Alaska has seen many different people on her land. In 16,000 BC Paleolithic families moved western Alaska after crossing the Bering Land Bridge. Alaska became populated by a variety of Native Americans. It wasn't until the 18th century that Alaska saw the first European influence, the Russians, although there are reports of them settling there much earlier but there is no written indications proving that.
Russia decided that Alaska was one of the best places in the world for fur and quickly established fur trading posts. The Russian-American Company was created for fur trade. It wasn't too long before the land became over hunted. That and the reliance on American supply ships meant the profits of fur trading began to fall. Rather than let the British try to take control of Alaska, Russia sold it to the United States and the Russian-American Company was dissolved.
Russia wasn't the only one who tried to lay claim to Alaska. Spain also sent expeditions form Mexico to explore Alaska in 1775. They stopped at a few places and renamed a few things. And eventually headed back south after a few months. Another expedition was sent in 1791 to search for the Northwest Passage. They ran into the Tlingit tribe and studied their way of life. But it proved toward the end that the rivalry was too much and withdrew with only a few place names kept such as Malaspina Glacier and the town of Valdez.
Not wanting to be left out, the British followed in pursuit of Alaska, in Spain's wake. James Cook, who also has famous ties to Hawaii, mapped the west coast up to the Bering Strait, which proved to be impassable. Even after Cook died in Hawaii after visiting Alaska, his crew continued to sell fur that they had bought in Alaska for a very high price which spurred the British to increase their presence in Alaska.
In today's Russia, there is a myth that still circles, that Russia did not sell Alaska to the United States, but rented the land for 100 years. There also was another myth that circulated that the Untied States deal with Russia was a direct result of bribery and that the United States manipulated the stocks of the Russian American Company. However, the United States bought Alaska from Russia on April 9th 1867 for $7, 200, 00 in gold coins. That would equal to $90, 750, 00 today. The purchase of Alaska was known as "Seward's Folly". At the time the purchase was unpopular until later it was discover that gold was in Alaska.
Alaska was considered the Department of Alaska until 1884. There was no government there yet and Alaska stayed under the jurisdiction of the U.S. Army until 1887. The United States Department of Treasury took over from 1877 to 1879. It then shifted hands again to the U.S. Navy for 1879 to 1884.
Alaska changed names again to the District of Alaska. But government was too busy with reconstruction after the Civil War to devote any time to Alaska. After gold was discovered in the Yukon Territory in 1896, the U.S. economic depression ended over night. Although gold had not been discovered Alaska yet, but miners had to travel through Alaska to get to the gold rush. It wasn't until 1899 that gold was discovered in Alaska and even more towns were built. Copper mining, fishing and canning also became popular and helped build the population in Alaska.
In 1916 Alaska's population reached 58,000 and renamed the Territory of Alaska. It was also reorganized. It wasn't until July 7th 1958 the President Eisenhower signed the Alaska Statehood Act. Alaska's admission to the U.S. was finalized and recognized as the 49th state on January 3rd, 1959.
Brief History Of Greece
Today, air purifiers are all the craze. Every allergy sufferer, asthmatic and health nut in the world has one, but believe it or not, there was a time when we didn't have air purifiers. We simply breathed the air that was in our homes and somehow managed to survive. So when did this craze actually begin? How did it start?
Types of air purification have actually been around for over 200 years in some form or another, though most people don't realize it. The truth is, since the early 1800s, scientists have been trying to find ways to make our air cleaner, long before the industrial revolution ever hit and California began to look like an outdoor barbecue on a high flame.
To kick this technology off, in the early 1800s John and Charles Dean developed a mask for fire fighters. This mask allowed them to charge into burning buildings without having to worry about being overcome by smoke fumes from the fire. Around that same time, masks were also made for divers and coal miners who were constantly exposed to dangerous air, but it wasn't until the 1850s that the first gas mask was developed by John Stenhouse. The mask worked on a charcoal based filter design, very similar to some of the air purifiers today. These original masks worked on the principal of filtering out what they called "enemies" by using a system called High Efficiency Particulate Air or HEPA. Yes, the same HEPA filter systems we can buy today. Once they added charcoal to this system it made a dramatic improvement because the charcoal was able to filter out multiple toxins.
But it wasn't until World War II when we got some of the greatest advancements in air filter systems. This came with the Manhattan Project. This was a project that got scientists together from all around to work on a breathing device that would protect soldiers from the atomic bomb. While that was actually laughable in itself, it did end up in advancements that helped combat chlorine gas, mustard gas and flame throwers. A few years later a plague in Africa made scientists aware of the need for protection against chemicals, perfumes, building materials, pesticides, dust mites, pollen and food allergens. This started a string of air purification devices being developed.
In spite of all this, it wasn't until the 1980s that the clean air craze really took off. The concept of a dust free environment was all the rage, practical or not. According to studies, HEPA filters, which were the biggest rage of the era, filtered out 99.7% of all the allergens in the air and all micron offenders of size 0.3 and larger. But advancements didn't stop there. Newer devices, such as Nebulizers, were able to filter out offenders of size 0.1 and larger and still keep the 99.7% filter level.
Over the years, the number of devices used for filtering the air has grown astronomically. Just do an Internet search on the different types and brands of air purifiers. There are literally hundreds of them.
All this from a simple mask designed for fire fighters. Who would have ever guessed?
