Peter Oakley, English soldier and blogger (d. 2014)
Peter Oakley (20 August 1927 – 23 March 2014) was an English pensioner and Internet personality, who posted YouTube videos under the Internet pseudonym geriatric1927. Making his YouTube debut in August 2006 with Telling it all, a series of five-to-ten minute autobiographical videos, Oakley gained popularity with a wide section of the YouTube community. Amongst the autobiographical details revealed in his videos are that he served as a radar mechanic during World War II, that he had a lifelong love of motorcycles, and that he lived alone as a widower and pensioner.

His unforeseen rise was widely reported by international media outlets and online news sources and blogs. After resisting all media attention for a long time (including requests for interviews, photographs, and attempts to identify him), insisting that he only wished to converse with the YouTube community in an informal and personal way, Oakley finally gave his first interview, for the BBC's The Money Programme, which was aired on BBC Two on 16 February 2007.

By mid-2006, Oakley was the most subscribed user on YouTube. His rise to the #1 position took place in just over a week. In the process, he displaced users who had been around since the site's launch, including NBC-signed Brooke Brodack. In November that year, he had 30,000 subscribers. Oakley also holds the record for being the first user on YouTube to reach the milestone of 25,000 subscribers. He uploaded 434 videos between 2006 and 2014 covering several topics from childhood memories to setting up a Google account. He also set up a second channel dedicated to music, Geriatric1927Blues, in 2009.Oakley was later diagnosed with cancer which was too far advanced for treatment. He posted his final video on 12 February 2014 and died a month later on the morning of 23 March 2014.
