Herman Hollerith's 1890 census tabulator is one well-known instance. Another, somewhat lesser-known, is Ivan Sutherland's "Sketchpad," developed at MIT in the early 1960s, running on the transistor-based TX-2 computer. Nearly all interactive graphics applications today can trace their roots back to this pivotal
