In 1900, in the year that Isadore Plotnick was born, the German physicist Max Planck formulated an energy theory, postulating the existence of "quanta," which lays the groundwork for the quantum theory of modern physics. In December, he introduced a paper on the Planck postulate which stated that E=hv - the energy of a photon is proportional to its frequency times a constant. Planck won a Nobel Prize in 1918 for his work in theoretical Physics.

In 1913, by the time he was just 13 years old, ratified in February the 16th Amendment, establishing a Federal income tax, became law. Previously, customs duties (tariffs) and excise taxes were the primary sources of federal revenue. With the passage of the 16th Amendment, incomes of couples exceeding $4,000, as well as those of single persons earning $3,000 or more, were subject to a 1% Federal tax (that would be about $98,000 and $74,000 now). Rates rose to 7% for incomes over half a million dollars. Less than 1% of the population was subject to income tax.
