“Why Change?” by Ralph Beard, 1948, db043r2.
The first Editor of the Duodecimal Bulletin parallels the duodecimal number base with the adoption of Hindu-Arabic numerals and positional notation in medieval Europe. Dozenal must replace decimal, because the latter has “not enough factors” in comparison to dozenal.

Mr. Aitken writes in The Listener makes a case for dozenal, citing fractions and the revolutionary ardor of French promoters of the decimal metric system.


“An Excursion in Numbers” by F. Emerson Andrews.
