Serving the Nation Since1901
The Hubbard Chart of the Atoms, ca. 1924
Henry D. Hubbard, the designer of the “Chart of the
Atoms,” was the first secretary of the National Institute
of Standards and Technology (then-called the National
Bureau of Standards) and served continuously in that
capacity from 1901 until his retirement in 1938.
Secretary Hubbard made a contribution to instruction
in physics that is still in use today, his modernization of
Mendeleev’s periodic table. First constructed in the
1920s, it has been frequently revised and reprinted.
