He worked on the show from 1978 to 1983 as special assistant to Peter Röders and his character of Samson, and helped Benita Steinmann with her performance of Uli von Bödefeld when he joined the cast. Klose originated the character of Finchen, when he was introduced in 1983. He was not asked to continue performing the character when new episodes of the show went into production a couple of years later, as an entirely new team was assembled in 1986.
