The development of cheap iron in the US was the major factor that lead to the building of skyscrapers. Being able to produce iron cheaply can be contributed to Andrew Carnegie. This American business mogul perfected the Bessemer process in several factories across the eastern part of the US. From there, he was able to sell cheap iron to American businesses for the purpose of growing their empire.
Robert Kennedy was attorney general during his brother John F. Kennedy's administration.
As attorney general, he fought organized crime and was a key supporter of the Civil Rights Movement.
In 1953 Kennedy became an advisor to the Senate Subcommittee on Investigations under Senator Joseph McCarthy. Kennedy left the position just six months later, objecting to McCarthy’s unjust investigative tactics.
In 1960 Kennedy managed brother John’s presidential campaign. When JFK was elected, Robert was made U.S. attorney general and became one of JFK’s closest cabinet advisors. When JFK was assassinated in 1963, Robert resigned as attorney general the following September and announced his intent to run for a senate seat.
In 1968 Kennedy ran against Eugene McCarthy in the presidential election primaries. On June 5, 1968, following his victory speech at the California Democratic Primary at the Ambassador Hotel in Los Angeles, Kennedy was shot several times by gunman Sirhan Sirhan. He died the next day at age 42, his promising presidential administration over before it began.
