Sweden Travel Guide
Inventions of Sweden

In the 18th century Sweden's scientific revolution took off. Previously, technical progress had mainly come from professionals who had immigrated from mainland Europe. In 1739, the Royal Swedish Academy of Sciences was founded, with people such as Carolus Linnaeus and Anders Celsius as early members. From the 1870s, engineering companies were created at an unmatched rate and engineers became heroes of the age. Many of the companies founded by early pioneers are still internationally familiar. Gustaf Dalén founded AGA, and received the Nobel Prize for his sun valve. Alfred Nobel invented dynamite and instituted the Nobel Prizes. Lars Magnus Ericsson started the company bearing his name, Ericsson, still one of the largest telecom companies in the world. Jonas Wenström was an early pioneer in alternating current and is along with Croatian inventor Tesla credited as one of the inventors of the three-phase electrical system.

The traditional engineering industry is still a major source of Swedish inventions, but pharmaceuticals, electronics and other high-tech industries are gaining ground. Tetra Pak is an invention for storing liquid foods, invented by Erik Wallenberg. Håkan Lans invented the Automatic Identification System, a worldwide standard for shipping and civil aviation navigation. Losec, an ulcer medicine, was the world's best-selling drug in the 1990s and was developed by AstraZeneca. A large portion of the Swedish economy is to this day based on the export of technical inventions, and many large multinational corporations from Sweden have their origins in the ingenuity of Swedish inventors.

Sweden has a total of 33,523 patents as of 2007, according to the United States Patent and Trademark Office, and only ten other countries have more patents than Sweden.
