From ordinary citizens to astronauts, there are a few people who have done some significant things, but you might not know their name.
We take a look at some notable people from the past (and present) and some of the great things they have done.
Ronald Wayne - Apple founder
Steve Jobs and Steve Wozniak are known worldwide as the founders of the tech-giant, Apple. However, they weren鈥檛 the only ones who started the company, a man called Ronald Wayne was key to Apple鈥檚 establishment in 1976. Jobs and Wayne worked together at the iconic Atari arcade game company, and it is there, where Jobs would regularly turn to Wayne for advice.
Jobs had the initial idea for creating Apple but needed the computer programming skills of the talented Steve Wozniak. Jobs offered Wozniak a partnership but he turned it down, Wayne persuaded Wozniak to start the company and took a background role of an advisor. Apple was born with Wozniak and Jobs having a 45% share each and Wayne with 10%.
Nowadays, owning 10% of Apple sounds like a dream, but Wayne sold his share back to Wozniak and Jobs for $800, just 12 days after the company was founded. This share would be worth over $100bn today. Wayne apparently grew concerned that any debts from the business could fall on him. He said in an interview 鈥淛obs and Wozniak didn't have two nickels to rub together. I had a house, and a bank account, and a car鈥 I was reachable!鈥
Wayne said he has no remorse about giving up his role in Apple but he does have one regret, selling his original signed contract for $500 in the early 1990鈥檚. In 2011, that same document fetched $1.6m at auction, perhaps one more 鈥榳hat if鈥 to add to the list.
Elizabeth Jennings Graham- Civil rights activists
A lot of people know the story of Rosa Parks, a civil rights activist who refused to give up her seat for a white passenger on a bus in Montgomery, Alabama, USA in 1955, but she wasn鈥檛 the first. Nine months before Parks took a stand, a 15-year-old by the name of Claudette Colvin did the same thing in the same town, but this story only made a few local newspapers.
But action against segregation started even earlier. In 1854 a young teacher called Elizabeth Jennings Graham was heading to church in Manhattan, with a friend when she was running late. She hailed the first streetcar approaching and boarded. As soon as the two got on, the conductor tried to drag them back off with Jennings resisting heavily. Eventually a police officer joined in and Jennings was thrown to the pavement.
Her fight for justice didn鈥檛 stop there. Jennings鈥 family got in touch with a young lawyer called Chester Arthur, the same man who would go on to be the 21st US president in 1881. With Arthur鈥檚 help, Jennings successfully sued the railway company in 1855, 100 years before Rosa Parks鈥 famous act of defiance.
Edith Wilson - 鈥楢cting鈥 President of the United States
The US arguably came the closest yet to getting their first female president with Hillary Clinton in the 2016 presidential elections, but some would argue that they鈥檝e already had one. Edith Wilson was the First Lady to the President of the United States, Woodrow Wilson from 1915 to 1921. After president Wilson had a stroke in 1919, First Lady Edith took on a lot of his responsibilities and it鈥檚 argued that she 鈥榩ractically鈥 ran the White House.
Although the President was severely ill and bedridden, he didn鈥檛 resign. Edith carefully looked at all matters that demanded the presidents attention and decided which were important enough to show him. She wrote about her role later saying: 鈥淚 studied every paper sent from the different secretaries or senators and tried to digest and present in tabloid form the things that, despite my vigilance, had to go to the president.鈥
Her version of events has been disputed by some historians.
Hedy Lamarr - Inventor during WW2
In the 1940鈥檚 and 50鈥檚, Hedy Lamarr was best-known worldwide as a Hollywood actress. But behind closed doors Lamarr worked with an American composer-turned-inventor called George Antheil, to come up with a 鈥榝requency-hopping鈥 system. The idea was to stop enemies jamming radio signals between a plane and a guided torpedo, the communications would keep jumping simultaneously to new frequencies.
Lamarr and Antheil patented their idea and took it to the navy but were turned down. In the 1950s, Lamarr鈥檚 technology was being used and in 1962, all of the US ships involved in the Cuban Missile Crisis were equipped with torpedos guided by the 鈥榝requency-hopping system鈥. By this time, their patent had ran out leaving them uncredited and uncompensated. Lamarr and Antheil鈥檚 system is thought to have formed the basis for WiFi, Bluetooth and GPS. All include signals jumping to different frequencies to get the strongest signal.
Hedy Lamarr continued to endure harsh Hollywood schedules, performing in blockbuster films like Samson and Delilah and Algiers. She was loved by fans all around the world, the same fans who had zero knowledge of her work in science. She was eventually recognised in 1997 with an Electronic Frontier Foundation award, who claim to recognise 鈥渓eaders on the electronic frontier who are extending freedom and innovation in the realm of information technology.鈥
Helen Sharman - First British astronaut
When Tim Peake lifted off in 2015, many thought of him as Britain鈥檚 first astronaut but this was far from true.
Although Peak was Britain鈥檚 first 鈥榦fficial鈥 astronaut, meaning he was the first publicly funded Briton in space sent by the European Space Agency, it was actually Helen Sharman who was the first Brit in space. She was part of Project Juno, a 1991 collaboration between the Soviet Union and private British companies.
In 1987, she heard an advert on the radio saying 鈥渁stronaut wanted: no experience necessary鈥 and immediately applied - passing physical exams, psychological and medical tests to be selected over 13,000 other applicants.
She was the only Brit to fly under the UK flag until Tim Peake as other astronauts like Michael Foale and Piers Sellers flew for Nasa under dual-citizenship. She spent eight days at the Mir Space Station, which eventually became disused and was destroyed by Russia in 2001.
Tim Peake, however, was the first Brit to visit the International Space Station.
Stanlislav Petrov - Military Officer who avoided nuclear disaster
During the Cold War in September 1983, the world was saved from a potential nuclear disaster. The Soviet Union鈥檚 early-warning system detected five incoming missile strikes from the United States. Instead of reporting the signals to his seniors, he dismissed them as a false alarm, a decision, which may have saved the world.
The protocol for the Soviet military would have been to retaliate with a nuclear attack of its own. The system was telling him that the level of reliability was at its 鈥渉ighest鈥. Stanislav Petrov told the 大象传媒鈥檚 Russian Service in a 2013 interview: 鈥淭he siren howled, but I just sat there for a few seconds, staring at the big, back-lit, red screen with the word 'launch' on it.鈥
Instead he called the duty officer at the army headquarters and reported a system malfunction. He became suspicious because of how clear the warning was, he says there was 鈥28 or 29鈥 security levels鈥 and he wasn鈥檛 sure that it would pass through all of the checkpoints. If he was wrong, the first nuclear explosions would have happened minutes later.
Twenty-three minutes later nothing had happened. 鈥淚t was such a relief,鈥 Petrov said.
A few days later he was reprimanded, not because of what he did but for mistakes he made in the logbook. He believed that if somebody else would have been on shift, the alarm would have been raised. "My colleagues were all professional soldiers, they were taught to give and obey orders鈥 he said. A later investigation found that Soviet satellites had mistakenly identified sunlight reflection on clouds as the engines of ballistic missiles.
These are just some of the people who have done something notable and many have had a lasting impact on the world today. For those using Wifi on their iPhone, you now know a few people who had an important hand in creating them.
