Yolanda Léderer Mohalyi (1909 – August 23, 1978) was a painter and designer who worked with woodcuts, mosaics, stained glass and murals as well as more usual materials.

[9] In 1931, Yolanda Léderer moved to Brazil to marry a Hungarian chemist, Gabriel Mohalyi, who was employed there.

[9] Already an accomplished artist, Yolanda Mohalyi settled in São Paulo, Brazil and taught drawing and painting.

[3] Many of Mohalyi's works from the 1930s focus on the human figure and show her concern for social injustice and the disadvantaged.

Lasar Segall (1891-1957) made a deep impression on Mohalyi, strongly influencing her figurative work, which became darker and more sombre.

[9] Mohalyi's color palette became similar to Segall's, with a predominance of ochre tones in a dense and elaborate chromatism.

[3] The similarities between her work and Segall's were pointed out by critics such as Mario Pedrosa [pt] and Sérgio Milliet, who called for Mohalyi to develop her own style.

[3] World War II brought changes: in 1939 Gabriel Mohalyi lost his job, and the couple moved to Rio Grande do Sul for a time.

[22] Mohaluyi's first solo exhibition took place in 1945[4][5] at the Instituto de Arquitetos do Brasil (Institute of Architects of Brazil).

[22] Between the 1950s and 1960s, Mohalyi created stained glass windows for the Fundação Armando Alvares Penteado (FAAP) and frescos for the Capela do Cristo Operário [pt][25][22] (with Alfredo Volpi[23] and others) and the church of São Domingo.

In Arezzo, Italy, she was deeply struck by the paintings of Piero della Francesca, a fifteenth-century Renaissance master.

[3] In 1962, she represented Brazil at the first Bienal Americana de Arte in Córdoba, Argentina, where Sir Herbert Read chose her work for inclusion in an exhibition to visit the United States.

[9] They catalogued her work and donated 50 of her paintings to the Museum of Contemporary Art, University of São Paulo (MAC).

[9][34] In 2023 her work was included in the exhibition Action, Gesture, Paint: Women Artists and Global Abstraction 1940-1970 at the Whitechapel Gallery in London.
