Sergey and Larry worked together, and even though they had relatively mediocre computer systems available, they frantically worked at developing new search engine designs and algorithms.
They started doing this basically because they wanted to cause disruption to the Stanford online website infrastructure, but in doing so, they had masterfully created a search engine with massive potential, and all by accident.
They upped their game and the inner workings of the code further and further; perfecting the algorithms and creating the unique PageRank system.
The pair suspended their studies and went on to co-found the company Google Inc. the same Google which we love and hate today.
#9 Sir Richard Branson
Richard Branson is a well-known British industrialist, probably best known for his company the Virgin Group, which holds over 360 different companies.
Richard Branson started his education at Scaitcliffe school in 1963 continued by his attendance at Stowe School in 1965. In 1966 Branson started his first successful business venture; a Student Magazine.
In 1967 Branson started “The Student Advisory Centre” which was a great success. (It advised on topics ranging from sexuality to health, exams to relationships) In many ways it was a precursor to the foundation, Virgin Unite.
In 1970, Branson created another company; which was a mail-order retail business. Its first major success came when Mike Oldfield signed the Virgin Group and had a record which went platinum quickly.
Following the success of Mike Oldfield, more bands signed with the Virgin Group, including The Sex Pistols, which was one of the biggest.
Richard Branson
In 1984 Richard Branson formed the Virgin Atlantic Airways company, or as we know today, virgin Airways; which has been a great success just like many of his previous companies before it.
Probably one of Branson’s most notorious business ventures to date is Virgin Galactic, which is aiming to take passengers into space, which he calls space tourism.
The Virgin Galactic company according to rumor will license the technology behind the so-called spaceship one which is being funded by Microsoft co-founder Paul Allen and Burt Rutan who is an American engineer well-known for his aeronautical work.
Sir Richard Branson is one of the greatest entrepreneurs the UK has ever produced. Without him a lot of things wouldn’t be how they are today, such as the music we listen to, the charities we support, and quite possibly soon space travel.
#10 Thomas Alva Edison
I felt obligated to add Thomas Edison to this list due to his motivation and persistence, which makes him a true entrepreneur, even after thousands of failures.
Although Thomas didn’t have a terrible upbringing in terms of the money sense, he was a poorly child. Ill a lot of his early life, he suffered from a severe ear infection that rendered him deaf in one of his ears, although some say he was deaf in both. He also developed scarlet fever as a boy, nearly dying because of it.
After becoming a minor celebrity for saving a toddler from being hit by a train, Thomas was offered a job as telegraph operator.
Thomas created thousands of inventions and patents, failing a lot more times than succeeding. However, his first 
taste of glory came when he developed the tinfoil phonograph. After working as a telegraph operator, he wanted to create a way of making a telegraph transmitter to work in a more efficient way. He did this by realising that it sounded very similar to spoken words when the tape from the machine was played at a fast pace.
