She was born in Alexandria Commune in Teleorman County on 22 January 1913. She had her secondary education in the cosmopolitan atmosphere of Tulcea at that time, in the Highschool for girls, where she took her baccalaureate in 1930. For higher education, she chose to attend the Faculty of Natural Sciences at Bucharest University (1930-1934). At this university, she later obtained a doctorate in biology, with the subject “Contribuţii la cunoaşterea dezvoltării embrionare şi postembrionare a speciilor de Percide din bălţile Deltei Dunării în comparaţie cu cele a câtorva specii de Ciprinide din aceleaşi bălţi / Contributions to the knowledge of embryonic and post-embryonic development of the Percidaes species of the Danube Delta wetlands in comparison with some Cyprinidae species from the same wetlands”. She specialised in hydrobiology, fish farming, fish anatomy and morphology. She worked for over 40 years in problems related to the hydrology and ichthyology of the Danube Delta flood plain. She was constantly interested by the equilibrium between the impact of reef exploitation and the fish populations of the Danube Delta. She worked as a biology teacher at Principesa Ileana Highschool, and asa a university lecturer, but the longest period was as researcher in Tulcea Fish Research Institute, finally becoming its manager. Here she also worked with her husband Vasile Leonte, also a biologist. She won two important national awards for her scientific work. Some of her most interesting scientific papers were: 1942 “Contributions à l'étude du developpement des larves de sander (Lucioperca Sandra C.V.). La nutrition et l'osification du système osseux”, 1943 “Beitrag zur Kenntnis der Entwicklung, Nahrung und Bildung des Knochensystems bei der Larve von Alburnus lucidus Heckel”, 1951 “Contribuții la cunoașterea dezvoltării embrionare și postembrionare a plăticii (Abramis brama L.) din bălțile Deltei Dunării/Contributions to the knowledge of the embryonico and post-embryo development of common bream (Abramis brama L.) from the Danube Delta wetlands, 1958 “Aspectul ihtiologic al Deltei Dunării/The ichthyological aspect of the Danube Delta”, 1960 “Observații hidrobiologice asupra Complexului Razelm în perioada 1955-1956/Observations on the Razelm Complex in the period 1955-1956”, 1961 “Observații asupra migrației peștilor effectuate în anul 1960 în unitățile experimentale Rusca (Delta Dunării)/Observations on the fish migration in 1960 in the Rusca experimental units (Danube Delta)”, 1966 “Date privind hidrobiologia Deltei Dunării/Data regarding Danube Delta hydrobiology”, 1969 “Considerații asupra structurii pe specii a actualei populații piscicole din Delta Dunării/Considerations regarding the present fish population structure of the Danube Delta present”, 1971 “Modificarea biocenozelor acvatice ca urmare a populării cu pești fitofagi în amenajările piscicole din Delta Dunării/Modifications of the aquatic biocoenosis after the introduction of phitophagous carps in the fish farms of the Danube Delta”, 1973 “Posibilitățile de sporire a productivității piscicole în crescătoriile intensive din Delta Dunării/Possibilities of the increasing fish productivity in intensive fish farma of the Danube Delta.” The relevance of the scientific themes approached by Rodica (Teodorescu) Leonte, the research methods she used, and the practical value of her assessments, make the work of this scientist, a life-time work of great significance for the development of Romanian hydrobiology, and an example to be followed.
