In 1933, with Hitler's rise to power in Germany, at only 20 years old Weber set off for Brazil in search of her father, the aviator Edmund Weber, who had moved to the country after World War I. In Rio de Janeiro, she began to work as an artist for the Diários Associados media group, illustrating reports written by Rubem Braga. She also worked as an illustrator for the magazines "O Cruzeiro" and "A Cigarra", for which she was the cover artist from 1933 to 1934. Weber also began drawing political cartoons early on, first for the Constitutional Party in its campaign against Getúlio Vargas.
