Nikola Tesla
Long overshadowed in public memory by his one-time employer, Thomas Edison, Tesla (1856—1943) was a brilliant scientist and engineer who earned more than 700 patents. He is most famous for developing alternating current (交流电), but his work also led to advances in wireless communications, lasers, X-rays, radar, lighting, robotics, and much more.
Tesla was born to Serbian parents in what is now Croatia, but he emigrated(移民) to the U.S. as a young man, where he eventually became a naturalized citizen. Besides Edison, who later became his bitter rival, Tesla often worked with inventor George Westinghouse. In 1893, the pair demonstrated their advances in lighting and motors in the "White City" at the Chicago World's Fair. In 1895, Tesla and Westinghouse developed the world's first hydroelectric power plant, at Niagara Falls.
At the turn of the century, Tesla set up a laboratory called Wardenclyffe in the small community of Shoreham, Long Island, where he conducted some of his most ambitious experiments. The building was financed by J. P. Morgan and designed by acclaimed architect Stanford White.
The most prominent feature was Wardenclyffe Tower, also called Tesla Tower, a 187-foot-tall metal lattice tower topped with a big antenna that was intended to beam communications and even energy across the Atlantic.Tesla ran out of money while building the tower and was foreclosed(取消赎回权) on twice. As with his previous Colorado Springs lab, assets were sold to pay up his debts. In 1917, the U.S. government blew up the tower, fearing that German spies were using it in World War I. The metal was sold for scrap. For decades, the building was used for photo processing.
"The tower is long gone, but the three-quarter-length statue of Tesla unveiled last week is a fitting memorial," said Alcorn, a retired teacher. "This is the last remaining Tesla laboratory anywhere in the world," she said. "He inspires those who work hard but don't get recognition, and people are starting to recognize how important his contributions are."
As a sign of that growing appreciation, Elon Musk's start-up electric car company Tesla Motors was named after the visionary inventor in 2003.
a. he moved to the U.S. to become an American
b. he entered the Chicago World's Fair
c. he joined in American army in WWI
d. he developed the world's first hydroelectric power plant
e. he built a lab called Wardenclyffe

Guest Reviews (4) Palp from Vancouver ★★★☆☆ Great one hour stop at the Suspension Bridge. The salmon bake in Liarsville was the best part! It was a buffet of UNLIMITED salmon that was being freshly cooked over an open fire. Overall good excursion, just a little too expensive for what it is. Dragon from Los Angles ★★★★☆ Did this on May 1, 2019. Our guide, Glenn, was very enthusiastic and knowledgeable, keeping us entertained all the way by making jokes and explaining the history of the landmarks. There were only 12 people, so we all had window seats!! The views were GREAT! Took lots of pics. Plutocrat from Edmonton ★★★★★ Enjoyed the drive, enjoyed the fees and enjoyed Liarsville, where the food was AMAZING. Can't believe how much we enjoyed walking across the suspension bridge. Rod from Regina★★☆☆☆ "To the Summit" gives the impression you are going to the big summit. This was not the case. The summit in question was just a small hill. The views at the suspension bridge are ok but not incredible. The lunch at Liarsville was not bad, though, and that stop was best of the day. |
