In September of 1997, Harry "Buck" O'Hare approached librarian Suzanne Clark with ways to have a memorial to his parents. Mary said she walked past the stairs one day; looked up toward the landing and was suddenly struck by an idea.  For several years Clark had wanted to put a stained glass window into the library but didn't have the money, so she suggested that the O'Hare's donate money for it.  When they agreed to the idea, Nick Parrendo of Hunt Studios made two designs and the O'Hare family chose one.  Earlier in the year the O'Hare parents had died within 18 days of each other.  They were longtime residents of Bellevue and Harry and his brothers and sisters wanted the community to have something to remember them by.  Mrs. Clark says she was unsure as to what kind of memorial could be used since most memorials in the park are for war veterans.  The design for the window commemorates a tree that stood in the park for approximately 400 years.  A dedication ceremony was held for the window on October 18, 1998.  You can now see it on the landing of the stairs leading to the children's rooms in the library.
