Harry Thumann (28 February 1952 – 2001) was a German electronic composer, record producer and sound engineer. He designed and built groundbreaking synthesizers and studio equipment from the early 1960s onwards. Thumann had a run of what he called "dog records", under the 'Wonder Dog' name, which received some success in Germany and the UK (through E&S Music). The single, "Ruff Mix", peaked at #31 in the UK Singles Chart in September 1982.
