Bernard Lagrange
A little less flashy than most of the guys on this list, Bernard Lagrange has nevertheless earned his reputation as one to watch on the scene. With a degree from Princeton, involvement in the Whitney, and a longstanding career (for someone so young) at Sotheby's, guy clearly knows his stuff. In 2019, it was reported that Gagosian's recently-launched art advisory firm snagged him to join the team in a "high profile hire."
