Did you know?
In 1884, in the year that Mary Hopper was born, on May 1st, the Federation of Organized Trades and Labor Unions - a US association - first resolved that "eight hours shall constitute a legal day's labour from and after May 1, 1886, and that we recommend to labour organisations throughout this jurisdiction that they so direct their laws as to conform to this resolution by the time named." Previously, workdays would consist of 10 to 16 hours a day - 6 days a week. It would take years before the 8 hour workday became common practice - and longer before it became a law.

In 1900, by the time she was 16 years old, 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.
