Knickerbacker Monument

The striking monument at the Knickerbacker Parks Memorial Playgrounds is easily visible from quite a distance. It’s located on a steep grassy slope at the rear of the playground complex next to the buildings and athletic field of Lansingburgh High School.
The memorial playgrounds offers everything for the active family —baseball, softball, football, and soccer fields, basketball courts, outdoor skating rink, hockey arena, a big playground, tennis courts, bike paths, and a 400 Meter Oval Track.
We walked over from the baseball monument and it was a long challenging walk up the incline and around an endless chain-​link fence. The monument is a huge granite obelisk at the top of a rolling slope near a bike trail. It might be easier to access the monument from the bike trail…
The view from and around the monument is gorgeous — a sweeping panorama of trees, valleys and green athletic fields.
Sadly, the view around the monument is much better than the condition of the monument itself — we saw quite a lot of painted graffiti everywhere.
The inscription on the obelisk reads:
Thomas Adams Knickerbacker
Helen Louise Knickerbacker
Given in memory of his father and mother by John Knickerbacker
There is also an engraved portrait of the two Knickerbackers.
I unsuccessfully researched who exactly Thomas and Helen Knickerbacker were. I believe their son John (1866 – 1947)was a congressman,
