Minnesota’s Twin Cities have seemingly always enjoyed a thriving cultural scene far larger than a medium-sized metropolitan area could reasonably be expected to support. The quiet secret to the region’s artistic success has been a long history of private stewardship, spearheaded by a succession of ultra-rich benefactors who have poured a sizable chunk of their net worth into orchestras, museums, and theaters. There have always been doomsayers who warn that once the existing generation of philanthropists dies off, the Twin Cities arts scene will wither on the vine. But recent evidence suggests that a new generation of supporters is ready and able to take the reins.
