Human Accomplishment: The Pursuit of Excellence in the Arts and Sciences, 800 B.C. to 1950 is a 2003 book by Charles Murray, most widely known as the co-author of The Bell Curve. Surveying outstanding contributions to the arts and sciences from ancient times to the mid-twentieth century, Murray attempts to quantify and explain human accomplishment worldwide in the fields of arts and sciences by calculating the amount of space allocated to them in reference works, an area of research sometimes referred to as historiometry.
