Barbara Kruger
There is a little well known gallery on King Street (778 King St. West to be exact) that only those in the know get to go to. Ydessa Hendeles is a mysterious art curator that only opens her gallery between 12 and 5 on Saturday, Never advertises, has no working website, doesn't tell even the staff when the exhibitions will change or what exhibitions are coming. The best online presence I could find was her portfolio, and that took 6 google pages to get to.
Ydessa has been credited with being one of the 50 most influential people in the art world. She is credited with discovering artists before others realize their import (Cindy Sherman, Christian Boltanski, and Barbara Kruger being but a few). She is one of the best curators today and she is the only independently funded art foundation. Her gallery is always worth a look, despite the effort and inconvenience of getting there.
