Galgóczi was born in western Hungary and graduated from high school in 1949. She wanted to attend The Academy of Performing Arts in Budapest but her parents would not allow it. She enrolled at the University of Budapest, dropping out after a few weeks, and went to work in a factory. She began to write novels, some of which portrayed rural farming life, and was a popular author. One of her finest works, Vidravas ("Otter Trap"), published in 1984, dealt with the tragic 1956 Hungarian uprising against the Russians. Galgóczi also worked in Budapest as a journalist. She was the recipient of the Joszef Attila Prize in 1976 and the Kossuth Prize in 1987. In addition, she served for several years in the Hungarian Parliament.
