Happy 90th Birthday David Attenborough!

The most recognisable voice on television and the godfather of natural history turned 90 on Sunday! To celebrate, we're taking a look back at the beloved broadcaster's five best moments, plus here are five things you might not know about him...

1. He was turned down by the BBC
   Sir David's first job after completing a degree in natural sciences at Cambridge was in the navy. He completed two years of national service stationed in North Wales and the Forth of Firth. He then briefly worked in children's textbook publishing before applying for a job at the BBC in 1950. His application was initially rejected, but his CV was reviewed shortly afterwards and he was given three months' training. He once said that if he hadn't got into television, he might have become a teacher.
   
   
   
2. His teeth were a problem
   Like many Britons at the time, Sir David didn't own a television when he started working at the BBC and had only ever watched one TV programme. He worked on natural history programmes but was discouraged from appearing on camera because he was told his teeth were too big. However, he was asked to step in as a presenter on Zoo Quest in 1954, when the scheduled presenter fell ill.
   
   
   
3. He commissioned Monty Python and rejected Wogan
   Sir David became controller of BBC Two between 1965 and 1968, during which time he introduced colour television to Britain and commissioned an eclectic mix of programming, including Monty Python's Flying Circus. However, he politely turned down an application from Sir Terry Wogan to be a BBC presenter. "We do not have any vacancies for anyone with your particular talents and experience," he told the presenter, pointing out that BBC Two's chief presenter Denis Tuohy was also from Ireland. "To have had two Irishmen presenting on BBC Two would have looked ridiculous," Sir David said earlier this year.
   
   
   
4. He is one of the most travelled men in history
   In a 2012 edition of Desert Island Discs, presenter Kirsty Young claimed Sir David "has seen more of the world than any person who has ever lived". While this might be hard to prove, it is true that in order to film the Life of Birds series alone, the naturalist had to travel more than 256,000 miles, the equivalent of going around the world ten times. Despite his travels, Sir David told Time Out that his favourite place in the world was Richmond upon Thames in Surrey.
   
   
   
5. He hates rats
   He has got up close and personal with a lot of scary creatures in his 60-plus years of programme-making, but Sir David has an "irrational horror" of rats. "If a rat appears in a room, I have to work hard to prevent myself from jumping on the nearest table," he told Wales Online. His loathing started during a thunderstorm when he was staying in a thatched hut in a village in the Solomon Islands. Something ran across him as he was sleeping and when he flicked on his torch, he saw rats everywhere. He adds that his horror also comes the fact that rats live so close to humans and don't have any real fear of us.
