Albert E Pfaffenzeller (died 1938)

In 1812, on April 30th, Louisiana was admitted to the United States as the 18th state. The area was previously known as the Territory of Orleans.

In 1879, on April 26th, the National Park - later renamed the Royal National Park - the 2nd oldest national park in the world, was formally proclaimed in New South Wales, Australia. It was the first park to have the word "national" in its name.

In 1886, on June 13th, the "Great Vancouver Fire" destroyed most of Vancouver, British Columbia. A small brush fire got out of control and spread to the rest of the city. Dozens of people died and it was only after the fire that money was raised for a fire hall. The local Squamish tribe rescued people who had jumped into bodies of water to escape the conflagration.

In 1905, the Industrial Workers of the World was founded. An international labor union founded in Chicago, it was most often referred to as the "Wobblies" and had ties to the socialist movement and the anarchist movement. At its peak, it had 150,000 members.

In 1938, in the year of Albert E Pfaffenzeller's passing, on June 25th (a Saturday) the Fair Labor Standards Act was signed into law by President Roosevelt (along with 120 other bills). The Act banned oppressive child labor, set the minimum hourly wage at 25 cents, and established the maximum workweek at 44 hours. It faced a lot of opposition and in fighting for it, Roosevelt said "Do not let any calamity-howling executive with an income of $1,000 a day, ...tell you...that a wage of $11 a week is going to have a disastrous effect on all American industry."
