Using the name Peter De Koven, I checked all the known artists of the Hudson River School movement but could not find his name listed. However his name comes up in association with it. Not sure and couldn`t find exactly how !! He could have been a property owner in the area or associated in some other way !! You would have to do a bit of research to find the connection !! I did not read the guidebook but the information may be in it !! Just google Peter De Koven, artist and you will find it !! I think it was the first listing. It would be well worth the effort to find information on him !! Hudson River School artists produced many of our great landscape artists such as Frederick Church, Albert Bierstadt, Thomas Moran, great painter of the American west, and others !!
