diseases rapidly spread through unsanitary conditions and were difficult to treat with the rudimentary medicines available Today, life in the United States and other developed countries is about ease and convenience Communication is global and instantaneous Transportation can carry people across states, countries, and even entire continents in a matter of hours Industry has been automated, providing people with plenty of time outside of work to enjoy leisure pursuits Modern medical treatments have enabled people to stay healthy well into their eighth, ninth, or even tenth decade Life has been transformed over the years through the efforts of the men and women who had the brilliance, diligence, and creativity to come up with new and better ways of doing things As detailed throughout these pages, their inventions spawned many more inventions, speeding up the pace of progress even further Alexander Graham Bell’s fascination with the idea of sending sound down a wire from the speaker to the listener gave birth to the telephone, which ultimately led to the cell phone, fax machine, modem, and a communication system that now links the entire globe These inventions, like many others, have clearly improved life by keeping people healthier, helping them to communicate and work more efficiently, and allowing them to travel farther X-rays allowed doctors to look inside the human body to treat disease and injury The electric light illuminated the darkness so people could The 100 Most Influential Inventors of All Time work (and play) at night Braille made it possible for blind people to read However, some inventions, while having their obvious benefits, have also had their pitfalls Before Eli Whitney invented the cotton gin in 1793, separating cotton lint from its seeds was a 10-hour, labour-intensive ordeal Whitney’s invention transformed cotton production into a rapid process that for the first time made cotton farming a highly profitable business Yet the cotton gin also prolonged slavery, as cotton plantations needed a larger labour force to keep up with increased production demands Other inventions were controversial because of their potential for destruction Edward Teller, father of the hydrogen bomb, was described by one scientist as being one of the “most thoughtful statesmen of science.” However, another contemporary referred to Teller as “a danger to all that’s important,” and claimed that the world would have been better off without him In 1948, Paul Hermann Müller received a Nobel Prize for discovering the toxic effects on insects of the chemical compound known as DDT, a pesticide that efficiently wiped out the insects that carry deadly diseases such as malaria, yellow fever, and typhus DDT was initially hailed as a “miracle” pesticide Yet by the early 1970s it had been banned from public use in the United States Health officials had discovered that while DDT was killing insects, it was also accumulating in other wildlife, notably falcons and eagles, and dangerously lowering their reproduction rate Even the most groundbreaking and world-changing inventions were not always recognized as such when they were introduced to the public When Rutherford B Hayes saw a demonstration of Alexander Graham Bell’s telephone in 1876, the president’s response was less than enthusiastic “That’s an amazing invention, but who would 10 ... and the other a device (the details of which are uncertain) for mechanically 21 The 100 Most Influential Inventors of All Time representing the motions of the Sun, the Moon, and the planets The. .. the Greek god of 19 The 100 Most Influential Inventors of All Time medicine, Asclepius He is considered to have been the architect of the step pyramid built at the necropolis of Saqqārah in the. .. for the area A of a triangle, A = √(s(s−a)(s−b)(s−c)) in which a, b, and c are the lengths of the sides of the 23 The 100 Most Influential Inventors of All Time triangle, and s is one-half the
