His parents worked in the weaving trade. His father is also described as a building worker in at least one source. Walter was the sixth of his parents' seven recorded children. On leaving school, Walter Trautzch successfully completed an apprenticeship in industrial metal forming (als "Metalldrucker"), which was the trade from which he would earn his living, working in various German towns and cities, till 1929. He joined the recently formed Communist Party in June 1923, and participated in the Hamburg Uprising in October of that year. That led to his imprisonment, but he was released in December 1923. He spent six months in Switzerland, but then in 1926 found work closer to home, in Chemnitz. In 1929 his period as an itinerant labourer came to an end when he returned to Lengefeld.

Q: Passage: At the beginning of the 13th century, a Prussian trade route developed that crossed over an isthmus between two large lakes, the Sicienskie lake and the Zamkowe ("Castle lake"). A defensive wall was built at this spot, and later, a settlement was constructed there as well. The place is mentioned in a twelfth-century document regarding a battle in which Henry of Sandomierz was killed. Under the name "Wambresia" the town was mentioned in a 1251 Prussian Document issued at Chemza. Bishop Heidenreich of Bishopric of Chemno received the Chemno Land from the pope. The Polish duke Konrad I of Masovia turned possession of the settlement over to the bishop of Chemno. This created a problem because the Teutonic Knights were in control of the Chemno Land, and a dispute began between the Bishop of Chemno and the Knights. The Pope at the time, Innocent IV, was not keen to continue the dispute and installed the Bishop as the rightful ruler of the settlement. This disagreement was the first historical mention of the settlement. In 1251, a large church, St. Simon and Judah, was built in the city.
