Early Life Edit
Tronte Nielsen was born in 1943 to his mother Agnes Nielsen and his Unknown Father.
Tronte moved to Winden in 1953 with his mother, Agnes. They rent a room in Doris Tiedemann's house, where he first meets her daughter, Claudia. Doris briefly asks Agnes about Tronte's father, to which she replies he had died before adding that he was a reverend, but not a good person.
Claudia takes him on a tour of the forest, rejecting the company of Helge Doppler, who sends her dog Gretchen into the Winden Caves out of spite. Later, when alone, Tronte pulls up his sleeve to reveal apparent cigarette burns made on his arms, although the cause is not revealed.
Young Claudia complains to Tronte that her mother acts like she doesn't understand anything. She says when she becomes a mother she will be different. She asks him about his time before they came to Winden. He says his mother was sad all the time, and that she has a brother, but they seem to hate each other. She asks him if she is happy here, but he shrugs. She then asks Tronte if now is a good time and he pulls down his pants.
By 1986, Tronte was working as a local journalist, and unhappily married to Jana Nielsen. He carries on an affair with Claudia, who has been made director of the Winden Nuclear Power Plant. The disappearance of his son Mads shatters the family; Jana becomes distraught and withdrawn, and Ulrich becomes rebellious. Ulrich later discovers that Jana lied to the police when she stated that Tronte was at home with them on the night of Mads' disappearance. Jana assumes that Tronte was with his lover, Claudia.
