Arielle Tepper is one of Broadway’s youngest impresarios, “armed with the romantic notions of a stage-door Annie, the energy of youth and, not incidentally, a considerable fortune derived from the real estate empire of her maternal grandfather, Philip Levin, who died in 1971, the year before Ms. Tepper was born. In 2001, Ms. Tepper inherited a third of the family real estate portfolio, which Crain’s New York recently estimated at $1 billion. Ms. Tepper has used part of her share to make herself into an eager new player in the treacherous world of theatrical producing.”
