As I remember, the first true pump hoists (as we know them today) started appearing in southern Michigan in the early 1960s. A popular unit used in our area was made in Ohio. The manufacturer, a drill rig company, had hired an engineer — a real graduate engineer — who came from a drilling family and had drilling experience himself.
Here in the Great Lakes region, with relatively shallow wells, we found the products of this company with this engineer in charge quite innovative. The company, however, sold to a larger company many years ago and moved, I believe, to Oklahoma. Now, we only find the name in the history books, but people still use its products in 2023.
