Although nothing is known about Hendrickson's secular education, he received catechismal instruction under the direction of the pastor of the Dutch Reformed Church. Hendrickson's primary occupation was that of a farmer, and, like his father, he amassed a large amount of property. About his art Schenck wrote: "He had an unusual genius for painting as without any known instruction and in a creditable manner he executed life-size portraits in oil of himself, several of his family, of a dau. [sic] of Gov. Belcher and also one of the Rev. W. Erickson now in the possession of the author."
