Ada Noémi Karinthi, born Etelka Karinthi, later Adél Jusztina Karinthi, name variant: E. Ada Karinthy (20 October 1880, Budapest, – 31 May 1955, Budapest, Józsefváros)[1] was a Hungarian painter and illustrator. She was the sister of writer Frigyes Karinthy and the wife of the painter Viktor Erdei.
Daughter of József Ernő Karinthi and Karolina Szeréna Engel, a bourgeois family in Budapest. Her family was originally Jewish, but converted to Lutheranism shortly before her brother Frigyes was born (1887). Young Etelka played piano and wrote poems in childhood,[2] before studying at the free school in Nagybánya artists' colony between 1906 and 1912. She exhibited at the National Salon (1914, 1916, 1917) and at the 1916/17 winter exhibition of the Hall of Art, mainly watercolors. She also produced works of applied art and book illustrations. On 14 June 1908 Viktor Erdei married non-denominational Ada in Budapest.[3] Their marriage was dissolved in 1922,[4] but they married again on 21 June 1924 in Budapest.[5] Her death was caused by myocardial degeneration and pneumonia.
