Description
In the late 19th century, the Russian chemist Dimitry Ivanovich Mendeleev developed several charts in which chemical elements were grouped according to common properties. The atomic theory of matter developed over the next century suggested that these groupings could be explained by similarities in atomic structure.
In 1924, Henry D. Hubbard of the U.S. National Bureau of Standards prepared the first edition of this "Periodic Chart of the Atoms." It included symbols for the elements, atomic numbers, atomic weights, and descriptions of atomic structure. In the course of the twentieth century, numerous new elements were discovered and added to the chart. Physical data on the properties of elements also was incorporated. Wall charts became a fixture of the chemistry classroom.
The Periodic Chart of the Atoms was revised regularly by the NBS and published by the W. M. Welch Science Company of Chicago. This is the 1963 version of the chart, as prepared by spectroscopist William F. Meggars. High schools could purchase the charts with aid from the U.S. government. Some chemists working on curriculum projects of the time also prepared new forms of the periodic table.

Comments

I have taught junior high physics for 30 plus years. I inherited this 1963 version, had it restored, mounted on acid-free backing, and framed. I love the patina, the history and am happy to have saved this from the dumpster.
