The Theo Klein company was founded in 1949 by Theo Klein and his wife Maria Klein as a brush and broom factory. In 1956, the company manufactured the first colored children's broom with plastic bristles with the idea of expanding the available range of products. In retrospect, this idea was the starting point for a real success story. The first participation as an exhibitor at the Nuremberg Toy Fair in 1959 (with only 3 products: children's broom, hand brush and metal shovel) completed the move of the company into the toy industry. The subsequent rapid and ongoing expansion of Theo Klein was driven by the systematic development of products and constant additions to the range of toys.
