Henry D. Weenink was born in Wisconsin to Dutch parents in July of 1862. He began his photography career in Wisconsin, where he remained until 1889. At that time he moved west, and set up shop in the small town of Dillon in western Montana. He operated his studios there from 1889 until at least 1903. Aside from producing local images, Weenink also traveled extensively for views and customers. During the early 1890’s he produced images of many parts of the Idaho Territory including Blackfoot, Eagle Rock and Idaho Falls (formerly Eagle Rock), where he operated a "photo tent." Here he sold his photos and took individual subjects for a small fee. On his cabinet mounted photographs his name is also sometimes listed as Weenich or Weeninks, and his first name is occasionally shown as Harry.

To date, only two Yellowstone stereoviews have surfaced by this unsual photographer. Judging from their high quality, it is safe to say that more of Weenink’s Yellowstone images are likely to turn up in the future.
