Isaac A. Stevens, who is appointed the Washington Territory's first governor, has declared Olympia to be the territorial capital.

Stevens is also integral in the drafting and negotiation of treaties with native bands in the Washington Territory.

The site of Olympia has been home to Lushootseed-speaking peoples known as the Steh-Chass (or Stehchass; who became part of the post-treaty Squaxin Island Tribe) for thousands of years.

Other natives regularly visit the head of Budd Inlet and the Steh-Chass including the other ancestor tribes of the Squaxin, as well as the Nisqually, Puyallup, Chehalis, Suquamish, and Duwamish.

The first recorded Europeans came to Olympia in 1792.

Peter Puget and a crew from the British Vancouver Expedition are said to have explored the site, but neither recorded any encounters with the resident Indigenous population here.

In 1846, Edmund Sylvester and Levi Smith jointly claimed the land that now comprises downtown Olympia.

In 1851, the U.S. Congress established the Customs District of Puget Sound for Washington Territory and Olympia became the home of the customs house.

Its population has steadily expanded from Oregon Trail immigrants.

In 1850, the town settled on the name Olympia, at the suggestion of local resident Colonel Isaac N. Ebey, due to its view of the Olympic Mountains to the Northwest.

The area has begun to be served by a small fleet of steamboats known as the Puget Sound Mosquito Fleet.

Captain Louis-Marie-François Tardy de Montravel founds Port-de-France (Nouméa) on June 25, 1854.

A few dozen free settlers will settle on the New Caledonia's west coast in the following years.

The Introduction of Municipal Water Filtration in European Capitals (1854)

In 1854, European capitals began implementing municipal water filtration systems, marking a significant advancement in public health and urban sanitation. The initiative was driven by the increasing recognition of waterborne diseases, particularly cholera, which had ravaged European cities in previous decades.

Key Developments in Water Filtration

• Cholera Outbreaks and Public Health Reforms

  • The devastating cholera epidemics of the early 19th century, especially the 1848–1854 outbreaks, underscored the urgent need for clean water supplies.
  • The work of John Snow in London (1854) provided crucial evidence linking contaminated water to cholera transmission, reinforcing the push for filtration.

• Early Filtration Systems

  • London led the way, with the Metropolis Water Act of 1852, requiring sand filtration for water supplied to the city.
  • Other European capitals, including Paris, Berlin, and Vienna, soon followed suit, investing in water treatment infrastructure.

• Impact on Urban Sanitation

  • Water filtration dramatically reduced disease transmission, leading to declining mortality rates in urban areas.
  • These advancements laid the foundation for modern public health policies, influencing later developments in sewer systems and chlorination.

Legacy of 1854 Water Filtration Initiatives

The introduction of municipal water filtration in 1854 marked a turning point in urban hygiene and disease prevention. By ensuring cleaner drinking water, European cities took a crucial step toward modern sanitation systems, significantly improving public health and life expectancy in the decades that followed.

 

Łukasiewicz opens an "oil distillery"—the world's first industrial oil refinery—in Ulaszowice, near Jasło, in 1856.

As demand for kerosene is still low, the plant initially produces mostly artificial asphalt, machine oil, and lubricants.

The refinery will be destroyed in an 1859 fire, but will be rebuilt at Polanka, near Krosno, the following year.

Ignacy Łukasiewicz drills the world's first oil well in Poland, in Bóbrka near Krosno County, in 1854.

While oil had been known to exist for a long time in the Subcarpathian-Galician region, it is more commonly used as an animal drug and lubricant, but Łukasiewicz is the first person to distill the liquid in Poland and in the world and is able to exploit it for lighting and create a brand new industry.

In autumn of 1852 Łukasiewicz, Mikolasch and his colleague John Zeh had analyzed the oil, which had been provided in a few barrels by traders from the town of Drohobycz.

After pharmaceutical methods and processes, the purified oil was obtained and sold in the local pharmacies, but the orders were small due to high prices.

In early 1854 Łukasiewicz had moved to Gorlice, where he continues his work.

He sets up many companies together with entrepreneurs and landowners.

This same year, he opens the world's first oil "mine" at Bóbrka, near Krosno (still operational as of 2006).

At the same time Łukasiewicz continues his work on kerosene lamps.

Later this year, he will set up the first kerosene street lamp in Gorlice's Zawodzie district.

In subsequent years he will opened several other oil wells, each as a joint venture with local merchants and businessmen.

The Zollverein, or German Customs Union, includes all the German states by 1854 save five small northern states and Austria, which the Zollverein totally excludes because of its highly protected industry.
