Otmar Gutmann is known for creating the stop-motion claymation series Pingu. In the early 1980s, Gutmann worked with graphic artist Harald Mucke to produce television advertisements, including their first short called Hugo. Gutmann pitched Hugo to Swiss television as "Pingu: A Pre-School Children's Story" and it became a full-time series in 1986. Pingu aired on BBC's Cbeebies until 2015. Gutmann's goal with Pingu was to make it educational for children by not including direct speech, allowing them to decode the visual story and use their imagination.
