Philipp Dettmer is the founder of the channel Kurzgesagt – In a Nutshell, which produces educational animation videos. The videos attempt to explain complex topics in some depth, but in a format that is accessible to non-specialist audiences. The format generally consists of a voiceover that explains the topic at hand, as well as animation for visual aid. The subject matter varies widely, and includes scientific concepts, anthropology, and current events, among other topics.
The Kurzgesagt channel appeared on YouTube on July 9, 2013, and its first video titled "How Evolution works" was uploaded two days later on July 11. The format has remained largely consistent throughout the channel's existence. The video "What Happened Before History? Human Origins", uploaded on June 23, 2016, was the first on the channel to be in 60fps, a trait which all new videos have since possessed. The channel also allows user-submitted captions and subtitles, and it is thus common for Kurzgesagt videos to be subtitled in 30 or more languages.
