The golden spike (also known as The Last Spike) is the ceremonial final spike driven by Leland Stanford to join the rails of the First Transcontinental Railroad across the United States connecting the Central Pacific and Union Pacific railroads on May 10, 1869, at Promontory Summit, Utah Territory. The term last spike has been used to refer to one driven at the usually ceremonial completion of any new railroad construction projects, particularly those in which construction is undertaken from two disparate origins towards a meeting point. The spike now lies in the Cantor Arts Center at Stanford University.

History

Completing the last link in the transcontinental railroad with a spike of gold was the brainchild of David Hewes, a San Francisco financier and contractor. The spike had been manufactured earlier that year especially for the event by the William T. Garratt Foundry in San Francisco. Two of the sides were engraved with the names of the railroad officers and directors. A special tie of polished California laurel was chosen to complete the line where the spike would be driven. The ceremony was originally to be held on May 8, 1869 (the date actually engraved on the spike), but it was postponed two days because of bad weather and a labor dispute that delayed the arrival of the Union Pacific side of the rail line.

Usain Bolt

Usain St. Leo Bolt, OJ, CD (/ˈjuːseɪn/; born 21 August 1986) is a Jamaican sprinter. Regarded as the fastest person ever timed, he is the first man to hold both the 100 metres and 200 metres world records since fully automatic time measurements became mandatory in 1977. Along with his teammates, he also set the world record in the 4×100 metres relay. He is the reigning Olympic champion in these three events, and the first man since Leonidas of Rhodes to win six Olympic gold medals in sprinting, and an eleven-time World champion. He was the first to achieve the "double double" of winning 100 m and 200 m titles at consecutive Olympics (2008 and 2012), and topped this through the first "double triple" (including 4×100 m relays).

Although gaining worldwide popularity for a sprint double victory at the Beijing Games, Bolt has had more victories as a 200 m runner. While he had not won any significant 100 m title prior to the 2008 Olympics, he had won numerous crowns in the 200 m event at the youth, junior and senior levels. Further, at the 2013 World Championships in Moscow, Bolt completed a hat-trick of 200 m world titles by winning his third straight gold in the event. His 2009 record breaking margin for 100 m, from 9.69 seconds (his own previous world record) to 9.58, is the highest since the start of fully automatic time measurements.
