Starting in 1959, music fans Bob and Sid (Sidsel Mari) Gleason of East Orange brought Woody to their 4th floor walk-up apartment at 182 North Arlington Avenue (near the SE corner of Park Ave. and N. Arlington) on Sundays. This provided Woody's New York City friends, family, and fellow musicians a closer opportunity to visit with him regularly.
People hosted by the Gleasons on the Sunday visits included musicians Pete Seegar, Phil Ochs, and the newly-arrived (January, 1961) musician Robert Zimmerman (See Bob Dylan in East Orange). Also visiting were Woody's family who lived in Brooklyn including son Arlo.
In April 1961, Woody was moved to Brooklyn State Hospital; he passed away in 1967.
*The linked Wikipedia article (as of 9/8/2012) is thorough but contains at least one error in that it says Bob Dylan first met Guthrie at the hospital in Brooklyn.
More details of Woody Guthrie's life and his time in East Orange are available in several biographies; excerpts from some of those biographies are available on Google books.
