Did you know?
In 1884, in the year that John Trosvig 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.
Did you know?
In 1896, he was merely 12 years old when in April, the first study on global warming due to CO2 - carbon dioxide - in the atmosphere was published by Swedish scientist Svante Arrhenius. Arrhenius concluded that human activity due to the Industrial Revolution would amplify CO2 in the atmosphere, causing a greenhouse effect. His conclusions have been extensively tested in the ensuing 100+ years and are still seen to hold true.
