many of the objects lent to the museum when it opened were eventually donated to it. among the donors who have shaped the museum's collection are blanche adler, dr. claribel cone and etta cone, jacob epstein, edward j. gallagher, jr., john w. and robert garrett, mary frick jacobs, ryda h. and robert h. levi, saidie adler may, dorothy mcilvain scott, elsie c. woodward, and alan and janet wurtzburger. the growing collection is reflected in the three major expansions: the saidie a. may wing in 1950, the woodward wing in 1956, and the cone wing in 1957. these additions were all designed by local architects wrenn, lewis and jencks to harmonize with the original pope building.
