[1] Katz began her career in the 1940s, primarily painting portraits and landscapes of Rio de Janeiro.
Persuaded by a friend, the artist Poty Lazzarotto, Katz studied metal engraving with Carlos Oswald at the Rio de Janeiro School of Arts and Crafts.
To obtain the desired effects, Katz engraved up to five matrices and applied up to eight different colors to make multiple impressions of a single print.
[4] Of this process, she said: "color emerged from the evolution of the work, and the multiplication of the matrices brought the possibility of exploring various tonal values.
[7] In 1965, Katz became a professor at the School of Architecture and Urbanism at the University of São Paulo, the same institution where she obtained her master's and doctoral degrees.
