Leopoldo Pedro Presas was born in Barracas, Buenos Aires, on February 21, 1915, the son of a Uruguayan mother and Galician grandparents. He spent his childhood and part of his adolescence in the modest neighborhood of La Mosca, in the Province of Buenos Aires, surrounded by more than twenty uncles, who taught him the most varied things of life.
At the age of 17 he prepared to enter the National Academy of Fine Arts under the tutelage of the painter and engraver Adolfo Sorzio. But then he left his studies and with his group of friends began taking classes with the teacher Lino Spilimbergo at the Argentine Institute of Graphic Arts.

In 1940 he left painting and was employed in a textile design workshop. Later he founded his own workshop, where he met Elsa Legaspi Salgado, whom he married 5 years later and has 3 children: María Gabriela, Fernando and Carlos Manuel.
In 1946 he made his first solo exhibition and began sending works to his salons, but in 1955 in the middle of the Liberation Revolution, his workshop was raided. During the regime of Pedro Eugenio Aramburu he undertook indirect censorship, being unable to exhibit some works.
A few years later, he resumes the animated painting by his friend and artist Santiago Cogorno and begins to make successive individual and collective exhibitions, both nationally and internationally.
He also began to regularly send his works to the salons, obtaining numerous awards including the Grand Prix of Honor at the National Painting Hall in 1959 and the Palanza Prize, awarded by the National Academy of Fine Arts in 1963, among others.
