I received Nikola Tesla on cover from Brazil! Nikola Tesla was a Serbian inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Born and raised in the Austrian Empire, Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He immigrated to the United States in 1884, and was naturalized as American citizen in 1891.
Tesla obtained around 300 patents worldwide for his inventions.Some of Tesla's patents are not accounted for, and various sources have discovered some that have lain hidden in patent archives. There are a minimum of 278 known patents issued to Tesla in 26 countries. Many of Tesla's patents were in the United States, Britain, and Canada, but many other patents were approved in countries around the globe. Many inventions developed by Tesla were not put into patent protection.
Thank you very much Sidney!
