Hugo Matthysen (born 30 January 1956, in Ekeren) is a Belgian (Flemish) singer, guitarist, columnist, writer, Master in Philosophy and actor.

De Hermannen were three people with sunglasses, blonde wedge and wearing black jackets with a white sweater beneath, with which they intentionally looked like the German singer Heino.

He also founded a humouristic rock band, named "Hugo Matthysen en De Bomen", and in 1989 he delivered weekly contributions to the absurd programme Lava by Kamagurka and Herr Seele.

Apart from that, he is the writer of TV series for children like Kulderzipken and Dag Sinterklaas and he is also author of the theater piece Frankenstein by Smrntwsk Alleen (1989).

20 years later, Bart Peeters stated it is thanks to Matthysen that in Belgium the Sinterklaas event has not been subject of a racism discussion as it has been in the Netherlands, because the series explains the figure of Zwarte Piet has nothing to do with slavery.
