The gift from Rockefeller’s estate is the largest in the museum’s history. “[His] mother, Abby Aldrich Rockefeller, was one of the founders of MoMA in 1929, and he carried on her legacy, serving as the institution’s chairman and one of its foremost supporters. He was on the museum board from 1948 until his death [in 2017 at age 101].” — Artnet
