She belonged to a group of female Argentine writers in the 1950s and 1960s (like Silvina Bullrich, Beatriz Guido, Sara Gallardo, etc.).

Alberto Girri described Lynch as a writer "little less than unique among us, for her impetus and narrative dexterity and incorporating to our literature characters like Mrs. Ordóñez or Colorado Villanueva, perhaps archetypes of our means."

She graduated with a degree in literature at the Faculty of Philosophy and Letters of Buenos Aires.

She gave lectures in Europe and throughout the Americas (Mexico, Cuba, Paraguay, Chile, Uruguay) and collaborated with La Nación.

She is survived by her children the anthropologist Manuel Ramiro, the philosopher Enrique and Marta Juana Lynch.
