His father was the editor Robert Frucht. His family moved to Berlin in 1908 , where he later studied mathematics, physics and philosophy and received his doctorate in 1931 with the dissertation " On the representation of finite Abelian groups through collineations " with Issai Schur . Because of his Jewish origins, he was denied a habilitation and turned to work as an actuary at an insurance company in Trieste and after his dismissal at the beginning of 1939 decided to emigrate to Argentina with his family , which he had now founded, because of the threat of war Actuarial in Buenos Aires .

Through the mediation of Robert Breusch , a contact from his time in Berlin, he began teaching at the Universidad Santa María in Valparaíso ( Chile ), from 1948 to 1968 he was dean of the mathematics and natural science faculty and from 1970 emeritus.

His main area of ​​work was graph theory , in which he proved in 1938 what is known today as Frucht's theorem , according to which a finite graph with an isomorphic group of automorphisms can be found for a given finite group .

Since 1979 Roberto Frucht was a corresponding member of the Chilean Academy of Sciences. He was also a member of the Argentine Mathematical Society and the American Mathematical Society . In 1982 a volume in the Journal of Graph Theory was dedicated to Roberto Frucht .
