemning papal infallibility as heresy. Can you provide a citation?

Think it was bull of 1324 entitled QUIA QUORUNDAM
