A former convent school teacher, Theresa married into the Sackler family, starting her own branch of the dynasty with husband Mortimer J. Sackler. With her late husband one of New York City’s most prominent benefactors, having gifted beyond generous donations to the Guggenheim, the Met, and Columbia University to name a few, Theresa followed in his footsteps and is currently one of Britain’s leading philanthropists. She's been awarded the Prince of Wales Medal for Art Philanthropy, and holds the coveted title of Dame. But, perhaps her most notable, understated position is in serving on the board of Purdue. Homes in London, Berkshire, Switzerland and the French Riviera - must be nice.
