9. 106 West 53rd Street
Who: Mark Rothko
What: Studio
Now: Midtown Offices

Today if you take a walk down this skyscraper-lined Midtown neighborhood, it seems like just another business district. But there is a forgotten nugget of art history hidden amongst the corporate jungle. Upon his immigration to New York from what is present-day Latvia, Rothko carried out his home life and art career from this residence until his eventual suicide in the apartment's kitchen in 1970.
