Livio Catullo Stecchini (1913-10-06 – September, 1979) was a historian of science, a teaching professor, a scholar of ancient weights and measures (the science of metrology), and of the history of cartography in antiquity. He attended Harvard University, where he was awarded his PhD, and taught at the University of Chicago.
Stecchini's work included many controversial elements, and he complained he was ignored by fellow scientists. His defence of Immanuel Velikovsky in the September, 1963 issue of American Behavioral Scientist magazine (that issue was republished in 1966 as The Velikovsky Affair) also contributed to this.
His work on metrology, based on his work on ancient numismatics, ends in conclusions which are rejected by most academics today, and which some label as pseudoscience. His method consists of starting with an assumption, namely that all ancient measures are by definition related. An old and intriguing idea, but one for which no proof has been found. Based on pure numerical analysis, he reaches his conclusion in "A History of Measures":
No regard is made to the fact that no historical record exists of this relationship. He does suggest some very intricate means by which this could have been executed in practical terms with, again, no evidence from archeology.
Stecchini's analysis of the geometry and methods for constructing the Great Pyramid were interpreted for a popular audience in Peter Tompkins' Secrets of the Great Pyramid with Stecchini's "Notes of the Relation of Ancient Measures to the Great Pyramid," in an appendix to the book.
